Release Notes: 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.
Release Notes: Safer temp file handling (if mkstemps() is available, and a patch to make "quiet mode" (-q) be quiet.
Release Notes: The -T/--threshold option was added to set the minimum optimization gain needed before a file is optimized. The default is to optimize if gain is even just one byte. Some minor fixes were also done.
Release Notes: Additional support was added for IPTC and ICC markers. Minor fixes were made.
