OpenImageIO 2.2.14.0

Release 2.2.14 (1 May 2021) -- compared to 2.2.13

• JPEG: Improve reading of files with mildly corrupted headers. #2927
• TIFF: Support IOProxy for input. #2921
• BMP: Improve performance by eliminating wasteful per-scanline allocation
  and needless data copying. #2934
• Build/CI: Fix all the build_*.bash scripts to not use cmake --config flag,
  which was harmlessly ignored but is flagged as an error for CMake 3.20.
  #2931
• Build: More fixes related to supporting a wide range of OpenEXR versions,
  and making our exported cmake configs correctly transmit dependencies on
  OpenEXR include paths. #2935 #2941 #2942 #2947
• ImageBufAlgo::fillholes_pushpull: added logic to correctly set the spec's
  alpha_channel field when generating sub-images. #2939
• Python: MakeTxBumpWithSlopes enum value had been inadvertently omitted
  from the Python bindings. #2951

OpenImageIO 2.2.13.1

Release 2.2.13.1 (7 Apr 2021) -- compared to 2.2.13.0

(Build related fixes only)

• Fix build break when using gcc 10 (and some other modern gcc versions)
  but using C++11 compilation mode. #2930
• CMake: don't use --config inappropriately (CMake 3.20 was broken for
  several of our helper build scripts for building dependencies). #2931
• Be robust to OpenEXR 2.x installations where IlmBase and OpenEXR had
  separate sets of config files in different subdirectories. #2935

OpenImageIO 2.2.13.0

Release 2.2.13 (1 Apr 2021) -- compared to 2.2.12

• Get ready for upcoming Imath/OpenEXR 3.0 release. #2883 #2894 #2897
• GIF: Fix error checking for non-existant GIF files. #2886
• Fix crash related to ImageBuf:set_write_format() when used in conjunction
  with a file format that doesn't support per-channel data types. #2885
• Make RAW files handle Unicode filenames on Windows. #2888
• Make sure OIIO builds cleanly with C++20. #2891
• BMP: Several bug fixes when reading an older (V1) variety of BMP files.
  #2899
• Targa: fix reading tga files with 0-sized thumbnails. #2903
• TIFF: fix reading of certain tiled TIFF files with the vertical image size
  is not a whole multiple of the tile size. #2895
• Avoid OpenColorIO v2 exception when color-conversion of single points (we
  didn't pass a correct stride, thinking that stride isn't used for a single
  point). #2911
• make_texture: When outputting to a 'half' data format file, clamp filtered
  values to the half range so large values don't inadvertently get converted
  to half 'infinite' values. #2892
• Improvements to ustring internals to ensure that no two ustrings ever end
  up with the same hash() value. #2870
• Fixes for compiler errors when compiling farmhash.h using C++11 mode with
  newer gcc (6+). #2914

OpenImageIO 2.2.12.0

Release 2.2.12 (1 Mar 2021) -- compared to 2.2.11

• Bug fix: Improve parsing of XMP records in metadata: more correct handling
  of lists/sequences, better inference of types that look like int or float
  (rather than forcing unknown fields into strings), fixed bugs in parsing
  rational values. #2865
• Bug fix: Fix loading PSB files with cinf tags. #2877
• Build: Improvements to building or linking static libraries. #2854
• Build: Change default STOP_ON_WARNING to OFF for release branches
  (including this one) so that small change in compiler warnings after our
  release don't break anybody's builds. (Though we still stop on warnings
  for CI builds). #2861
• Build: More clear warnings about using OpenVDB 8+ when building for C++11,
  because OpenVDB 8 requires C++14 or higher. #2860
• Build: The pkgconfig OpenImageIO.pc was specifying the include path
  incorrectly. #2869
• Build: More gracefully handle building against a custom Imath/OpenEXR even
  when another exists in the system area. #2876
• Build: Minor fixes to build cleanly against the upcoming Imath 3.0. #2878
• Dev: hash.h: Make many of the hash functions constexpr. #2843
• Dev: Better unit tests to verify correctness and stability over time of
  the hash functions. #2853
• Dev: unordered_map_concurrent.h: New methods find_or_insert, nobin_mask().
  #2867
• CI: Speed up CI builds by not building OpenEXR example programes. #2857
• CI: Speed up CI by using GitHub 'cache' actions + ccache. #2859
• CI: Separate stages (setup, deps, build, test) into separate GHA "steps"
  for better logging and understanding of the timing and performance. #2862
• CI: Now actively testing libheif in Linux CI. #2866
• CI: Remove the last vestiges of Travis-CI, which we no longer use. #2871
• CI: For failed tests, add CMake cache and log part of the saved artifacts.
• PSA: Avoid libheif 1.10 on Mac, it is broken. Libheif 1.11 is fine.

OpenImageIO 2.2.11.1

• Fix build break against Qt 5.15.2 (deprecated enum). #2852

Emergency patch, because nearly simultaneously with this morning's release of 2.2.11.0, newly pushed ASWF Docker containers for VFX Platform 2021 seem to have updated to a slightly newer Qt that marked an old enum we used as deprecated.

OpenImageIO 2.2.11.0

Release 2.2.11 (1 Feb 2021) -- compared to 2.2.10

• Enabled AVIF decoding of heic files (requires libheif >= 1.7 and for it
  to have been built with an AV1 encoder/decoder). #2811 #2812 #2814 #2818
• oiiotool --help now prints the OCIO version (where it prints the config
  file and known color space). #2849
• Bug fix: ImageBufAlgo::ociolook() and ociofiletransform() internally
  reversed the order of their inverse and unpremult arguments, making it
  hard to select the inverse transformation. #2844
• Fix memory leak during decoding of some invalid Exif blocks. #2824
• Build: Fixed warnings when building against python 2.x. #2815
• Build: No longer directly link against python libraries when unnecessary.
  #2807
• Build: Better finding of OpenJpeg 2.4. #2829
• Build: On Windows, fix some linkage problems by changing the pybind11
  bindings to make a CMake "shared" library rather than "module". Sounds
  wrong, but seems to work. We will reverse if this causes problems. #2830
• Build: On Mac, libheif 1.10 is very broken. Don't use that version. #2847
• Build: Fix build break against changes coming in future libtiff, where it
  is changing from some libtiff-defined integer types to the equivalent
  stdint.h types. #2848
• Build: Some final touches to prepare for release of OpenColor 2.0. #2849
• Build: Fixes to support the libraw 202101 snapshot (their in-progress
  0.21.0). #2850
• CI: Got Windows CI fully working, bit by bit. #2796 #2805 #2821 #2826
  #2834 #2835 #2836 #2840
• Dev: Some internal rearrangement of span.h and string_view.h (that should
  not break source or ABI compatibility). std::size() and std::ssize()
  should work with OIIO::span and OIIO::string_view now. #2827
• Dev: ustring internals now have a way to ask for the list of ustrings
  whose hashses collided. #2786
• Dev: New Filesystem::generic_filepath() returnss a filepath in generic
  format (not OS specific). #2819
• Dev: ArgParse::abort() lets the response to a command line argument signal
  that no further arguments should be parsed. #2820
• Dev: In oiioversion.h, added macros OIIO_VERSION_GREATER_EQUAL and
  OIIO_VERSION_LESS. #2831
• Dev: In platform.h, added macro OIIO_INLINE_CONSTEXPR, which is equivalent
  to inline constexpr for C++17, but just constexpr for C++ <= 14. #2832

OpenImageIO 2.2.10.1

Release 2.2.10.1 (7 Jan 2021) -- compared to 2.2.10.0

• Fix build break against OpenColorIO v2.0 RC1. #2817

OpenImageIO v2.2.10.0

Happy New Year!

I have tagged Release-2.2.10.0 and moved the "release" branch marker to this location. This is the latest supported stable release that is guaranteed to be API, ABI, and link backwards-compatible with prior 2.2.x releases.

The tag "v2.2.10.0" has also been added. In 2021, we will be transitioning to this more commonly used tag nomenclature. For the rest of the 2.2 releases, we will issue both old and new tag styles for each release, to give people time to transition any scripts that assume a particular release tag nomenclature. We will also change the release branch development points from RB-x.y to dev-x.y, which I think is more clear about its intent than our nonstandard "RB".

Release 2.2.8 (1 Nov 2020) -- compared to 2.2.7

• Fix that ImageBuf images backed by ImageCache, could hold an outdated copy
  of the image if it was in the imagecache once, then changed on disk. #2696
• Fix stack overflow crash in IBA::colorconvert of unusually wide images.
  #2716
• Fix boost linkage problem on Windows. #2727

  #2733
• Fix ImageCache bug: add_tile/get_tile not properly honoring when

  always adding alpha; more efficient by skipping alpha premultiplication
  when it's unnecessary; now can read animated WebP images as multi-subimage
  files. #2730
• Docs: ImageInput chapter now has an example of reading image data into
  separate per-channel buffers. #2756
• Fixes to build against recent changes in OpenColorIO v2 master. #2765
