This is an ABI-compatible update for the 2.4.x series that
includes all fixes and enhancements since the 2.4.1 release.
With the 2.4.2 release, the "Preview" label is now removed from
the ACES 2 implementation. After extensive collaboration with the
ACES Output Transform working group, and our own testing, ACES 2
support in OCIO is now officially released. We will continue to
closely monitor your feedback on this new tech.
A large part of the work since the 2.4.1 release was an attempt
to optimize the ACES 2 algorithms. ACES 2 is still substantially
slower than ACES 1 on CPU and somewhat slower on GPU. But the
optimization efforts did yield a roughly 25% speedup over the
2.4.1 release, along with a simplification of the code. Special
thanks to Kevin Wheatley and Remi Achard for leading this work.
In conjunction with the 2.4.2 release, the OCIO ACES configs
working group has released the ACES 2.0 configs for OCIO. Special
thanks to Thomas Mansencal for leading this work. The configs are
not yet built into the library itself and may be downloaded from
this link.
Bug fixes and enhancements:
- PR #2127, ACES 2.0 Output Transform performance optimization
- PR #2112, Absolute paths not working through ConfigIOProxy
- PR #2128, Add missing setConfigIOProxy call to the Python API
- PR #2117, Fix metal backend's generated shaders with
float/int/constant array performance

paths

- apparently the 2.4.0 tarball for a moment had the version set to
2.5.0 when i grabbed it. now it was fixed down to 2.4.x again.
so the soversion is downgraded again to 2.4

- Update to 2.4.1
This is an ABI-compatible update for the 2.4.x series that
includes all fixes since the 2.4.0 release.
The ACES 2 implementation is still considered a Preview Release.
OCIO contributors are working closely with the ACES 2 Output
Transforms working group and a 2.4.2 release is planned for early
March to finalize the ACES 2 algorithm implementation. A preview
of the ACES 2 config files (compatible with OCIO 2.4.1) is
available here.
- Bug fixes and minor enhancements:
- PR #2068, Fix views/display sub-menus in OCIO Display app for
ACES 2 compatibility
- PR #2095, Add "DISPLAY - CIE-XYZ-D65_to_DisplayP3-HDR"
built-in transform
- PR #2104, Optimizer detects pair inverses before combining
multiple op pairs
- PR #2074, Text format (e.g., Iridas cube) parsing

writing CTFs
- PR #2078, Added more accurate DX11 HLSL shading language enum

- Update to 2.3.2
This is an ABI-compatible update for the 2.3.x series that
includes all fixes since the 2.3.1 release.
In particular, this release fixes two crashes:
Certain older (generally 7-12 year old) CPUs including Intel
x86-64 (Sandy Bridge and Ivy Bridge) and Intel Atom
(Goldmont/Apollo Lake) microarchitectures that support SSE 4.2
SIMD instructions but do not support the initial AVX set and
XSAVE, or other CPUs where the OS has disabled AVX and XSAVE
support, will crash when trying to evaluate a Lut1D or Lut3D in
OCIO libraries compiled with SSE enabled (which is the default).
More recent CPUs (e.g., those supporting AVX2 or higher) should
not be affected.
Users of the Linux Python bindings via PyPI will crash when
trying to use OCIO from within another application that has been
compiled with the new libstdc++ ABI, per the requirements of the
VFX Platform for CY2023 and CY2024.
Bug fixes and minor enhancements:
- PR #1935, Prevent trying to use AVX instructions on certain
CPUs that don't support them
- PR #1933, Add manylinux_2_28 Python wheels for compliance with
the current VFX Platform libstdc++ ABI
- PR #1929, Fix ssse3 detection typo
- PR #1921, Fix build break with custom PyString installs by
always using system include pystring.h
- PR #1924, Fix narrowing conversion error in unit test on
riscv64
- PR #1925, Enhance the ociochecklut command-line tool to print
the output after each step
- drop a95febc7.patch: fixed in update

- only build the documentation in the ocio_tools case:
- move BuildRequires into the %if
- explicitely disable doc building in the library build case
- A probably better fix for solving the build cycle. First build
will only build all the libraries, 2nd build the cmdline tools
- Do not depends on OpenImageIO, in order to break up a build
cycle (boo#1190237).
