** Description changed:
[Impact]
+
+ A new upstream bugfix release is available. Release note diff compared
+ to 17.2.4:
+
+ Mesa 17.2.5 is now available.
+
+ In this release we have:
+
+ In Mesa Core a GL error related to the ARB_ES3_1_compatibility spec
+ noticed with the GFXBench 5 Aztec Ruins has been corrected.
+
+ The GLSL compiler is not giving a linker error for mismatching uniform
+ precision with GLSL ES 1.00 any more. This enables, specially, several
+ Android applications which violate this rule, like Forge of Empires,
+ for example.
+
+ The SPIR-V compiler has corrected an assert triggered when support for
+ the simple memory model was claimed.
+
+ NIR has also received a correction related with
+ gl_SubGroupG{e,t}MaskARB.
+
+ The Intel drivers, specially i965, have received several fixes,
+ including a plug for a memory leak and another one in the compiler to
+ avoid GPU hangs on Broxton.
+
+ The gallium i915g driver for Intel has also seen an important
+ correction.
+
+ AMD drivers, mostly radv, have also received several fixes, including a
+ correction for a DCC corruption that was visible with Rust, breaking an
+ endless loop in r600, avoiding a GPU hang with vulkan dota2 in VR mode
+ and a plug for a memory leak.
+
+ Broadcom's vc4 has gotten a fix to compile out some non-debug code that
+ shouldn't be there for the release build.
+
+ ----
+
+ Mesa 17.2.6 is now available.
+
+ In this release we have:
+
+ In Mesa Core we have included a correction to keep a program alive when
+ re-linking and prevent an use-after-free.
+
+ The GLSL compiler has received several fixes, including one to prevent
+ a SIGSEV when calling an undeclared subroutine in certain conditions
+ and another to mark the xfb buffers as active only if a variable uses
+ them.
+
+ The SPIR-V compiler has corrected a couple of issues involving the
+ usage of separate images and texture/samplers.
+
+ The Intel drivers include many new fixes, specially for i965. Several
+ are focused on improving SIMD32 and little-core. It also includes a fix
+ for a GPU hang which was detected while playing HW accelerated video
+ with mpv.
+
+ The AMD drivers have also received some care. radv has seen plugged 2
+ memory leaks while r600 has gotten a fix through reversing the tess
+ factor components for isolines.
+
+ The swr driver has corrected two performance regressions, one for the
+ avx512 platforms and the other for the avx/avx2 platforms.
+
+ In the ddebug gallium driver we have a fix for an use-after-free.
+
+ On the EGL side, the Wayland platform of the the DRI2 drivers has
+ received a fix to prevent crashing in ancient systems.
+
+ GLX has also received corrections to prevent a couple of errors when
+ creating and binding a context in DRI3 and DRISW, respectively.
+
+ From build and integration point of view, we have added some few more
+ fixes, including one to allow building libglvnd when EGL is present but
+ not GLX, another to enable building targets which don't need X11, such
+ as omx and va, when XCB is not present, and another one to be able to
+ specify the prefix installation for the OpenCL icd file.
+
+ ----
+
+ Mesa 17.2.7 is now available.
+
+ In this release we have:
+
+ The current queue consists of a variety of fixes, with a sizeable hunk in the
+ shared GLSL codebase.
+
+ Whereas for individual drivers - i965 has a crash fix for when playing various
+ Valve games, r600 and nouveau have tweaks in their compiler backends. Fast
+ clears on radeonsi and RADV are better now, while the VAAPI encoding is
playing
+ nicely with GStreamer.
+
+ The WGL state tracker and SWR driver have also seen minor improvements.
+
+ To top of up - Mesa should build fine with the latest glibc 2.17.
+
+ ----
+
+ Mesa 17.2.8 is now available.
+
+ In this release we have:
+
+ The SPIR-V compiler has seen corrected a possible SEGFAULT.
+
+ The Intel i965 driver includes a correction for Haswell involving
+ doubles management.
+
+ The AMD drivers have also received some fixes. A couple have gone for
+ radv and radeon's VCE while r600 has seen corrected some glitches
+ detected with This War of Mine.
+
+ Gallium has also received a patch fixing a problem affecting the VMware
+ driver and the st/nine state tracker.
+
+ The endianness detection in Windows platform has been corrected to
+ default to little endian.
+
+ Finally, the X11 driver has been improved to notify properly a mesa
+ warning rather than using fprintf.
[Test case]
+ Test typical use cases on the most common hw/driver combinations:
+ intel/i965
+ nvidia/nouveau
+ radeon/radeonsi
[Regression potential]
+
+
+ These releases are tested against compliance, bugfix releases in particular
have minimal risk of regressing anything major at least.
