Some drivers don't support all the features required in OpenGL 4.5. OpenGL 4.5 is <strong>only</strong> available if requested at context creation because compatibility contexts are not supported. </p> <h2>SHA256 checksums</h2> <pre> c902d8dc2540195bc570d88af1a8fd8a1774373660a27bb1d539551f46824bc1 mesa-17.2.1.tar.gz 77385d17827cff24a3bae134342234f2efe7f7f990e778109682571dbbc9ba1e mesa-17.2.1.tar.xz </pre> <h2>New features</h2> <p>None</p> <h2>Bug fixes</h2> <ul> <li><a href="https://bugs.freedesktop.org/show_bug.cgi?id=100613">Bug 100613</a> -
