v2.0.1

This is a patch release containing the following fixes and minor enhancements:

PR #1303, Update the After Effects and Photoshop plug-ins to OCIO v2.
PR #1352, Fix a problem with allocation vars not being used for the legacy GPU processing path. This provides a new getOptimizedLegacyGPUProcessor call for developers to access the legacy GPU processing (although you should be using the new GPU processor anyway!) and deprecates the previous CreateLegacyShaderDesc method.
PR #1387, Fix an issue where the environment section of the config was not being validated correctly for vars without a default. This also introduces stricter rules for validation of this part of the config and prevents a possible crash affecting both v1 and v2.
PR #1394, After Effects and Photoshop plug-in build updates.
PR #1370, Fix a minor issue with how CDL ops are optimized.
PR #1365, Enable gcc -Wextra build flag and clean up the resulting warnings.
PR #1353, Re-enable support for negative stride values for packed and planar ImageDescs.
PR #1351, Improve C++ version detection and fix some compilation issues.
PR #1350, Fix and update 'setup_ocio' script.
PR #1339, Correct a typo in the OCIO_USER_CATEGORIES environment variable name.
PR #1338, Fix an issue with the RPATH that was impacting the Python binding.
PR #1336, Improvements to cmake scripts and remove the OCIO_ADD_EXTRA_BUILTINS flag.
PR #1306, Correct the minimum GLSL version specified in some places (is now GPU_LANGUAGE_GLSL_1_2).

v2.0.0

This is the official release of OpenColorIO v2! The noteworthy changes relative to v2.0.0rc1 are:

PR #1291, Fixed a bug in the single-pixel applyRGB call.
PR #1281, Additional ACES Built-in Transforms -- The built-ins now include all transforms identified by the config working group for the initial ACES config, including all of the ACES Output Transforms.
PR #1280, Add to Python binding Uniform_Float3 and setStrictParsingEnabled.
PR #1277, Fixed pybind issue to allow children of Transform class to have the correct type.
PR #1275, Restructure PyOpenColorIO -- Completed PyGpuShaderDesc and moved declarations. Fixed a number of issues with the Python documentation.
PR #1274, Added lots of new Python unit tests, adjusted a few bindings as a result. Reserved some enums for future work.
PR #1272, Avoid NaN values during Lut1D composition.
PR #1271, Python dynamic property fixes and added unit tests. Warn if more than one property is active.
PR #1270, Modify Python LogCameraTransform and FixedFunctionTransform constructors to require arguments. Direct operator<< to Python repr rather than str.
PR #1268, Make shader textures available via the Python API.
PR #1267, Add constants for new roles to the API. Have parseColorSpaceFromString include inactive spaces. Modify ociocheck to warn if roles are missing, rather than error. Fix exception propagation issue from FileRules.
PR #1266, Use OIIO-provided CMake find module to fix build issue.

v2.0.0-rc1

This is the first release candidate for OCIO v2. The final release is about two weeks away, we request people test this thoroughly and help us find any issues. Here are the noteworthy changes relative to beta2:

PR #1241, Color Space Aliases -- It is now possible to define several alternate names for a color space, for example, a full name and an abbreviated name appropriate for use in image file paths. An optional "name" attribute was also added to the config.
PR #1220, App Helpers and Category improvements -- The App Helpers functions to ease use of the library have been moved into OCIO core. Also, the options for filtering color spaces based on category is now more powerful, implementing issue #1222.
PR #1197, New API Docs implementation -- This overhauls the way the API documentation for both C++ and Python are generated. Contributors now need to manually update the frozen Python .rst files and should review the issue for details.
PR #1249, Improved Python apply functions -- This fixed several Python applyRGB issues and the unit test for PyCPUProcessor now requires NumPy.
PR #1244, Improved version handling and config synonyms -- The parser will now throw if reading a minor version higher than current (i.e. a config version 2.1 or higher will now throw). This also fixed a bug when writing v1 configs that caused them to not load correctly. Several syntax enhancements requested related to view transforms were added: - The from/to_reference color space attributes are now written as from/to_scene_reference in v2 configs, although the old syntax is also supported. - The config also now has an attribute to identify the default view transform.
PR #1221, CDLTransform cleanup -- The code for reading and writing CDLs was refactored and the API changed so that they are written more like CLF and CTF files. The write method on Processor was moved to GroupTransform. The way CDL metadata is handled was made more consistent with CLF/CTF. Files with several CDLS (e.g. ccc) may now be loaded into a single GroupTransform.
PR #1245, Finish inversion of new look ops -- This complete the work on issue #1100, these operators all work in both forward and inverse direction.
PR #1251, Fix ACEScc and XYZ built-in transforms -- Addresses issues with several built-in transforms.
PR #1252, Misc fixes -- The ColorSpaceMenuHelpers code no longer warns on v1 configs. An edge case of using LegacyViewingPipeline with named transforms was addressed.
PR #1214, Minor file rules fixes.

v2.0.0-beta2

This is the second beta for OCIO v2. The release candidate is not far off, we request people test this thoroughly and help us find any issues. Here are the noteworthy changes relative to beta1:

PR #1189, Named Color Transforms -- It is now possible to include color transforms in a config separately from color spaces.
PR #1229, Data bypass fix -- Critical bug fix for an issue where conversions on data color spaces were sometimes not bypassed.
PR #1205, Remove dynamic properties from configs -- It is not possible to use dynamic properties in configs, configs are intended to be fixed representations.
PR #1228, Bump pybind11 required version to 2.6.1 -- Moving from 2.4.3 to 2.6.1 removes a dependency that was causing build issues.
PR #1204, Some API cleanup -- Capitalization change for three functions used for iterating over available LUT file formats.
PR #1208, Remove the 'unknown' shader language -- Minor cleanup of GPU renderer API.
