5  AlternateSubst, MultipleSubst (#2238).
6  ATTENTION: This will change your TTX dumps!
7- [misc.arrayTools] move Vector to its own submodule, and rewrite as a tuple
8  subclass (#2201).
9- [docs] Added a terminology section for varLib (#2209).
10- [varLib] Move rounding to VariationModel, to avoid error accumulation from
11  multiple deltas (#2214)
12- [varLib] Explain merge errors in more human-friendly terms (#2223, #2226)
13- [otlLib] Correct some documentation (#2225)
14- [varLib/otlLib] Allow merging into VariationFont without first saving GPOS
15  PairPos2 (#2229)
16- [subset] Improve PairPosFormat2 subsetting (#2221)
17- [ttLib] TTFont.save: create file on disk as late as possible (#2253)
18- [cffLib] Add missing CFF2 dict operators LanguageGroup and ExpansionFactor
19  (#2249)
20  ATTENTION: This will change your TTX dumps!
21
224.21.1 (released 2021-02-26)
23----------------------------
24
25- [pens] Reverted breaking change that turned ``AbstractPen`` and ``AbstractPointPen``
26  into abstract base classes (#2164, #2198).
27
284.21.0 (released 2021-02-26)
29----------------------------
30
31- [feaLib] Indent anchor statements in ``asFea()`` to make them more legible and
32  diff-able (#2193).
33- [pens] Turn ``AbstractPen`` and ``AbstractPointPen`` into abstract base classes
34  (#2164).
35- [feaLib] Added support for parsing and building ``STAT`` table from AFDKO feature
36  files (#2039).
37- [instancer] Added option to update name table of generated instance using ``STAT``
38  table's axis values (#2189).
39- [bezierTools] Added functions to compute bezier point-at-time, as well as line-line,
40  curve-line and curve-curve intersections (#2192).
41
424.20.0 (released 2021-02-15)
43----------------------------
44
45- [COLRv1] Added ``unbuildColrV1`` to deconstruct COLRv1 otTables to raw json-able
46  data structure; it does the reverse of ``buildColrV1`` (#2171).
47- [feaLib] Allow ``sub X by NULL`` sequence to delete a glyph (#2170).
48- [arrayTools] Fixed ``Vector`` division (#2173).
49- [COLRv1] Define new ``PaintSweepGradient`` (#2172).
50- [otTables] Moved ``Paint.Format`` enum class outside of ``Paint`` class definition,
51  now named ``PaintFormat``. It was clashing with paint instance ``Format`` attribute
52  and thus was breaking lazy load of COLR table which relies on magic ``__getattr__``
53  (#2175).
54- [COLRv1] Replace hand-coded builder functions with otData-driven dynamic
55  implementation (#2181).
56- [COLRv1] Define additional static (non-variable) Paint formats (#2181).
57- [subset] Added support for subsetting COLR v1 and CPAL tables (#2174, #2177).
58- [fontBuilder] Allow ``setupFvar`` to optionally take ``designspaceLib.AxisDescriptor``
59  objects. Added new ``setupAvar`` method. Support localised names for axes and
60  named instances (#2185).
61
624.19.1 (released 2021-01-28)
63----------------------------
64
65- [woff2] An initial off-curve point with an overlap flag now stays an off-curve
66  point after compression.
67
684.19.0 (released 2021-01-25)
69----------------------------
70
71- [codecs] Handle ``errors`` parameter different from 'strict' for the custom
72  extended mac encodings (#2137, #2132).
73- [featureVars] Raise better error message when a script is missing the required
74  default language system (#2154).
75- [COLRv1] Avoid abrupt change caused by rounding ``PaintRadialGradient.c0`` when
76  the start circle almost touches the end circle's perimeter (#2148).
77- [COLRv1] Support building unlimited lists of paints as 255-ary trees of
78  ``PaintColrLayers`` tables (#2153).
79- [subset] Prune redundant format-12 cmap subtables when all non-BMP characters
80  are dropped (#2146).
81- [basePen] Raise ``MissingComponentError`` instead of bare ``KeyError`` when a
82  referenced component is missing (#2145).
83
844.18.2 (released 2020-12-16)
85----------------------------
86
87- [COLRv1] Implemented ``PaintTranslate`` paint format (#2129).
88- [varLib.cff] Fixed unbound local variable error (#1787).
89- [otlLib] Don't crash when creating OpenType class definitions if some glyphs
90  occur more than once (#2125).
91
924.18.1 (released 2020-12-09)
93----------------------------
94
95- [colorLib] Speed optimization for ``LayerV1ListBuilder`` (#2119).
96- [mutator] Fixed missing tab in ``interpolate_cff2_metrics`` (0957dc7a).
97
984.18.0 (released 2020-12-04)
99----------------------------
100
101- [COLRv1] Update to latest draft: added ``PaintRotate`` and ``PaintSkew`` (#2118).
102- [woff2] Support new ``brotlicffi`` bindings for PyPy (#2117).
103- [glifLib] Added ``expectContentsFile`` parameter to ``GlyphSet``, for use when
104  reading existing UFOs, to comply with the specification stating that a
105  ``contents.plist`` file must exist in a glyph set (#2114).
106- [subset] Allow ``LangSys`` tags in ``--layout-scripts`` option (#2112). For example:
107  ``--layout-scripts=arab.dflt,arab.URD,latn``; this will keep ``DefaultLangSys``
108  and ``URD`` language for ``arab`` script, and all languages for ``latn`` script.
109- [varLib.interpolatable] Allow UFOs to be checked; report open paths, non existant
110  glyphs; add a ``--json`` option to produce a machine-readable list of
111  incompatibilities
112- [pens] Added ``QuartzPen`` to create ``CGPath`` from glyph outlines on macOS.
113  Requires pyobjc (#2107).
114- [feaLib] You can export ``FONTTOOLS_LOOKUP_DEBUGGING=1`` to enable feature file
115  debugging info stored in ``Debg`` table (#2106).
116- [otlLib] Build more efficient format 1 and format 2 contextual lookups whenever
117  possible (#2101).
118
1194.17.1 (released 2020-11-16)
120----------------------------
121
122- [colorLib] Fixed regression in 4.17.0 when building COLR v0 table; when color
123  layers are stored in UFO lib plist, we can't distinguish tuples from lists so
124  we need to accept either types (e5439eb9, googlefonts/ufo2ft/issues#426).
125
1264.17.0 (released 2020-11-12)
127----------------------------
128
129- [colorLib/otData] Updated to latest draft ``COLR`` v1 spec (#2092).
130- [svgLib] Fixed parsing error when arc commands' boolean flags are not separated
131  by space or comma (#2094).
132- [varLib] Interpret empty non-default glyphs as 'missing', if the default glyph is
133  not empty (#2082).
134- [feaLib.builder] Only stash lookup location for ``Debg`` if ``Builder.buildLookups_``
135  has cooperated (#2065, #2067).
136- [varLib] Fixed bug in VarStore optimizer (#2073, #2083).
137- [varLib] Add designspace lib key for custom feavar feature tag (#2080).
138- Add HashPointPen adapted from psautohint. With this pen, a hash value of a glyph
139  can be computed, which can later be used to detect glyph changes (#2005).
140
1414.16.1 (released 2020-10-05)
142----------------------------
143
144- [varLib.instancer] Fixed ``TypeError`` exception when instantiating a VF with
145  a GSUB table 1.1 in which ``FeatureVariations`` attribute is present but set to
146  ``None`` -- indicating that optional ``FeatureVariations`` is missing (#2077).
147- [glifLib] Make ``x`` and ``y`` attributes of the ``point`` element required
148  even when validation is turned off, and raise a meaningful ``GlifLibError``
149  message when that happens (#2075).
150
1514.16.0 (released 2020-09-30)
152----------------------------
153
154- [removeOverlaps] Added new module and ``removeOverlaps`` function that merges
155  overlapping contours and components in TrueType glyphs. It requires the
156  `skia-pathops <https://github.com/fonttools/skia-pathops>`__ module.
157  Note that removing overlaps invalidates the TrueType hinting (#2068).
158- [varLib.instancer] Added ``--remove-overlaps`` command-line option.
159  The ``overlap`` option in ``instantiateVariableFont`` now takes an ``OverlapMode``
160  enum: 0: KEEP_AND_DONT_SET_FLAGS, 1: KEEP_AND_SET_FLAGS (default), and 2: REMOVE.
161  The latter is equivalent to calling ``removeOverlaps`` on the generated static
162  instance. The option continues to accept ``bool`` value for backward compatibility.
163
164
1654.15.0 (released 2020-09-21)
166----------------------------
167
168- [plistlib] Added typing annotations to plistlib module. Set up mypy static
169  typechecker to run automatically on CI (#2061).
170- [ttLib] Implement private ``Debg`` table, a reverse-DNS namespaced JSON dict.
171- [feaLib] Optionally add an entry into the ``Debg`` table with the original
172  lookup name (if any), feature name / script / language combination (if any),
173  and original source filename and line location. Annotate the ttx output for
174  a lookup with the information from the Debg table (#2052).
175- [sfnt] Disabled checksum checking by default in ``SFNTReader`` (#2058).
176- [Docs] Document ``mtiLib`` module (#2027).
177- [varLib.interpolatable] Added checks for contour node count and operation type
178  of each node (#2054).
179- [ttLib] Added API to register custom table packer/unpacker classes (#2055).
180
1814.14.0 (released 2020-08-19)
182----------------------------
183
184- [feaLib] Allow anonymous classes in LookupFlags definitions (#2037).
185- [Docs] Better document DesignSpace rules processing order (#2041).
186- [ttLib] Fixed 21-year old bug in ``maxp.maxComponentDepth`` calculation (#2044,
187  #2045).
188- [varLib.models] Fixed misspelled argument name in CLI entry point (81d0042a).
189- [subset] When subsetting GSUB v1.1, fixed TypeError by checking whether the
190  optional FeatureVariations table is present (e63ecc5b).
191- [Snippets] Added snippet to show how to decompose glyphs in a TTF (#2030).
192- [otlLib] Generate GSUB type 5 and GPOS type 7 contextual lookups where appropriate
193  (#2016).
194
1954.13.0 (released 2020-07-10)
196----------------------------
197
198- [feaLib/otlLib] Moved lookup subtable builders from feaLib to otlLib; refactored
199  some common code (#2004, #2007).
200- [docs] Document otlLib module (#2009).
201- [glifLib] Fixed bug with some UFO .glif filenames clashing on case-insensitive
202  filesystems (#2001, #2002).
203- [colorLib] Updated COLRv1 implementation following changes in the draft spec:
204  (#2008, googlefonts/colr-gradients-spec#24).
205
2064.12.1 (released 2020-06-16)
207----------------------------
208
209- [_n_a_m_e] Fixed error in ``addMultilingualName`` with one-character names.
210  Only attempt to recovered malformed UTF-16 data from a ``bytes`` string,
211  not from unicode ``str`` (#1997, #1998).
212
2134.12.0 (released 2020-06-09)
214----------------------------
215
216- [otlLib/varLib] Ensure that the ``AxisNameID`` in the ``STAT`` and ``fvar``
217  tables is grater than 255 as per OpenType spec (#1985, #1986).
218- [docs] Document more modules in ``fontTools.misc`` package: ``filenames``,
219  ``fixedTools``, ``intTools``, ``loggingTools``, ``macCreatorType``, ``macRes``,
220  ``plistlib`` (#1981).
221- [OS/2] Don't calculate whole sets of unicode codepoints, use faster and more memory
222  efficient ranges and bisect lookups (#1984).
223- [voltLib] Support writing back abstract syntax tree as VOLT data (#1983).
224- [voltLib] Accept DO_NOT_TOUCH_CMAP keyword (#1987).
225- [subset/merge] Fixed a namespace clash involving a private helper class (#1955).
226
2274.11.0 (released 2020-05-28)
228----------------------------
229
230- [feaLib] Introduced ``includeDir`` parameter on Parser and IncludingLexer to
231  explicitly specify the directory to search when ``include()`` statements are
232  encountered (#1973).
233- [ufoLib] Silently delete duplicate glyphs within the same kerning group when reading
234  groups (#1970).
235- [ttLib] Set version of COLR table when decompiling COLRv1 (commit 9d8a7e2).
236
2374.10.2 (released 2020-05-20)
238----------------------------
239
240- [sfnt] Fixed ``NameError: SimpleNamespace`` while reading TTC header. The regression
241  was introduced with 4.10.1 after removing ``py23`` star import.
242
2434.10.1 (released 2020-05-19)
244----------------------------
245
246- [sfnt] Make ``SFNTReader`` pickleable even when TTFont is loaded with lazy=True
247  option and thus keeps a reference to an external file (#1962, #1967).
248- [feaLib.ast] Restore backward compatibility (broken in 4.10 with #1905) for
249  ``ChainContextPosStatement`` and ``ChainContextSubstStatement`` classes.
250  Make them accept either list of lookups or list of lists of lookups (#1961).
251- [docs] Document some modules in ``fontTools.misc`` package: ``arrayTools``,
252  ``bezierTools`` ``cliTools`` and ``eexec`` (#1956).
253- [ttLib._n_a_m_e] Fixed ``findMultilingualName()`` when name record's ``string`` is
254  encoded as bytes sequence (#1963).
255
2564.10.0 (released 2020-05-15)
257----------------------------
258
259- [varLib] Allow feature variations to be active across the entire space (#1957).
260- [ufoLib] Added support for ``formatVersionMinor`` in UFO's ``fontinfo.plist`` and for
261  ``formatMinor`` attribute in GLIF file as discussed in unified-font-object/ufo-spec#78.
262  No changes in reading or writing UFOs until an upcoming (non-0) minor update of the
263  UFO specification is published (#1786).
264- [merge] Fixed merging fonts with different versions of ``OS/2`` table (#1865, #1952).
265- [subset] Fixed ``AttributeError`` while subsetting ``ContextSubst`` and ``ContextPos``
266  Format 3 subtable (#1879, #1944).
267- [ttLib.table._m_e_t_a] if data happens to be ascii, emit comment in TTX (#1938).
268- [feaLib] Support multiple lookups per glyph position (#1905).
269- [psCharStrings] Use inheritance to avoid repeated code in initializer (#1932).
270- [Doc] Improved documentation for the following modules: ``afmLib`` (#1933), ``agl``
271  (#1934), ``cffLib`` (#1935), ``cu2qu`` (#1937), ``encodings`` (#1940), ``feaLib``
272  (#1941), ``merge`` (#1949).
273- [Doc] Split off developer-centric info to new page, making front page of docs more
274  user-focused. List all utilities and sub-modules with brief descriptions.
275  Make README more concise and focused (#1914).
276- [otlLib] Add function to build STAT table from high-level description (#1926).
277- [ttLib._n_a_m_e] Add ``findMultilingualName()`` method (#1921).
278- [unicodedata] Update ``RTL_SCRIPTS`` for Unicode 13.0 (#1925).
279- [gvar] Sort ``gvar`` XML output by glyph name, not glyph order (#1907, #1908).
280- [Doc] Added help options to ``fonttools`` command line tool (#1913, #1920).
281  Ensure all fonttools CLI tools have help documentation (#1948).
282- [ufoLib] Only write fontinfo.plist when there actually is content (#1911).
283
2844.9.0 (released 2020-04-29)
285---------------------------
286
287- [subset] Fixed subsetting of FeatureVariations table. The subsetter no longer drops
288  FeatureVariationRecords that have empty substitutions as that will keep the search
289  going and thus change the logic. It will only drop empty records that occur at the
290  end of the FeatureVariationRecords array (#1881).
291- [subset] Remove FeatureVariations table and downgrade GSUB/GPOS to version 0x10000
292  when FeatureVariations contain no FeatureVariationRecords after subsetting (#1903).
293- [agl] Add support for legacy Adobe Glyph List of glyph names in ``fontTools.agl``
294  (#1895).
295- [feaLib] Ignore superfluous script statements (#1883).
296- [feaLib] Hide traceback by default on ``fonttools feaLib`` command line.
297  Use ``--traceback`` option to show (#1898).
298- [feaLib] Check lookup index in chaining sub/pos lookups and print better error
299  message (#1896, #1897).
300- [feaLib] Fix building chained alt substitutions (#1902).
301- [Doc] Included all fontTools modules in the sphinx-generated documentation, and
302  published it to ReadTheDocs for continuous documentation of the fontTools project
303  (#1333). Check it out at https://fonttools.readthedocs.io/. Thanks to Chris Simpkins!
304- [transform] The ``Transform`` class is now subclass of ``typing.NamedTuple``. No
305  change in functionality (#1904).
306
307
3084.8.1 (released 2020-04-17)
309---------------------------
310
311- [feaLib] Fixed ``AttributeError: 'NoneType' has no attribute 'getAlternateGlyphs'``
312  when ``aalt`` feature references a chain contextual substitution lookup
313  (googlefonts/fontmake#648, #1878).
314
3154.8.0 (released 2020-04-16)
316---------------------------
317
318- [feaLib] If Parser is initialized without a ``glyphNames`` parameter, it cannot
319  distinguish between a glyph name containing an hyphen, or a range of glyph names;
320  instead of raising an error, it now interprets them as literal glyph names, while
321  also outputting a logging warning to alert user about the ambiguity (#1768, #1870).
322- [feaLib] When serializing AST to string, emit spaces around hyphens that denote
323  ranges. Also, fixed an issue with CID ranges when round-tripping AST->string->AST
324  (#1872).
325- [Snippets/otf2ttf] In otf2ttf.py script update LSB in hmtx to match xMin (#1873).
326- [colorLib] Added experimental support for building ``COLR`` v1 tables as per
327  the `colr-gradients-spec <https://github.com/googlefonts/colr-gradients-spec/blob/master/colr-gradients-spec.md>`__
328  draft proposal. **NOTE**: both the API and the XML dump of ``COLR`` v1 are
329  susceptible to change while the proposal is being discussed and formalized (#1822).
330
3314.7.0 (released 2020-04-03)
332---------------------------
333
334- [cu2qu] Added ``fontTools.cu2qu`` package, imported from the original
335  `cu2qu <https://github.com/googlefonts/cu2qu>`__ project. The ``cu2qu.pens`` module
336  was moved to ``fontTools.pens.cu2quPen``. The optional cu2qu extension module
337  can be compiled by installing `Cython <https://cython.org/>`__ before installing
338  fonttools from source (i.e. git repo or sdist tarball). The wheel package that
339  is published on PyPI (i.e. the one ``pip`` downloads, unless ``--no-binary``
340  option is used), will continue to be pure-Python for now (#1868).
341
3424.6.0 (released 2020-03-24)
343---------------------------
344
345- [varLib] Added support for building variable ``BASE`` table version 1.1 (#1858).
346- [CPAL] Added ``fromRGBA`` method to ``Color`` class (#1861).
347
348
3494.5.0 (released 2020-03-20)
350---------------------------
351
352- [designspaceLib] Added ``add{Axis,Source,Instance,Rule}Descriptor`` methods to
353  ``DesignSpaceDocument`` class, to initialize new descriptor objects using keyword
354  arguments, and at the same time append them to the current document (#1860).
355- [unicodedata] Update to Unicode 13.0 (#1859).
356
3574.4.3 (released 2020-03-13)
358---------------------------
359
360- [varLib] Always build ``gvar`` table for TrueType-flavored Variable Fonts,
361  even if it contains no variation data. The table is required according to
362  the OpenType spec (#1855, #1857).
363
3644.4.2 (released 2020-03-12)
365---------------------------
366
367- [ttx] Annotate ``LookupFlag`` in XML dump with comment explaining what bits
368  are set and what they mean (#1850).
369- [feaLib] Added more descriptive message to ``IncludedFeaNotFound`` error (#1842).
370
3714.4.1 (released 2020-02-26)
372---------------------------
373
374- [woff2] Skip normalizing ``glyf`` and ``loca`` tables if these are missing from
375  a font (e.g. in NotoColorEmoji using ``CBDT/CBLC`` tables).
376- [timeTools] Use non-localized date parsing in ``timestampFromString``, to fix
377  error when non-English ``LC_TIME`` locale is set (#1838, #1839).
378- [fontBuilder] Make sure the CFF table generated by fontBuilder can be used by varLib
379  without having to compile and decompile the table first. This was breaking in
380  converting the CFF table to CFF2 due to some unset attributes (#1836).
381
3824.4.0 (released 2020-02-18)
383---------------------------
384
385- [colorLib] Added ``fontTools.colorLib.builder`` module, initially with ``buildCOLR``
386  and ``buildCPAL`` public functions. More color font formats will follow (#1827).
387- [fontBuilder] Added ``setupCOLR`` and ``setupCPAL`` methods (#1826).
388- [ttGlyphPen] Quantize ``GlyphComponent.transform`` floats to ``F2Dot14`` to fix
389  round-trip issue when computing bounding boxes of transformed components (#1830).
390- [glyf] If a component uses reference points (``firstPt`` and ``secondPt``) for
391  alignment (instead of X and Y offsets), compute the effective translation offset
392  *after* having applied any transform (#1831).
393- [glyf] When all glyphs have zero contours, compile ``glyf`` table data as a single
394  null byte in order to pass validation by OTS and Windows (#1829).
395- [feaLib] Parsing feature code now ensures that referenced glyph names are part of
396  the known glyph set, unless a glyph set was not provided.
397- [varLib] When filling in the default axis value for a missing location of a source or
398  instance, correctly map the value forward.
399- [varLib] The avar table can now contain mapping output values that are greater than
400  OR EQUAL to the preceeding value, as the avar specification allows this.
401- [varLib] The errors of the module are now ordered hierarchically below VarLibError.
402  See #1821.
403
4044.3.0 (released 2020-02-03)
405---------------------------
406
407- [EBLC/CBLC] Fixed incorrect padding length calculation for Format 3 IndexSubTable
408  (#1817, #1818).
409- [varLib] Fixed error when merging OTL tables and TTFonts were loaded as ``lazy=True``
410  (#1808, #1809).
411- [varLib] Allow to use master fonts containing ``CFF2`` table when building VF (#1816).
412- [ttLib] Make ``recalcBBoxes`` option work also with ``CFF2`` table (#1816).
413- [feaLib] Don't reset ``lookupflag`` in lookups defined inside feature blocks.
414  They will now inherit the current ``lookupflag`` of the feature. This is what
415  Adobe ``makeotf`` also does in this case (#1815).
416- [feaLib] Fixed bug with mixed single/multiple substitutions. If a single substitution
417  involved a glyph class, we were incorrectly using only the first glyph in the class
418  (#1814).
419
4204.2.5 (released 2020-01-29)
421---------------------------
422
423- [feaLib] Do not fail on duplicate multiple substitutions, only warn (#1811).
424- [subset] Optimize SinglePos subtables to Format 1 if all ValueRecords are the same
425  (#1802).
426
4274.2.4 (released 2020-01-09)
428---------------------------
429
430- [unicodedata] Update RTL_SCRIPTS for Unicode 11 and 12.
431
4324.2.3 (released 2020-01-07)
433---------------------------
434
435- [otTables] Fixed bug when splitting `MarkBasePos` subtables as offsets overflow.
436  The mark class values in the split subtable were not being updated, leading to
437  invalid mark-base attachments (#1797, googlefonts/noto-source#145).
438- [feaLib] Only log a warning instead of error when features contain duplicate
439  substitutions (#1767).
440- [glifLib] Strip XML comments when parsing with lxml (#1784, #1785).
441
4424.2.2 (released 2019-12-12)
443---------------------------
444
445- [subset] Fixed issue with subsetting FeatureVariations table when the index
446  of features changes as features get dropped. The feature index need to be
447  remapped to point to index of the remaining features (#1777, #1782).
448- [fontBuilder] Added `addFeatureVariations` method to `FontBuilder` class. This
449  is a shorthand for calling `featureVars.addFeatureVariations` on the builder's
450  TTFont object (#1781).
451- [glyf] Fixed the flags bug in glyph.drawPoints() like we did for glyph.draw()
452  (#1771, #1774).
453
4544.2.1 (released 2019-12-06)
455---------------------------
456
457- [glyf] Use the ``flagOnCurve`` bit mask in ``glyph.draw()``, so that we ignore
458  the ``overlap`` flag that may be set when instantiating variable fonts (#1771).
459
4604.2.0 (released 2019-11-28)
461---------------------------
462
463- [pens] Added the following pens:
464
465  * ``roundingPen.RoundingPen``: filter pen that rounds coordinates and components'
466    offsets to integer;
467  * ``roundingPen.RoundingPointPen``: like the above, but using PointPen protocol.
468  * ``filterPen.FilterPointPen``: base class for filter point pens;
469  * ``transformPen.TransformPointPen``: filter point pen to apply affine transform;
470  * ``recordingPen.RecordingPointPen``: records and replays point-pen commands.
471
472- [ttGlyphPen] Always round float coordinates and component offsets to integers
473  (#1763).
474- [ufoLib] When converting kerning groups from UFO2 to UFO3, avoid confusing
475  groups with the same name as one of the glyphs (#1761, #1762,
476  unified-font-object/ufo-spec#98).
477
4784.1.0 (released 2019-11-18)
479---------------------------
480
481- [instancer] Implemented restricting axis ranges (level 3 partial instancing).
482  You can now pass ``{axis_tag: (min, max)}`` tuples as input to the
483  ``instantiateVariableFont`` function. Note that changing the default axis
484  position is not supported yet. The command-line script also accepts axis ranges
485  in the form of colon-separated float values, e.g. ``wght=400:700`` (#1753, #1537).
486- [instancer] Never drop STAT ``DesignAxis`` records, but only prune out-of-range
487  ``AxisValue`` records.
488- [otBase/otTables] Enforce that VarStore.RegionAxisCount == fvar.axisCount, even
489  when regions list is empty to appease OTS < v8.0 (#1752).
490- [designspaceLib] Defined new ``processing`` attribute for ``<rules>`` element,
491  with values "first" or "last", plus other editorial changes to DesignSpace
492  specification. Bumped format version to 4.1 (#1750).
493- [varLib] Improved error message when masters' glyph orders do not match (#1758,
494  #1759).
495- [featureVars] Allow to specify custom feature tag in ``addFeatureVariations``;
496  allow said feature to already exist, in which case we append new lookup indices
497  to existing features. Implemented ``<rules>`` attribute ``processing`` according to
498  DesignSpace specification update in #1750. Depending on this flag, we generate
499  either an 'rvrn' (always processed first) or a 'rclt' feature (follows lookup order,
500  therefore last) (#1747, #1625, #1371).
501- [ttCollection] Added support for context manager auto-closing via ``with`` statement
502  like with ``TTFont`` (#1751).
503- [unicodedata] Require unicodedata2 >= 12.1.0.
504- [py2.py3] Removed yet more PY2 vestiges (#1743).
505- [_n_a_m_e] Fixed issue when comparing NameRecords with different string types (#1742).
506- [fixedTools] Changed ``fixedToFloat`` to not do any rounding but simply return
507  ``value / (1 << precisionBits)``. Added ``floatToFixedToStr`` and
508  ``strToFixedToFloat`` functions to be used when loading from or dumping to XML.
509  Fixed values (e.g. fvar axes and instance coordinates, avar mappings, etc.) are
510  are now stored as un-rounded decimal floats upon decompiling (#1740, #737).
511- [feaLib] Fixed handling of multiple ``LigatureCaret`` statements for the same glyph.
512  Only the first rule per glyph is used, additional ones are ignored (#1733).
513
5144.0.2 (released 2019-09-26)
515---------------------------
516
517- [voltLib] Added support for ``ALL`` and ``NONE`` in ``PROCESS_MARKS`` (#1732).
518- [Silf] Fixed issue in ``Silf`` table compilation and decompilation regarding str vs
519  bytes in python3 (#1728).
520- [merge] Handle duplicate glyph names better: instead of appending font index to
521  all glyph names, use similar code like we use in ``post`` and ``CFF`` tables (#1729).
522
5234.0.1 (released 2019-09-11)
524---------------------------
525
526- [otTables] Support fixing offset overflows in ``MultipleSubst`` lookup subtables
527  (#1706).
528- [subset] Prune empty strikes in ``EBDT`` and ``CBDT`` table data (#1698, #1633).
529- [pens] Fixed issue in ``PointToSegmentPen`` when last point of closed contour has
530  same coordinates as the starting point and was incorrectly dropped (#1720).
531- [Graphite] Fixed ``Sill`` table output to pass OTS (#1705).
532- [name] Added ``removeNames`` method to ``table__n_a_m_e`` class (#1719).
533- [ttLib] Added aliases for renamed entries ``ascender`` and ``descender`` in
534  ``hhea`` table (#1715).
535
5364.0.0 (released 2019-08-22)
537---------------------------
538
539- NOTE: The v4.x version series only supports Python 3.6 or greater. You can keep
540  using fonttools 3.x if you need support for Python 2.
541- [py23] Removed all the python2-only code since it is no longer reachable, thus
542  unused; only the Python3 symbols were kept, but these are no-op. The module is now
543  DEPRECATED and will removed in the future.
544- [ttLib] Fixed UnboundLocalError for empty loca/glyph tables (#1680). Also, allow
545  the glyf table to be incomplete when dumping to XML (#1681).
546- [varLib.models] Fixed KeyError while sorting masters and there are no on-axis for
547  a given axis (38a8eb0e).
548- [cffLib] Make sure glyph names are unique (#1699).
549- [feaLib] Fix feature parser to correctly handle octal numbers (#1700).
550
5513.44.0 (released 2019-08-02)
552----------------------------
553
554- NOTE: This is the last scheduled release to support Python 2.7. The upcoming fonttools
555  v4.x series is going to require Python 3.6 or greater.
556- [varLib] Added new ``varLib.instancer`` module for partially instantiating variable
557  fonts. This extends (and will eventually replace) ``varLib.mutator`` module, as
558  it allows to create not just full static instances from a variable font, but also
559  "partial" or "less variable" fonts where some of the axes are dropped or
560  instantiated at a particular value.
561  Also available from the command-line as `fonttools varLib.instancer --help`
562  (#1537, #1628).
563- [cffLib] Added support for ``FDSelect`` format 4 (#1677).
564- [subset] Added support for subsetting ``sbix`` (Apple bitmap color font) table.
565- [t1Lib] Fixed issue parsing ``eexec`` section in Type1 fonts when whitespace
566  characters are interspersed among the trailing zeros (#1676).
567- [cffLib.specializer] Fixed bug in ``programToCommands`` with CFF2 charstrings (#1669).
568
5693.43.2 (released 2019-07-10)
570----------------------------
571
572- [featureVars] Fixed region-merging code on python3 (#1659).

576----------------------------
577
578- [subset] Fixed regression when passing ``--flavor=woff2`` option with an input font
579  that was already compressed as WOFF 1.0 (#1650).
580
5813.43.0 (released 2019-06-18)
582----------------------------
583
584- [woff2] Added support for compressing/decompressing WOFF2 fonts with non-transformed
585  ``glyf`` and ``loca`` tables, as well as with transformed ``hmtx`` table.
586  Removed ``Snippets/woff2_compress.py`` and ``Snippets/woff2_decompress.py`` scripts,
587  and replaced them with a new console entry point ``fonttools ttLib.woff2``
588  that provides two sub-commands ``compress`` and ``decompress``.
589- [varLib.cff] Fixed bug when merging CFF2 ``PrivateDicts``. The ``PrivateDict``
590  data from the first region font was incorrecty used for all subsequent fonts.
591  The bug would only affect variable CFF2 fonts with hinting (#1643, #1644).
592  Also, fixed a merging bug when VF masters have no blends or marking glyphs (#1632,
593  #1642).
594- [loggingTools] Removed unused backport of ``LastResortLogger`` class.
595- [subset] Gracefully handle partial MATH table (#1635).
596- [featureVars] Avoid duplicate references to ``rvrn`` feature record in
597  ``DefaultLangSys`` tables when calling ``addFeatureVariations`` on a font that
598  does not already have a ``GSUB`` table (aa8a5bc6).
599- [varLib] Fixed merging of class-based kerning. Before, the process could introduce
600  rogue kerning values and variations for random classes against class zero (everything
601  not otherwise classed).
602- [varLib] Fixed merging GPOS tables from master fonts with different number of
603  ``SinglePos`` subtables (#1621, #1641).
604- [unicodedata] Updated Blocks, Scripts and ScriptExtensions to Unicode 12.1.

615- [subset] Update font extents in head table (#1612).
616- [subset] Make --retain-gids truncate empty glyphs after the last non-empty glyph
617  (#1611).
618- [requirements] Updated ``unicodedata2`` backport for Unicode 12.0.

639  previous typo fix (#1597). Decode languange code as UTF-8 in ``Sill`` table's
640  ``decompile`` method (#1600).
641
6423.41.0 (released 2019-04-29)
643----------------------------
644
645- [varLib/cffLib] Added support for building ``CFF2`` variable font from sparse
646  masters, or masters with more than one model (multiple ``VarStore.VarData``).
647  In ``cffLib.specializer``, added support for ``CFF2`` CharStrings with
648  ``blend`` operators (#1547, #1591).
649- [subset] Fixed subsetting ``HVAR`` and ``VVAR`` with ``--retain-gids`` option,
650  and when advances mapping is null while sidebearings mappings are non-null
651  (#1587, #1588).
652- Added ``otlLib.maxContextCalc`` module to compute ``OS/2.usMaxContext`` value.
653  Calculate it automatically when compiling features with feaLib. Added option
654  ``--recalc-max-context`` to ``subset`` module (#1582).
655- [otBase/otTables] Fixed ``AttributeError`` on missing OT table fields after
656  importing font from TTX (#1584).
657- [graphite] Fixed typo ``Silf`` table's ``decompile`` method (#1586).
658- [otlLib] Better compress ``GPOS`` SinglePos (LookupType 1) subtables (#1539).
659

667- [voltLib] Allow passing file-like object to Parser.
668- [arrayTools/glyf] ``calcIntBounds`` (used to compute bounding boxes of glyf
669  table's glyphs) now uses ``otRound`` instead of ``round3`` (#1566).
670- [svgLib] Added support for converting more SVG shapes to path ``d`` strings
671  (ellipse, line, polyline), as well as support for ``transform`` attributes.
672  Only ``matrix`` transformations are currently supported (#1564, #1564).

690- [designspaceLib] Use axes maps when normalizing locations in
691  DesignSpaceDocument (#1226, #1521), and when finding default source (#1535).
692- [mutator] Set ``OVERLAP_SIMPLE`` and ``OVERLAP_COMPOUND`` glyf flags by
693  default in ``instantiateVariableFont``. Added ``--no-overlap`` cli option
694  to disable this (#1518).
695- [subset] Fixed subsetting ``VVAR`` table (#1516, #1517).
696  Fixed subsetting an ``HVAR`` table that has an ``AdvanceWidthMap`` when the
697  option ``--retain-gids`` is used.

699  Fixed double indentation of ``subtable`` statement (#1512).
700  Added support for ``subtable`` statement in more places than just PairPos
701  lookups (#1520).
702  Handle lookupflag 0 and lookupflag without a value (#1540).

734  crash in ``interpolate_layout()`` when ``deepcopy``-ing OTFs.
735
7363.37.1 (released 2019-02-05)
737----------------------------
738

740  source.font attributes.
741- [varLib] Fixed an MVAR table generation crash when sparse masters were
742  involved.
743- [voltLib] ``parse_coverage_()`` returns a tuple instead of an ast.Enum.

756- [voltLib] Fixed parsing glyph groups. Distinguish different PROCESS_MARKS.
757  Accept COMPONENT glyph type.
758- [feaLib] Distinguish missing value and explicit ``<NULL>`` for PairPos2
759  format A (#1459). Round-trip ``useExtension`` keyword. Implemented
760  ``ValueRecord.asFea`` method.
761- [subset] Insert empty widths into hdmx when retaining gids (#1458).
762
7633.36.0 (released 2019-01-17)
764----------------------------
765
766- [ttx] Added ``--no-recalc-timestamp`` option to keep the original font's
767  ``head.modified`` timestamp (#1455, #46).
768- [ttx/psCharStrings] Fixed issues while dumping and round-tripping CFF2 table
769  with ttx (#1451, #1452, #1456).

771  the ``END`` operator in .vtp file (#1453).
772- [varLib] Use sentinel value -0x8000 (-32768) to ignore post.underlineThickness
773  and post.underlinePosition when generating MVAR deltas (#1449,
774  googlei18n/ufo2ft#308).
775- [subset] Added ``--retain-gids`` option to subset font without modifying the
776  current glyph indices (#1443, #1447).
777- [ufoLib] Replace deprecated calls to ``getbytes`` and ``setbytes`` with new
778  equivalent ``readbytes`` and ``writebytes`` calls. ``fs`` >= 2.2 no required.
779- [varLib] Allow loading masters from TTX files as well (#1441).
780
7813.35.2 (released 2019-01-14)

794
7953.35.0 (released 2019-01-07)

797
798- [psCharStrings] In ``encodeFloat`` function, use float's "general format" with
799  8 digits of precision (i.e. ``%8g``) instead of ``str()``. This works around
800  a macOS rendering issue when real numbers in CFF table are too long, and
801  also makes sure that floats are encoded with the same precision in python 2.7
802  and 3.x (#1430, googlei18n/ufo2ft#306).
803- [_n_a_m_e/fontBuilder] Make ``_n_a_m_e_table.addMultilingualName`` also add
804  Macintosh (platformID=1) names by default. Added options to ``FontBuilder``
805  ``setupNameTable`` method to optionally disable Macintosh or Windows names.
806  (#1359, #1431).
807- [varLib] Make ``build`` optionally accept a ``DesignSpaceDocument`` object,
808  instead of a designspace file path. The caller can now set the ``font``
809  attribute of designspace's sources to a TTFont object, thus allowing to
810  skip filenames manipulation altogether (#1416, #1425).
811- [sfnt] Allow SFNTReader objects to be deep-copied.
812- Require typing>=3.6.4 on py27 to fix issue with singledispatch (#1423).
813- [designspaceLib/t1Lib/macRes] Fixed some cases where pathlib.Path objects were
814  not accepted (#1421).
815- [varLib] Fixed merging of multiple PairPosFormat2 subtables (#1411).
816- [varLib] The default STAT table version is now set to 1.1, to improve
817  compatibility with legacy applications (#1413).
818
8193.34.2 (released 2018-12-17)
820----------------------------
821
822- [merge] Fixed AssertionError when none of the script tables in GPOS/GSUB have
823  a DefaultLangSys record (#1408, 135a4a1).
824
8253.34.1 (released 2018-12-17)
826----------------------------
827
828- [varLib] Work around macOS rendering issue for composites without gvar entry (#1381).
829
8303.34.0 (released 2018-12-14)
831----------------------------
832
833- [varLib] Support generation of CFF2 variable fonts. ``model.reorderMasters()``
834  now supports arbitrary mapping. Fix handling of overlapping ranges for feature
835  variations (#1400).
836- [cffLib, subset] Code clean-up and fixing related to CFF2 support.
837- [ttLib.tables.ttProgram] Use raw strings for regex patterns (#1389).
838- [fontbuilder] Initial support for building CFF2 fonts. Set CFF's
839  ``FontMatrix`` automatically from unitsPerEm.
840- [plistLib] Accept the more general ``collections.Mapping`` instead of the
841  specific ``dict`` class to support custom data classes that should serialize
842  to dictionaries.
843
8443.33.0 (released 2018-11-30)
845----------------------------
846- [subset] subsetter bug fix with variable fonts.
847- [varLib.featureVar] Improve FeatureVariations generation with many rules.
848- [varLib] Enable sparse masters when building variable fonts:
849  https://github.com/fonttools/fonttools/pull/1368#issuecomment-437257368
850- [varLib.mutator] Add IDEF for GETVARIATION opcode, for handling hints in an
851  instance.
852- [ttLib] Ignore the length of kern table subtable format 0
853
8543.32.0 (released 2018-11-01)
855----------------------------
856
857- [ufoLib] Make ``UFOWriter`` a subclass of ``UFOReader``, and use mixins
858  for shared methods (#1344).
859- [featureVars] Fixed normalization error when a condition's minimum/maximum
860  attributes are missing in designspace ``<rule>`` (#1366).
861- [setup.py] Added ``[plot]`` to extras, to optionally install ``matplotlib``,
862  needed to use the ``fonTools.varLib.plot`` module.
863- [varLib] Take total bounding box into account when resolving model (7ee81c8).
864  If multiple axes have the same range ratio, cut across both (62003f4).
865- [subset] Don't error if ``STAT`` has no ``AxisValue`` tables.
866- [fontBuilder] Added a new submodule which contains a ``FontBuilder`` wrapper
867  class around ``TTFont`` that makes it easier to create a working TTF or OTF
868  font from scratch with code. NOTE: the API is still experimental and may
869  change in future versions.
870
8713.31.0 (released 2018-10-21)
872----------------------------
873
874- [ufoLib] Merged the `ufoLib <https://github.com/unified-font-objects/ufoLib>`__
875  master branch into a new ``fontTools.ufoLib`` package (#1335, #1095).
876  Moved ``ufoLib.pointPen`` module to ``fontTools.pens.pointPen``.
877  Moved ``ufoLib.etree`` module to ``fontTools.misc.etree``.
878  Moved ``ufoLib.plistlib`` module to ``fontTools.misc.plistlib``.
879  To use the new ``fontTools.ufoLib`` module you need to install fonttools
880  with the ``[ufo]`` extra, or you can manually install the required additional
881  dependencies (cf. README.rst).
882- [morx] Support AAT action type to insert glyphs and clean up compilation
883  of AAT action tables (4a1871f, 2011ccf).
884- [subset] The ``--no-hinting`` on a CFF font now also drops the optional
885  hinting keys in Private dict: ``ForceBold``, ``LanguageGroup``, and
886  ``ExpansionFactor`` (#1322).
887- [subset] Include nameIDs referenced by STAT table (#1327).
888- [loggingTools] Added ``msg=None`` argument to
889  ``CapturingLogHandler.assertRegex`` (0245f2c).
890- [varLib.mutator] Implemented ``FeatureVariations`` instantiation (#1244).
891- [g_l_y_f] Added PointPen support to ``_TTGlyph`` objects (#1334).
892
8933.30.0 (released 2018-09-18)
894----------------------------
895
896- [feaLib] Skip building noop class PairPos subtables when Coverage is NULL
897  (#1318).
898- [ttx] Expose the previously reserved bit flag ``OVERLAP_SIMPLE`` of
899  glyf table's contour points in the TTX dump. This is used in some
900  implementations to specify a non-zero fill with overlapping contours (#1316).
901- [ttLib] Added support for decompiling/compiling ``TS1C`` tables containing
902  VTT sources for ``cvar`` variation table (#1310).
903- [varLib] Use ``fontTools.designspaceLib`` to read DesignSpaceDocument. The
904  ``fontTools.varLib.designspace`` module is now deprecated and will be removed
905  in future versions. The presence of an explicit ``axes`` element is now
906  required in order to build a variable font (#1224, #1313).
907- [varLib] Implemented building GSUB FeatureVariations table from the ``rules``
908  element of DesignSpace document (#1240, #713, #1314).
909- [subset] Added ``--no-layout-closure`` option to not expand the subset with
910  the glyphs produced by OpenType layout features. Instead, OpenType features
911  will be subset to only rules that are relevant to the otherwise-specified
912  glyph set (#43, #1121).
913
9143.29.1 (released 2018-09-10)
915----------------------------
916
917- [feaLib] Fixed issue whereby lookups from DFLT/dflt were not included in the
918  DFLT/non-dflt language systems (#1307).
919- [graphite] Fixed issue on big-endian architectures (e.g. ppc64) (#1311).
920- [subset] Added ``--layout-scripts`` option to add/exclude set of OpenType
921  layout scripts that will be preserved. By default all scripts are retained
922  (``'*'``) (#1303).
923
9243.29.0 (released 2018-07-26)
925----------------------------
926
927- [feaLib] In the OTL table builder, when the ``name`` table is excluded
928  from the list of tables to be build, skip compiling ``featureNames`` blocks,
929  as the records referenced in ``FeatureParams`` table don't exist (68951b7).
930- [otBase] Try ``ExtensionLookup`` if other offset-overflow methods fail
931  (05f95f0).
932- [feaLib] Added support for explicit ``subtable;`` break statements in
933  PairPos lookups; previously these were ignored (#1279, #1300, #1302).
934- [cffLib.specializer] Make sure the stack depth does not exceed maxstack - 1,
935  so that a subroutinizer can insert subroutine calls (#1301,
936  https://github.com/googlei18n/ufo2ft/issues/266).
937- [otTables] Added support for fixing offset overflow errors occurring inside
938  ``MarkBasePos`` subtables (#1297).
939- [subset] Write the default output file extension based on ``--flavor`` option,
940  or the value of ``TTFont.sfntVersion`` (d7ac0ad).
941- [unicodedata] Updated Blocks, Scripts and ScriptExtensions for Unicode 11
942  (452c85e).
943- [xmlWriter] Added context manager to XMLWriter class to autoclose file
944  descriptor on exit (#1290).
945- [psCharStrings] Optimize the charstring's bytecode by encoding as integers
946  all float values that have no decimal portion (8d7774a).
947- [ttFont] Fixed missing import of ``TTLibError`` exception (#1285).
948- [feaLib] Allow any languages other than ``dflt`` under ``DFLT`` script
949  (#1278, #1292).
950
9513.28.0 (released 2018-06-19)
952----------------------------
953
954- [featureVars] Added experimental module to build ``FeatureVariations``
955  tables. Still needs to be hooked up to ``varLib.build`` (#1240).
956- [fixedTools] Added ``otRound`` to round floats to nearest integer towards
957  positive Infinity. This is now used where we deal with visual data like X/Y
958  coordinates, advance widths/heights, variation deltas, and similar (#1274,
959  #1248).
960- [subset] Improved GSUB closure memoize algorithm.
961- [varLib.models] Fixed regression in model resolution (180124, #1269).
962- [feaLib.ast] Fixed error when converting ``SubtableStatement`` to string
963  (#1275).
964- [varLib.mutator] Set ``OS/2.usWeightClass`` and ``usWidthClass``, and
965  ``post.italicAngle`` based on the 'wght', 'wdth' and 'slnt' axis values
966  (#1276, #1264).
967- [py23/loggingTools] Don't automatically set ``logging.lastResort`` handler
968  on py27. Moved ``LastResortLogger`` to the ``loggingTools`` module (#1277).
969
9703.27.1 (released 2018-06-11)
971----------------------------
972
973- [ttGlyphPen] Issue a warning and skip building non-existing components
974  (https://github.com/googlei18n/fontmake/issues/411).
975- [tests] Fixed issue running ttx_test.py from a tagged commit.
976
9773.27.0 (released 2018-06-11)
978----------------------------
979
980- [designspaceLib] Added new ``conditionSet`` element to ``rule`` element in
981  designspace document. Bumped ``format`` attribute to ``4.0`` (previously,
982  it was formatted as an integer). Removed ``checkDefault``, ``checkAxes``
983  methods, and any kind of guessing about the axes when the ``<axes>`` element
984  is missing. The default master is expected at the intersection of all default
985  values for each axis (#1254, #1255, #1267).
986- [cffLib] Fixed issues when compiling CFF2 or converting from CFF when the
987  font has an FDArray (#1211, #1271).
988- [varLib] Avoid attempting to build ``cvar`` table when ``glyf`` table is not
989  present, as is the case for CFF2 fonts.
990- [subset] Handle None coverages in MarkGlyphSets; revert commit 02616ab that
991  sets empty Coverage tables in MarkGlyphSets to None, to make OTS happy.
992- [ttFont] Allow to build glyph order from ``maxp.numGlyphs`` when ``post`` or
993  ``cmap`` are missing.
994- [ttFont] Added ``__len__`` method to ``_TTGlyphSet``.
995- [glyf] Ensure ``GlyphCoordinates`` never overflow signed shorts (#1230).
996- [py23] Added alias for ``itertools.izip`` shadowing the built-in ``zip``.
997- [loggingTools] Memoize ``log`` property of ``LogMixin`` class (fbab12).
998- [ttx] Impoved test coverage (#1261).
999- [Snippets] Addded script to append a suffix to all family names in a font.
1000- [varLib.plot] Make it work with matplotlib >= 2.1 (b38e2b).
1001
10023.26.0 (released 2018-05-03)
1003----------------------------
1004
1005- [designspace] Added a new optional ``layer`` attribute to the source element,
1006  and a corresponding ``layerName`` attribute to the ``SourceDescriptor``
1007  object (#1253).
1008  Added ``conditionset`` element to the ``rule`` element to the spec, but not
1009  implemented in designspace reader/writer yet (#1254).
1010- [varLib.models] Refine modeling one last time (0ecf5c5).
1011- [otBase] Fixed sharing of tables referred to by different offset sizes
1012  (795f2f9).
1013- [subset] Don't drop a GDEF that only has VarStore (fc819d6). Set to None
1014  empty Coverage tables in MarkGlyphSets (02616ab).
1015- [varLib]: Added ``--master-finder`` command-line option (#1249).
1016- [varLib.mutator] Prune fvar nameIDs from instance's name table (#1245).
1017- [otTables] Allow decompiling bad ClassDef tables with invalid format, with
1018  warning (#1236).
1019- [varLib] Make STAT v1.2 and reuse nameIDs from fvar table (#1242).
1020- [varLib.plot] Show master locations. Set axis limits to -1, +1.
1021- [subset] Handle HVAR direct mapping. Passthrough 'cvar'.
1022  Added ``--font-number`` command-line option for collections.
1023- [t1Lib] Allow a text encoding to be specified when parsing a Type 1 font
1024  (#1234). Added ``kind`` argument to T1Font constructor (c5c161c).
1025- [ttLib] Added context manager API to ``TTFont`` class, so it can be used in
1026  ``with`` statements to auto-close the file when exiting the context (#1232).
1027
10283.25.0 (released 2018-04-03)
1029----------------------------
1030
1031- [varLib] Improved support-resolution algorithm. Previously, the on-axis
1032  masters would always cut the space. They don't anymore. That's more
1033  consistent, and fixes the main issue Erik showed at TYPO Labs 2017.
1034  Any varfont built that had an unusual master configuration will change
1035  when rebuilt (42bef17, a523a697,
1036  https://github.com/googlei18n/fontmake/issues/264).
1037- [varLib.models] Added a ``main()`` entry point, that takes positions and
1038  prints model results.
1039- [varLib.plot] Added new module to plot a designspace's
1040  VariationModel. Requires ``matplotlib``.
1041- [varLib.mutator] Added -o option to specify output file path (2ef60fa).
1042- [otTables] Fixed IndexError while pruning of HVAR pre-write (6b6c34a).
1043- [varLib.models] Convert delta array to floats if values overflows signed
1044  short integer (0055f94).
1045
10463.24.2 (released 2018-03-26)
1047----------------------------
1048
1049- [otBase] Don't fail during ``ValueRecord`` copy if src has more items.
1050  We drop hinting in the subsetter by simply changing ValueFormat, without
1051  cleaning up the actual ValueRecords. This was causing assertion error if
1052  a variable font was subsetted without hinting and then passed directly to
1053  the mutator for instantiation without first it saving to disk.
1054
10553.24.1 (released 2018-03-06)
1056----------------------------
1057
1058- [varLib] Don't remap the same ``DeviceTable`` twice in VarStore optimizer
1059  (#1206).
1060- [varLib] Add ``--disable-iup`` option to ``fonttools varLib`` script,
1061  and a ``optimize=True`` keyword argument to ``varLib.build`` function,
1062  to optionally disable IUP optimization while building varfonts.
1063- [ttCollection] Fixed issue while decompiling ttc with python3 (#1207).
1064
10653.24.0 (released 2018-03-01)
1066----------------------------
1067
1068- [ttGlyphPen] Decompose composite glyphs if any components' transform is too
1069  large to fit a ``F2Dot14`` value, or clamp transform values that are
1070  (almost) equal to +2.0 to make them fit and avoid decomposing (#1200,
1071  #1204, #1205).
1072- [ttx] Added new ``-g`` option to dump glyphs from the ``glyf`` table
1073  splitted as individual ttx files (#153, #1035, #1132, #1202).
1074- Copied ``ufoLib.filenames`` module to ``fontTools.misc.filenames``, used
1075  for the ttx split-glyphs option (#1202).
1076- [feaLib] Added support for ``cvParameters`` blocks in Character Variant
1077  feautures ``cv01-cv99`` (#860, #1169).
1078- [Snippets] Added ``checksum.py`` script to generate/check SHA1 hash of
1079  ttx files (#1197).
1080- [varLib.mutator] Fixed issue while instantiating some variable fonts
1081  whereby the horizontal advance width computed from ``gvar`` phantom points
1082  could turn up to be negative (#1198).
1083- [varLib/subset] Fixed issue with subsetting GPOS variation data not
1084  picking up ``ValueRecord`` ``Device`` objects (54fd71f).
1085- [feaLib/voltLib] In all AST elements, the ``location`` is no longer a
1086  required positional argument, but an optional kewyord argument (defaults
1087  to ``None``). This will make it easier to construct feature AST from
1088  code (#1201).
1089
1090
10913.23.0 (released 2018-02-26)
1092----------------------------
1093
1094- [designspaceLib] Added an optional ``lib`` element to the designspace as a
1095  whole, as well as to the instance elements, to store arbitrary data in a
1096  property list dictionary, similar to the UFO's ``lib``. Added an optional
1097  ``font`` attribute to the ``SourceDescriptor``, to allow operating on
1098  in-memory font objects (#1175).
1099- [cffLib] Fixed issue with lazy-loading of attributes when attempting to
1100  set the CFF TopDict.Encoding (#1177, #1187).
1101- [ttx] Fixed regression introduced in 3.22.0 that affected the split tables
1102  ``-s`` option (#1188).
1103- [feaLib] Added ``IncludedFeaNotFound`` custom exception subclass, raised
1104  when an included feature file cannot be found (#1186).
1105- [otTables] Changed ``VarIdxMap`` to use glyph names internally instead of
1106  glyph indexes. The old ttx dumps of HVAR/VVAR tables that contain indexes
1107  can still be imported (21cbab8, 38a0ffb).
1108- [varLib] Implemented VarStore optimizer (#1184).
1109- [subset] Implemented pruning of GDEF VarStore, HVAR and MVAR (#1179).
1110- [sfnt] Restore backward compatiblity with ``numFonts`` attribute of
1111  ``SFNTReader`` object (#1181).
1112- [merge] Initial support for merging ``LangSysRecords`` (#1180).
1113- [ttCollection] don't seek(0) when writing to possibly unseekable strems.
1114- [subset] Keep all ``--name-IDs`` from 0 to 6 by default (#1170, #605, #114).
1115- [cffLib] Added ``width`` module to calculate optimal CFF default and
1116  nominal glyph widths.
1117- [varLib] Don’t fail if STAT already in the master fonts (#1166).
1118
11193.22.0 (released 2018-02-04)
1120----------------------------
1121
1122- [subset] Support subsetting ``endchar`` acting as ``seac``-like components
1123  in ``CFF`` (fixes #1162).
1124- [feaLib] Allow to build from pre-parsed ``ast.FeatureFile`` object.
1125  Added ``tables`` argument to only build some tables instead of all (#1159,
1126  #1163).
1127- [textTools] Replaced ``safeEval`` with ``ast.literal_eval`` (#1139).
1128- [feaLib] Added option to the parser to not resolve ``include`` statements
1129  (#1154).
1130- [ttLib] Added new ``ttCollection`` module to read/write TrueType and
1131  OpenType Collections. Exports a ``TTCollection`` class with a ``fonts``
1132  attribute containing a list of ``TTFont`` instances, the methods ``save``
1133  and ``saveXML``, plus some list-like methods. The ``importXML`` method is
1134  not implemented yet (#17).
1135- [unicodeadata] Added ``ot_tag_to_script`` function that converts from
1136  OpenType script tag to Unicode script code.
1137- Added new ``designspaceLib`` subpackage, originally from Erik Van Blokland's
1138  ``designSpaceDocument``: https://github.com/LettError/designSpaceDocument
1139  NOTE: this is not yet used internally by varLib, and the API may be subject
1140  to changes (#911, #1110, LettError/designSpaceDocument#28).
1141- Added new FontTools icon images (8ee7c32).
1142- [unicodedata] Added ``script_horizontal_direction`` function that returns
1143  either "LTR" or "RTL" given a unicode script code.
1144- [otConverters] Don't write descriptive name string as XML comment if the
1145  NameID value is 0 (== NULL) (#1151, #1152).
1146- [unicodedata] Add ``ot_tags_from_script`` function to get the list of
1147  OpenType script tags associated with unicode script code (#1150).
1148- [feaLib] Don't error when "enumerated" kern pairs conflict with preceding
1149  single pairs; emit warning and chose the first value (#1147, #1148).
1150- [loggingTools] In ``CapturingLogHandler.assertRegex`` method, match the
1151  fully formatted log message.
1152- [sbix] Fixed TypeError when concatenating str and bytes (#1154).
1153- [bezierTools] Implemented cusp support and removed ``approximate_fallback``
1154  arg in ``calcQuadraticArcLength``. Added ``calcCubicArcLength`` (#1142).
1155
11563.21.2 (released 2018-01-08)
1157----------------------------
1158
1159- [varLib] Fixed merging PairPos Format1/2 with missing subtables (#1125).
1160
11613.21.1 (released 2018-01-03)
1162----------------------------
1163
1164- [feaLib] Allow mixed single/multiple substitutions (#612)
1165- Added missing ``*.afm`` test assets to MAINFEST.in (#1137).
1166- Fixed dumping ``SVG`` tables containing color palettes (#1124).
1167
11683.21.0 (released 2017-12-18)
1169----------------------------
1170
1171- [cmap] when compiling format6 subtable, don't assume gid0 is always called
1172  '.notdef' (1e42224).
1173- [ot] Allow decompiling fonts with bad Coverage format number (1aafae8).
1174- Change FontTools licence to MIT (#1127).
1175- [post] Prune extra names already in standard Mac set (df1e8c7).
1176- [subset] Delete empty SubrsIndex after subsetting (#994, #1118).
1177- [varLib] Don't share points in cvar by default, as it currently fails on
1178  some browsers (#1113).
1179- [afmLib] Make poor old afmLib work on python3.
1180
11813.20.1 (released 2017-11-22)
1182----------------------------
1183
1184- [unicodedata] Fixed issue with ``script`` and ``script_extension`` functions
1185  returning inconsistent short vs long names. They both return the short four-
1186  letter script codes now. Added ``script_name`` and ``script_code`` functions
1187  to look up the long human-readable script name from the script code, and
1188  viceversa (#1109, #1111).
1189
11903.20.0 (released 2017-11-21)
1191----------------------------
1192
1193- [unicodedata] Addded new module ``fontTools.unicodedata`` which exports the
1194  same interface as the built-in ``unicodedata`` module, with the addition of
1195  a few functions that are missing from the latter, such as ``script``,
1196  ``script_extension`` and ``block``. Added a ``MetaTools/buildUCD.py`` script
1197  to download and parse data files from the Unicode Character Database and
1198  generate python modules containing lists of ranges and property values.
1199- [feaLib] Added ``__str__`` method to all ``ast`` elements (delegates to the
1200  ``asFea`` method).
1201- [feaLib] ``Parser`` constructor now accepts a ``glyphNames`` iterable
1202  instead of ``glyphMap`` dict. The latter still works but with a pending
1203  deprecation warning (#1104).
1204- [bezierTools] Added arc length calculation functions originally from
1205  ``pens.perimeterPen`` module (#1101).
1206- [varLib] Started generating STAT table (8af4309). Right now it just reflects
1207  the axes, and even that with certain limitations:
1208  * AxisOrdering is set to the order axes are defined,
1209  * Name-table entries are not shared with fvar.
1210- [py23] Added backports for ``redirect_stdout`` and ``redirect_stderr``
1211  context managers (#1097).
1212- [Graphite] Fixed some round-trip bugs (#1093).

1220  Read the commit message 8b02b5a and issue #1030 for more details.
1221  NOTE: this change invalidates all the TTX files containing CFF2 tables
1222  that where dumped with previous verisons of fonttools.
1223  CFF2 Subr items can have values on the stack after the last operator, thus
1224  a ``CFF2Subr`` class was added to accommodate this (#1091).
1225- [_k_e_r_n] Fixed compilation of AAT kern version=1.0 tables (#1089, #1094)
1226- [ttLib] Added getBestCmap() convenience method to TTFont class and cmap table
1227  class that returns a preferred Unicode cmap subtable given a list of options
1228  (#1092).

1244----------------------------
1245
1246- [svgPathPen] Added an ``SVGPathPen`` that translates segment pen commands
1247  into SVG path descriptions. Copied from Tal Leming's ``ufo2svg.svgPathPen``
1248  https://github.com/typesupply/ufo2svg/blob/d69f992/Lib/ufo2svg/svgPathPen.py
1249- [reverseContourPen] Added ``ReverseContourPen``, a filter pen that draws
1250  contours with the winding direction reversed, while keeping the starting
1251  point (#1071).
1252- [filterPen] Added ``ContourFilterPen`` to manipulate contours as a whole
1253  rather than segment by segment.
1254- [arrayTools] Added ``Vector`` class to apply math operations on an array
1255  of numbers, and ``pairwise`` function to loop over pairs of items in an
1256  iterable.

1343- [varLib.interpolate_layout] Added ``mapped`` keyword argument to
1344  ``interpolate_layout`` to allow disabling avar mapping: if False (default),
1345  the location is mapped using the map element of the axes in designspace file;

1386- [varLib] Added support for building ``avar`` table, using the designspace
1387  ``<map>`` elements.
1388- [varLib] Removed unused ``build(..., axisMap)`` argument. Axis map should

1455  finding wrong contour order between different masters
1456- [varLib] designspace.load() now returns a dictionary, instead of a tuple,
1457  and supports <axes> element (#864); the 'masters' item was renamed 'sources',
1458  like the <sources> element in the designspace document
1459- [ttLib] Fixed issue with recalculating ``head`` modified timestamp when
1460  saving CFF fonts

1570   TrueType using the googlei18n/cu2qu module (#802)
1571
15723.4.0 (released 2016-12-21)
1573---------------------------
1574
1575-  [feaLib] Added support for generating FEA text from abstract syntax

1582---------------------------
1583
1584-  [setup] We no longer use versioneer.py to compute fonttools version
1585   from git metadata, as this has caused issues for some users (#767).
1586   Now we bump the version strings manually with a custom ``release``
1587   command of setup.py script.

1610-  [inspect] Made it compatible with both python2 and python3 (167ee60,
1611   #748). Thanks @pnemade
1612
16133.2.2 (released 2016-11-24)
1614---------------------------
1615
1616-  [varLib] Do not emit null axes in fvar (1bebcec). Thanks @robmck-ms

16223.2.1 (released 2016-11-03)
1623---------------------------
1624
1625-  [OS/2] fix checking ``fsSelection`` bits matching ``head.macStyle``
1626   bits
1627-  [varLib] added ``--build-HVAR`` option to generate ``HVAR`` table for
1628   fonts with TrueType outlines. For ``CFF2``, it is enabled by default.
1629
16303.2.0 (released 2016-11-02)
1631---------------------------
1632
1633-  [varLib] Improve support for OpenType 1.8 Variable Fonts:
1634-  Implement GDEF's VariationStore
1635-  Implement HVAR/VVAR tables
1636-  Partial support for loading MutatorMath .designspace files with
1637   varLib.designspace module
1638-  Add varLib.models with Variation fonts interpolation models
1639-  Implement GSUB/GPOS FeatureVariations
1640-  Initial support for interpolating and merging OpenType Layout tables
1641   (see ``varLib.interpolate_layout`` and ``varLib.merger`` modules)
1642-  [API change] Change version to be an integer instead of a float in
1643   XML output for GSUB, GPOS, GDEF, MATH, BASE, JSTF, HVAR, VVAR, feat,
1644   hhea and vhea tables. Scripts that set the Version for those to 1.0
1645   or other float values also need fixing. A warning is emitted when
1646   code or XML needs fix.
1647-  several bug fixes to the cffLib module, contributed by Adobe's
1648   @readroberts
1649-  The XML output for CFF table now has a 'major' and 'minor' elements
1650   for specifying whether it's version 1.0 or 2.0 (support for CFF2 is
1651   coming soon)
1652-  [setup.py] remove undocumented/deprecated ``extra_path`` Distutils
1653   argument. This means that we no longer create a "FontTools" subfolder
1654   in site-packages containing the actual fontTools package, as well as
1655   the standalone xmlWriter and sstruct modules. The latter modules are
1656   also deprecated, and scheduled for removal in upcoming releases.
1657   Please change your import statements to point to from fontTools.misc
1658   import xmlWriter and from fontTools.misc import sstruct.
1659-  [scripts] Add a 'fonttools' command-line tool that simply runs
1660   ``fontTools.*`` sub-modules: e.g. ``fonttools ttx``,
1661   ``fonttools subset``, etc.
1662-  [hmtx/vmts] Read advance width/heights as unsigned short (uint16);
1663   automatically round float values to integers.
1664-  [ttLib/xmlWriter] add 'newlinestr=None' keyword argument to
1665   ``TTFont.saveXML`` for overriding os-specific line endings (passed on
1666   to ``XMLWriter`` instances).
1667-  [versioning] Use versioneer instead of ``setuptools_scm`` to
1668   dynamically load version info from a git checkout at import time.
1669-  [feaLib] Support backslash-prefixed glyph names.
1670
16713.1.2 (released 2016-09-27)
1672---------------------------
1673
1674-  restore Makefile as an alternative way to build/check/install
1675-  README.md: update instructions for installing package from source,
1676   and for running test suite
1677-  NEWS: Change log was out of sync with tagged release
1678
16793.1.1 (released 2016-09-27)
1680---------------------------
1681
1682-  Fix ``ttLibVersion`` attribute in TTX files still showing '3.0'
1683   instead of '3.1'.
1684-  Use ``setuptools_scm`` to manage package versions.
1685
16863.1.0 (released 2016-09-26)
1687---------------------------
1688
1689-  [feaLib] New library to parse and compile Adobe FDK OpenType Feature
1690   files.

1697   to draw to Type 2 Charstrings (CFF); add areaPen and perimeterPen.
1698-  [ttLib.tables] Implement 'meta' and 'trak' tables.
1699-  [ttx] Add --flavor option for compiling to 'woff' or 'woff2'; add
1700   ``--with-zopfli`` option to use Zopfli to compress WOFF 1.0 fonts.
1701-  [subset] Support subsetting 'COLR'/'CPAL' and 'CBDT'/'CBLC' color
1702   fonts tables, and 'gvar' table for variation fonts.
1703-  [Snippets] Add ``symfont.py``, for symbolic font statistics analysis;
1704   interpolatable.py, a preliminary script for detecting interpolation
1705   errors; ``{merge,dump}_woff_metadata.py``.
1706-  [classifyTools] Helpers to classify things into classes.
1707-  [CI] Run tests on Windows, Linux and macOS using Appveyor and Travis
1708   CI; check unit test coverage with Coverage.py/Coveralls; automatic
1709   deployment to PyPI on tags.
1710-  [loggingTools] Use Python built-in logging module to print messages.
1711-  [py23] Make round() behave like Python 3 built-in round(); define
1712   round2() and round3().

17622.3 (released 2009-11-08)
1763-------------------------
1764
1765-  TrueType Collection (TTC) support
1766-  Python 2.6 support
1767-  Update Unicode data to 5.2.0
1768-  Couple of bug fixes
1769
17702.2 (released 2008-05-18)
1771-------------------------
1772
1773-  ClearType support
1774-  cmap format 1 support
1775-  PFA font support
1776-  Switched from Numeric to numpy
1777-  Update Unicode data to 5.1.0
1778-  Update AGLFN data to 1.6
1779-  Many bug fixes
1780
17812.1 (released 2008-01-28)
1782-------------------------
1783
1784-  Many years worth of fixes and features
1785
17862.0b2 (released 2002-??-??)
1787---------------------------
1788
1789-  Be "forgiving" when interpreting the maxp table version field:
1790   interpret any value as 1.0 if it's not 0.5. Fixes dumping of these
1791   GPL fonts: http://www.freebsd.org/cgi/pds.cgi?ports/chinese/wangttf
1792-  Fixed ttx -l: it turned out this part of the code didn't work with
1793   Python 2.2.1 and earlier. My bad to do most of my testing with a
1794   different version than I shipped TTX with :-(
1795-  Fixed bug in ClassDef format 1 subtable (Andreas Seidel bumped into
1796   this one).
1797
17982.0b1 (released 2002-09-10)
1799---------------------------
1800
1801-  Fixed embarrassing bug: the master checksum in the head table is now
1802   calculated correctly even on little-endian platforms (such as Intel).
1803-  Made the cmap format 4 compiler smarter: the binary data it creates
1804   is now more or less as compact as possible. TTX now makes more
1805   compact data than in any shipping font I've tested it with.
1806-  Dump glyph names as a separate "GlyphOrder" pseudo table as opposed
1807   to as part of the glyf table (obviously needed for CFF-OTF's).
1808-  Added proper support for the CFF table.
1809-  Don't barf on empty tables (questionable, but "there are font out
1810   there...")
1811-  When writing TT glyf data, align glyphs on 4-byte boundaries. This
1812   seems to be the current recommendation by MS. Also: don't barf on
1813   fonts which are already 4-byte aligned.
1814-  Windows installer contributed bu Adam Twardoch! Yay!
1815-  Changed the command line interface again, now by creating one new
1816   tool replacing the old ones: ttx It dumps and compiles, depending on
1817   input file types. The options have changed somewhat.
1818-  The -d option is back (output dir)
1819-  ttcompile's -i options is now called -m (as in "merge"), to avoid
1820   clash with dump's -i.
1821-  The -s option ("split tables") no longer creates a directory, but
1822   instead outputs a small .ttx file containing references to the
1823   individual table files. This is not a true link, it's a simple file
1824   name, and the referenced file should be in the same directory so
1825   ttcompile can find them.
1826-  compile no longer accepts a directory as input argument. Instead it
1827   can parse the new "mini-ttx" format as output by "ttx -s".
1828-  all arguments are input files
1829-  Renamed the command line programs and moved them to the Tools
1830   subdirectory. They are now installed by the setup.py install script.
1831-  Added OpenType support. BASE, GDEF, GPOS, GSUB and JSTF are (almost)
1832   fully supported. The XML output is not yet final, as I'm still
1833   considering to output certain subtables in a more human-friendly
1834   manner.
1835-  Fixed 'kern' table to correctly accept subtables it doesn't know
1836   about, as well as interpreting Apple's definition of the 'kern' table
1837   headers correctly.
1838-  Fixed bug where glyphnames were not calculated from 'cmap' if it was
1839   (one of the) first tables to be decompiled. More specifically: it
1840   cmap was the first to ask for a glyphID -> glyphName mapping.
1841-  Switched XML parsers: use expat instead of xmlproc. Should be faster.
1842-  Removed my UnicodeString object: I now require Python 2.0 or up,
1843   which has unicode support built in.
1844-  Removed assert in glyf table: redundant data at the end of the table
1845   is now ignored instead of raising an error. Should become a warning.
1846-  Fixed bug in hmtx/vmtx code that only occured if all advances were
1847   equal.
1848-  Fixed subtle bug in TT instruction disassembler.
1849-  Couple of fixes to the 'post' table.
1850-  Updated OS/2 table to latest spec.
1851
18521.0b1 (released 2001-08-10)
1853---------------------------
1854
1855-  Reorganized the command line interface for ttDump.py and
1856   ttCompile.py, they now behave more like "normal" command line tool,
1857   in that they accept multiple input files for batch processing.
1858-  ttDump.py and ttCompile.py don't silently override files anymore, but
1859   ask before doing so. Can be overridden by -f.
1860-  Added -d option to both ttDump.py and ttCompile.py.
1861-  Installation is now done with distutils. (Needs work for environments
1862   without compilers.)
1863-  Updated installation instructions.
1864-  Added some workarounds so as to handle certain buggy fonts more
1865   gracefully.
1866-  Updated Unicode table to Unicode 3.0 (Thanks Antoine!)
1867-  Included a Python script by Adam Twardoch that adds some useful stuff
1868   to the Windows registry.
1869-  Moved the project to SourceForge.
1870
18711.0a6 (released 2000-03-15)
1872---------------------------
1873
1874-  Big reorganization: made ttLib a subpackage of the new fontTools
1875   package, changed several module names. Called the entire suite
1876   "FontTools"
1877-  Added several submodules to fontTools, some new, some older.
1878-  Added experimental CFF/GPOS/GSUB support to ttLib, read-only (but XML
1879   dumping of GPOS/GSUB is for now disabled)
1880-  Fixed hdmx endian bug
1881-  Added -b option to ttCompile.py, it disables recalculation of
1882   bounding boxes, as requested by Werner Lemberg.
1883-  Renamed tt2xml.pt to ttDump.py and xml2tt.py to ttCompile.py
1884-  Use ".ttx" as file extension instead of ".xml".
1885-  TTX is now the name of the XML-based *format* for TT fonts, and not
1886   just an application.
1887
18881.0a5
1889-----
1890
1891Never released
1892
1893-  More tables supported: hdmx, vhea, vmtx
1894
18951.0a3 & 1.0a4
1896-------------
1897
1898Never released
1899
1900-  fixed most portability issues
1901-  retracted the "Euro_or_currency" change from 1.0a2: it was
1902   nonsense!
1903
19041.0a2 (released 1999-05-02)
1905---------------------------
1906
1907-  binary release for MacOS
1908-  genenates full FOND resources: including width table, PS font name
1909   info and kern table if applicable.
1910-  added cmap format 4 support. Extra: dumps Unicode char names as XML
1911   comments!
1912-  added cmap format 6 support
1913-  now accepts true type files starting with "true" (instead of just
1914   0x00010000 and "OTTO")
1915-  'glyf' table support is now complete: I added support for composite
1916   scale, xy-scale and two-by-two for the 'glyf' table. For now,
1917   component offset scale behaviour defaults to Apple-style. This only
1918   affects the (re)calculation of the glyph bounding box.
1919-  changed "Euro" to "Euro_or_currency" in the Standard Apple Glyph
1920   order list, since we cannot tell from the 'post' table which is
1921   meant. I should probably doublecheck with a Unicode encoding if
1922   available. (This does not affect the output!)
1923
1924Fixed bugs: - 'hhea' table is now recalculated correctly - fixed wrong
1925assumption about sfnt resource names
1926
19271.0a1 (released 1999-04-27)
1928---------------------------
1929
1930-  initial binary release for MacOS
