0.3 (09/03/2016)

A major internals refactor has taken place in this release, there are a number of breaking changes:

  • The Image class is now immutable. Previously, “resize” and “crop” operations altered the image in-place but now they now always return a new image leaving the original untouched.
  • There are now multiple Image classes. Each one represents possible state the image can be in (eg, in a file, loaded in Pillow, etc). Operations can return an image in a different class to what the operation was performed on.
  • The “backends” have been renamed to “plugins”.
  • A new registry module has been added which can be used for registering new plugins and operations.
  • The “original_format” attribute has been deprecated.

Other changes in this release:

  • Added auto_orient operation

  • Dropped Python 2.6 and 3.2 support
  • Formats now detected using images header instead of extension
