Minified 1.1 is a long overdue maintenance release. Most importantly, it solves issues with 'swallowed' exceptions in promise handlers. They will now be reported. Unfortunately, the new promise implementation is slightly incompatible with the earlier releases.
Please read the release notes for details.
Minified 1.1 is also the first release that breaks the 4kB/8kB barrier. That's mostly caused by the new promise implementations.
