 - Improved listing of matching files with `list-files: shell` and `list-files: escape` options
-- Support local changes
-- Fixed retrieval of all changes via Github API when there are 100+ changes
 - Paths expressions are now evaluated using [picomatch](https://github.com/micromatch/picomatch) library
-- Support workflows triggered by any event
