v1.5.1

release: v1.5.1

v1.5.0

• Fixed: Convert AVIF irot and imir into EXIF orientation when decoding an image, in #70. EXIF orientation has been preserved by the encoder since 1.4.2, which is when we started setting irot and imir. But if an AVIF image with non-default irot or imir values was converted to another format, its orientation would be lost.
• Fixed: pillow_avif.AvifImagePlugin.CHROMA_UPSAMPLING is now actually used when decoding an image, in #70.
• Fixed: TypeError when saving images with float frame durations, by @BlackSmith in #68) (merged from #71)
• Added: Python 3.13 free-thread mode support (experimental).
• CI: Update libavif to 1.2.0 (4eb0a40, 2025-03-05); publish wheels for python 3.13. See the table below for the current AVIF codec versions. Libraries whose versions have changed since the last pillow-avif-plugin release are bolded.
