This version fixes a bug affecting only v3.0.4 where autoregeneration was always disabled when running Jekyll locally. This feature is a huge reason why Jekyll (or any static site generator, for that matter) is a joy to use. Sorry for the regression!
If you’re using GitHub Pages, you can follow the progress of the upgrade on the github/pages-gem repo.
As always, our history doc has links to the pull requests and issues associated with the release for your perusal.
We’re looking forward to the upcoming release of v3.2 which has some excellent goodies we think you’ll love.
Happy Jekylling!
