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:

    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.
