We just released mozjpeg 2.1.
https://github.com/mozilla/mozjpeg/releases/tag/v2.1
We decided to release primarily in order to address issues with configuring
mozjpeg to produce baseline JPEGs while still making use of features like
trellis quantization.
Compatibility note: The "-baseline" option for cjpeg has been re-defined in
this release. If you've been using it (unlikely), you'll want to re-examine
your options.
