from being installed properly.
# Version 3.0.2 (May 17, 2021)
Patch release with miscellaneous bug/build fixes, including:
* Fix TimeCode.frame max value
* Don't impose C++14 on downstream projects
* Restore fix to macOS universal 2 build lost from #854
* Imath auto-build version defaults to v3.0.2
## Version 3.0.1 (April 1, 2021)
Major release with major build restructing, security improvements, and
new features:
* Restructuring:
- The IlmBase/PyIlmBase submodules have been separated into the
Imath project, now included by OpenEXR via a CMake submodule
dependency, fetched automatically via CMake's FetchContent if
necessary.
- The library is now called ``libOpenEXR`` (instead of
``libIlmImf``). No header files have been renamed, they retain
the ``Imf`` prefix.
- Symbol linkage visibility is limited to specific public symbols.
* Build improvements:
- No more simultaneous static/shared build option.
- Community-provided support for bazel.
* New Features:
- ID Manifest Attributes, as described in ["A Scheme for Storing
Object ID Manifests in OpenEXR
Images"](https://doi.org/10.1145/3233085.3233086), Peter Hillman,
DigiPro 18: Proceedings of the 8th Annual Digital Production
Symposium, August 2018.
- New program: exrcheck validates the contents of an EXR file.
* Changes:
- EXR files with no channels are no longer allowed.
- Hard limit on the size of deep tile sizes; tiles must be less than
2^30 pixels.
- Tiled DWAB files used STATIC_HUFFMAN compression.
- ``Int64`` and ``SInt64`` types are deprecated in favor of
``uint64_t`` and ``int64_t``.
- Header files have been pruned of extraneous ``#include``'s
("Include What You Use"), which may generate compiler errors in
application source code from undefined symbols or
partially-defined types. These can be resolved by identifying and
including the appropriate header.
