OpenGL 27 4.5 is <strong>only</strong> available if requested at context creation 28 because compatibility contexts are not supported. 29 </p> 30 31 32 <h2>SHA256 checksums</h2> 33 <pre> 34 fb305eecfeec1fd771fdc96fff973c51871f7bd35fd2bd56cacc27b4b8823220 mesa-17.2.3.tar.gz 35 a0b0ec8f7b24dd044d7ab30a8c7e6d3767521e245f88d4ed5dd93315dc56f837 mesa-17.2.3.tar.xz 36 </pre> 37 38 39 <h2>New features</h2> 40 <p>None</p> 41 42 43 <h2>Bug fixes</h2> 44 45 <ul> 46 47 <li><a href="https://bugs.freedesktop.org/show_bug.cgi?id=101832">Bug 101832</a> - [PATCH][regression][bisect] Xorg fails to start after f50aa21456d82c8cb6fbaa565835f1acc1720a5d</li> 48 49 <li><a href="https://bugs.freedesktop.org/show_bug.cgi?id=102852">Bug 102852</a> - Scons: Support the new Scons 3.0.0</li> 50 51 <li><a href="https://bugs.freedesktop.org/show_bug.cgi?id=102940">Bug 102940</a> - Regression: Vulkan KMS rendering crashes since 17.2</li> 52 53 </ul> 54 55 56 <h2>Changes</h2> 57 58 <p>Alex Smith (1):</p> 59 <ul> 60 <li>radv: Add R16G16B16A16_SNORM fast clear support</li> 61 </ul> 62 63 <p>Bas Nieuwenhuizen (2):</p> 64 <ul> 65 <li>nir/spirv: Allow loop breaks in a switch body.</li> 66 <li>radv: Only set the MTYPE flags on GFX9+.</li> 67 </ul> 68 69 <p>Ben Crocker (4):</p> 70 <ul> 71 <li>gallivm: fix typo in debug_printf message</li> 72 <li>gallivm: allow additional llc options</li> 73 <li>gallivm/ppc64le: adjust VSX code generation control.</li> 74 <li>gallivm/ppc64le: allow environmental control of Altivec code generation</li> 75 </ul> 76 77 <p>Daniel Stone (2):</p> 78 <ul> 79 <li>egl/wayland: Check queryImage return for wl_buffer</li> 80 <li>egl/wayland: Don't use dmabuf with no modifiers</li> 81 </ul> 82 83 <p>Dave Airlie (2):</p> 84 <ul> 85 <li>radv: emit fmuladd instead of fma to llvm.</li> 86 <li>radv: lower ffma in nir.</li> 87 </ul> 88 89 <p>Emil Velikov (6):</p> 90 <ul> 91 <li>cherry-ignore: add "anv: Remove unreachable cases from isl_format_for_size"</li> 92 <li>cherry-ignore: add "anv/wsi: Allocate enough memory for the entire image"</li> 93 <li>swr/rast: do not crash on NULL strings returned by getenv</li> 94 <li>wayland-drm: use a copy of the wayland_drm_callbacks struct</li> 95 <li>eglmesaext: add forward declaration for struct wl_buffers</li> 96 <li>Update version to 17.2.3</li> 97 </ul> 98 99 <p>Eric Engestrom (1):</p> 100 <ul> 101 <li>scons: use python3-compatible print()</li> 102 </ul> 103 104 <p>Ilia Mirkin (2):</p> 105 <ul> 106 <li>nv50/ir: fix 64-bit integer shifts</li> 107 <li>nv50,nvc0: fix push hint logic in presence of a start offset</li> 108 </ul> 109 110 <p>Jason Ekstrand (6):</p> 111 <ul> 112 <li>intel/compiler: Don't cmod propagate into a saturated operation</li> 113 <li>intel/compiler: Don't propagate cmod into integer multiplies</li> 114 <li>glsl/blob: Return false from ensure_can_read on overrun</li> 115 <li>glsl/blob: Return false from grow_to_fit if we've ever failed</li> 116 <li>nir/opcodes: Fix constant-folding of ufind_msb</li> 117 <li>nir: Get rid of the variable on vote intrinsics</li> 118 </ul> 119 120 <p>Juan A.
