Release 1.2.4
=============

- Adding support for fractional tessellation of patches
- Adding a much needed API documention system based on Docutils RST markup
- Adding support for face-varying interpolation in GLSL APIs
- Adding varying data buffers to OsdMesh
- Adding accessors to the vertex buffers in OsdGlMesh
- Adding face-varying data to regression shapes
- Cleanup of common bicubic patch shader code (GLSL / HLSL) for portability 
  (ATI / OSX drivers)
- Fix FarVertexEditTablesFactory to insert properly vertex edit batches
  (fixes incorrect hierarchical hole in regression shape)
- Fix FarPatchMap quadtree to not drop top-level non-quad faces
- Fix Gregory patches bug with incorrect max-valence
- Fix FarPatchTables::GetNumFaces() and FarPatchTables::GetFaceVertices()
  functions to return the correct values
- Fix face indexing GLSL code (ptex works on non-quads again)
- Fix face-varying data splicing in FarMultiMeshFactory
- Fix ptex face indexing in FarMultiMeshFactory
- Fix glew #include to not break builds
- Fix Clang / ICC build failures with FarPatchTables 
- Fix build and example code to work with GFLW 3.0+
- Fix cmake to have ptex dynamically linked in OSX

----

Release 1.2.3
=============

- EvalLimit API refactor : the EvalContext now has dedicated structs to track all
  the vertex, varying and face-varying data streams. Also renamed some "buffers"
  into "tables" to maintain code consistency
- EvalLimit optimization : switch serial indexing to a quad-tree based search
- Adding Varying and Face-Varying data interpolation to EvalLimit
- Face-varying data bug fixes : making sure the data is carried around appropriately
  Fixes for OpenCL use with the new batching APIs
- GLSL general shader code cleanup & fixes for better portability
- GLSL Tranform Feedback initialization fix
- Critical fix for FarMultiMesh batching (indexing was incorrect)
- Fix osdutil CL implementation (protect #includes on systems with no OpenCL SDK
  installed)
- Fix face-varying interpolation on adaptive patches
- FarPatchTables : fix IsFeatureAdaptive() to return the correct answer
- Fix Far factories to handle the absence of face-varying data correctly.
- Many GLSL shader code style fixes which should help with ATI / OSX shader compiling

----

Release 1.2.2
=============

- Introducing the EvalLimit API : the Eval module aims at providing support for
  computational tasks that are not related to drawing the surfaces. The EvalLimit
  sub-module provides an API that enables client code to evaluate primitive variables
  on the limit surface.
- Osd<xxx>ComputeController : minor optimization. Added early exit to Refine method 
  to avoid unnecessary interop. 
- OsdGLDawContext : minor API change. Protecting some member variables and adding
  const accessors
- OsdError : minor API refactor, added Warning functions.
- Fix Ptex bug : prevent corner texel guttering code to from going into infinite 
  loops
- Adding the ability for a FarMeshFactory to construct patchTables starting from 
  'firstLevel' in uniform subdivision mode
- Consolidating the color coding of bicubic patch types through all our our code 
  examples (this is used mostly as a debugging tool)
- Fixing some MSVC++ build warnings
- Update to the outdated README.md
