What's New is an index, not a publisher: every entry below links to the vendor's own release notes, which are the authoritative source. Entries are labelled where they are hand-curated sample data, pre-releases, or drawn from a secondary source such as a developer blog.

- **fixed** — Python API no longer unconditionally overrides PIL.Image.MAX_IMAGE_PIXELS when the caller did not explicitly set max_image_mpixels, allowing host applications to have their PIL limit settings respected
- **security** — Updated uv.lock to avoid pinning a vulnerable version of Pillow

- Fixed Python API unconditionally overriding ``PIL.Image.MAX_IMAGE_PIXELS``
  when the caller did not explicitly set ``max_image_mpixels``. Host
  applications (e.g. Paperless-NGX) that configure the PIL limit before
  invoking ``ocrmypdf.ocr()`` now have their setting respected. The CLI
  default of 250 megapixels is unchanged. {issue}`1665`
- Updated uv.lock to avoid pinning a vulnerable version of Pillow. {issue}`1666`
