What's New in This Release:
- Support for progressive JPEGs has been added (fixes a long standing "bug" of progressive JPEGs becoming non-progressive during optimization).
- New options --all-normal and --all-progressive for converting JPEGs to non-progressive and progressive.
- A new -S / --size option to set the target size for the output file.
