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.
-

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:
