OpenGL 274.5 is <strong>only</strong> available if requested at context creation 28because compatibility contexts are not supported. 29</p> 30 31 32<h2>SHA256 checksums</h2> 33<pre> 34a9ed76702ffb14ad674ad48899f5c8c7e3a0f987911878a5dfdc4117dce5b415 mesa-17.2.6.tar.gz 356ad85224620330be26ab68c8fc78381b12b38b610ade2db8716b38faaa8f30de mesa-17.2.6.tar.xz 36</pre> 37 38 39<h2>New features</h2> 40<p>None</p> 41 42 43<h2>Bug fixes</h2> 44<ul> 45 46<li><a href="https://bugs.freedesktop.org/show_bug.cgi?id=100438">Bug 100438</a> -
