AcademySoftwareFoundation/openexr v3.2.0

on GitHub

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:

  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.

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