+GLSL optimizer Change Log
+=========================
+
+2015 05
+-------
+
+Fixes:
+
+* Fixes some cases of highp/mediump sampler sampling resulting in resulting temporaries wrongly being lowp.
+
+
+2015 04
+-------
+
+Goodies:
+* GLES2: support EXT_draw_instanced / gl_InstanceIDEXT.
+* Support gl_VertexID in GLSL < 1.30 when EXT_gpu_shader4 is used.
+
+Fixes:
+
+* Metal: fixed some bugs with translation of weird loops.
+
+
+2015 02
+-------
+
+Tweaks:
+
+* Texture LOD sampling functions on GLES2.0 now produce a wrapper call, that does approximation
+  (mip bias) on devices that don't support GL_EXT_shader_texture_lod.
+* Undefined precision integers on GLES now default to highp.
+
+
+2015 01
+-------
+
+Fixes:
+
+* Float literals are printed with 7 significant digits now.
+* Metal: GLSL mod() is properly translated into Metal's fmod().
+* Metal: Fixed some cases of reciprocal (1/x) printing missing half precision cast.
+* GLES3: textureOffset with a mipmap bias is printed correctly now.
+* Fixed a bug with loop inductor detection if the inductor was used before the loop for some things.
+* Fixed printing of int/float bitcast operations.
+* Improved precision determination of some constructs.
+
+
+2014 10
+-------
+
+Goodies:
+
+* Support for translating GLSL shaders into Apple Metal shading language.
+  Exactly same process; GLSL in (preferably ES3 variant), optimization passes, Metal out.
+  All uniforms currently will be put into one constant buffer.
+  Pass kGlslTargetMetal target to get Metal.
+* Shader reflection API. See glslopt_shader_get_* functions. Binding indices
+  are only automatically assigned on Metal now; on GL/ES targets the reflection API is only
+  useful to get list of inputs/uniforms, their names and types.
+* Improved dead code elimation: some cases of swizzled/masked assignments where same variable was on both sides
+  were not eliminated if that variable was totally unused later.
+* Merged with upstream Mesa, comes with new optimizations (min/max pruning, tree rebalancing, vector_insert lowering).
+
+Fixes:
+
+* sampler3D declarations were missing precision qualifier on GLES3.0.
+
+
+2014 09
+-------
+
+Goodies:
+
+* Supports GL_EXT_draw_buffers in ES2.0, for MRT.
+
+
+2014 08
+-------
+
+Goodies:
+
+* Supports GL_EXT_shader_framebuffer_fetch now, in both ES2.0 & 3.0.
+
+Fixes:
+
+* Fixed printing of infinities & NaNs.
+* Fixed vectorization pass in some cases going wrong on texture lookups.
+
+
+2014 06
+-------
+
+Goodies:
+
+* Optimization: split vectors with only some used components into scalars.
+
+Fixes:
+
+* Fixed more issues with for-loop printing.
+* Fixed printing of unsigned integer swizzled & constants.
+
+2014 03
+-------
+
+Fixes:
+
+* Fixed missing precision qualifier in some ES shaders (mostly due to expansion of ternary ?: check).
+
+2014 02
+-------
+
+Fixes:
+
+* Fixed vectorize pass introduced last month going wrong with dot products.
+
+2014 01
+-------
+
+Goodies:
+
+* Better optimization: vectorize assignments to individual vector channels.
+* More OpenGL ES 2.0 conformant printing of complex for-loops (loop inductions printed
+  as += or ++; loop initializers inside loop body).
+
+Fixes:
+
+* Fixed array assignments sometimes appearing in pre-GLSL1.20 versions, especially with
+  complex loops that couldn't be unrolled.
+* Fixed output of textureOffset and texelFetch.
+* Fixed error messages on MRT outputs on GL & GLES3 (now supports 4 MRTs).
+
+2013 12
+-------
+
+Goodies:
+
+* Optimized performance; was spending half of the time in stupid string code.
+* Added glslopt_shader_get_stats to get *very* approximate shader complexity stats.
+* Nicer printing of complicated for-loops.
+
+Fixes:
+
+* Fixed printing of struct initializers.
+
+
+2013 11
+-------
+
+Goodies:
+
+* Better optimizations: CSE; `A+(-B) => A-B`; `!A || !B => !(A && B)`.
+* Merged with upstream Mesa.
+
+Fixes:
+
+* Fixed location qualifiers, ES3.0 version printing, samplerCubeShadow sampling operations.
+
+
+2013 10
+-------
+
+Goodies:
+
+* Initial OpenGL ES 3.0 support
+* API to query shader input names; glslopt_shader_get_input_count and glslopt_shader_get_input_name
+
+Changes:
+
+* Xcode project files updated to Xcode 5
+
+Fixes:
+
+* VS2013 fixes
