v3.2.2

Patch release that addresses CVE-2023-5841.

Note that this bug is present in the C++ API (since v3.1.0), although
it is in a routine that is predominantly used for development and
testing. It is not likely to appear in production code.

• Fix various compiler warnings
• Pkg-config generation is now on by default for all systems, including Windows

See CHANGES.md for details.

v3.2.0

Minor release with several additions, changes and improvements:

• Zip compression via libdeflate

  As of OpenEXR release v3.2, OpenEXR depends on libdeflate for DEFLATE-based compression. Previous OpenEXR releases relied on zlib. Builds of OpenEXR can choose either an libdeflate installation, or CMake can auto-fetch the source and build it internally. The internal build is linked statically, so no extra shared object is produced.

  See website/install.rst for more details.

• New camdkit/camdkit-enabled standard attributes

  These changes bring to OpenEXR new standard optional attributes that were discussed in the SMPTE Rapid Industry Solutions On-Set Virtual Production Initiative). Additionally, some useful attributes from the SMPTE ACES Container File Layout standard, SMPTE ST 2065-4:2023, have been included as well. The new attributes are:

  Support automated editorial workflow:

  • reelName
  • imageCounter
  • ascFramingDecisionList

  Support forensics:

  • cameraMake
  • cameraModel
  • cameraSerialNumber
  • cameraFirmware
  • cameraUuid
  • cameraLabel
  • lensMake
  • lensModel
  • lensSerialNumber
  • lensFirmware
  • cameraColorBalance

  Support pickup shots:

  • shutterAngle
  • cameraCCTSetting
  • cameraTintSetting

  Support metadata-driven match move:

  • sensorCenterOffset
  • sensorOverallDimensions
  • sensorPhotositePitch
  • sensorAcquisitionRectangle
  • nominalFocalLength
  • effectiveFocalLength
  • pinholeFocalLength
  • entrancePupilOffset
  • tStop (complementing existing aperture)

  Also, renderingTransform and lookTransform have been deprecated.

  See website/StandardAttributes.rst and PR #1383 for more details.

• Updated SO versioning policy

  This change adopts a policy of appending the MAJOR.MINOR.PATCH software release name to the SONAME to form the real name of the shared library.

  See website/install.rst and PR #1498 for more details.

• Python bindings & PyPI wheel

  Support for the OpenEXR python bindings have been formally adopted by the OpenEXR project.

• Miscellaneous improvements:

  • "docs" renamed to "website" (PR #1504)

  • Additional deep & multipart code examples (PR #1493
    and PR #1502)

  • Many small build/test fixes

  • bin tools man pages

  • Expanded test coverage

Specific OSS-fuzz issues addressed:

• OSS-fuzz 46459 Out-of-memory in openexr_exrcheck_fuzzer
• OSS-fuzz 46432 Heap-buffer-overflow in generic_unpack
• OSS-fuzz 46413 Integer-overflow in reconstruct_chunk_table
• OSS-fuzz 45718 Heap-double-free in Imf_3_1::RgbaInputFile::~RgbaInputFile
