- Update to 18.3.3
* In this release we have:
A memory leak fix in the etnaviv driver, better NEON assembly code in vc4 and
couple of stability improvements to the radeonsi driver. Another memory leak
affecting all gallium drivers have also been addressed.
* The time required to compile GLSL shaders with large amount of uniforms, such
as Godot, has been improved.
* GLX and swrast have also seen some improvements.
* On the Vulkan side, the ANV driver adjusted the number of images supported
for gen8 and earlier to 8, while for newer hardware it remains the same 64.
The RADV driver has seens a collection of stability improvements and fix for
the Vulkan version advertised in some corner cases.
* To top it all up, the meson build system has seen a steady amount of fixes:
the DSO version for the VDPAU drivers is now included, ICC compatibility
patches, opencl handling and relaxed handling when building osmesa.
