# Mesa 10.5.7 Release Notes / June 07, 2015

Mesa 10.5.7 is a bug fix release which fixes bugs found since the 10.5.6 release.

Mesa 10.5.7 implements the OpenGL 3.3 API, but the version reported by glGetString(GL_VERSION) or glGetIntegerv(GL_MAJOR_VERSION) / glGetIntegerv(GL_MINOR_VERSION) depends on the particular driver being used. Some drivers don't support all the features required in OpenGL 3.3. OpenGL 3.3 is only available if requested at context creation because compatibility contexts are not supported.

## Changes

Ben Widawsky (1):

Emil Velikov (4):

- docs: Add sha256sums for the 10.5.6 release
- get-pick-list.sh: Require explicit "10.5" for nominating stable patches
- cherry-ignore: add clover build fix not applicable for 10.5
- Update version to 10.5.7

Ilia Mirkin (18):

- nvc0/ir: set ftz when sources are floats, not just destinations
- nv50/ir: guess that the constant offset is the starting slot of array
- nvc0/ir: LOAD's can't be used for shader inputs
- nvc0: a geometry shader can have up to 1024 vertices output
- nv50/ir: avoid messing up arg1 of PFETCH
- nv30: don't leak fragprog consts
- nv30: avoid leaking render state and draw shaders
- nv30: fix clip plane uploads and enable changes
- nv30/draw: avoid leaving stale pointers in draw state
- nv30/draw: draw expects constbuf size in bytes, not vec4 units
- st/mesa: don't leak glsl_to_tgsi object on link failure
- glsl: avoid leaking linked gl_shader when there's a late linker error
- nv30/draw: fix indexed draws with swtnl path and a resource index buffer
- nv30/draw: only use the DMA1 object (GART) if the bo is not in VRAM
- nv30/draw: allocate vertex buffers in gart
- nv30/draw: switch varying hookup logic to know about texcoords
- nv30: falling back to draw path for edgeflag does no good
- nv30: avoid doing extra work on clear and hitting unexpected states

Jason Ekstrand (1):
