## Version 3.2.2 (February 11, 2024)

Patch release that addresses
[CVE-2023-5841](https://takeonme.org/cves/CVE-2023-5841.html).

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.

This release also addresses:

* OSS-fuzz [66491](https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=66491)
Out-of-memory in openexr_exrcorecheck_fuzzer
* OSS-fuzz [66489](https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=66489)

* IlmImf: Added Pixar's new "slightly lossy" image compression
method. The new method, named PXR24, preserves HALF and
UINT data without loss, but FLOAT pixels are converted to
a 24-bit representation. PXR24 appears to compress
FLOAT depth buffers very well without losing much accuracy.

* Changed top-level LICENSE file to allow for other copyright
holders for individual files.

* IlmImf: TILED FILE FORMAT CHANGE. TiledOutputFile was
incorrectly interleaving channels and scanlines before
passing pixel data to a compressor. The lossless compressors
still work, but lossy compressors do not. Fix the bug by
interleaving channels and scanlines in tiled files in the
same way as ScanLineOutputFile does. Programs compiled with
the new version of IlmImf cannot read tiled images produced
with version 1.1.0. (Florian Kainz)

* IlmImf: OpenEXR now supports YCA (luminance/chroma/alpha)
images with subsampled chroma channels. When an image
is written with the RGBA convenience interface, selecting
WRITE_YCA instead of WRITE_RGBA causes the library to
convert the pixels to YCA format. If WRITE_Y is selected,
only luminance is stored in the file (for black and white
images). When an image file is read with the RGBA convenience
interface, YCA data are automatically converted back to RGBA.
