### Added

- Added support for specifying in configs how to detect the images of a type
  instead of relying on global mime-type database. This is faster, more
  reliable, and works on systems like Windows out of the box.
- Give proper error messages when processors panic instead of waiting for
  results forever.
- Glycin can now be built with compiled-in (builtin) processors. In that case,
  loaders don't have to be available as separate binaries. While this mode
  doesn't provide sandboxing and extendability, it supports non-Linux systems
  like macOS and Windows. This mode will be used automatically when not built on
  Linux.
- heif: Add animation support for AVIF and HEIC files
- image-rs: The loaders and editors now use gufo 0.5. This brings support for
  more metadata extraction like key-value medata from PNGs and `<metadata>`
  entries from SVGs. For editing, this now supports changing the orientation of
  images with a broken Exif orientation tag.
- svg: Load XMP metadata

### Changed

- svg: Don't limit the size of elements in the SVG #279
