We've put out a new release of Review Board today, and it's a big one. We've fixed over 30 bugs, improved usability issues throughout the product, and made it much easier to configure the new per-repository incoming webhooks.
There are too many bug fixes to properly summarize, but they affect every user of Review Board. Browser compatibility fixes, repository fixes, API fixes, diff viewer fixes, you name it.
Review Board 2.0 introduced support for closing review requests referenced in pushed commits. This was available for GitHub, Bitbucket, and Google Code, and required providing these services with a webhook URL on Review Board.
If you're using this feature, make note: We've changed how it works, and your old hook URLs will no longer work.
If you want to update your hooks, or are setting them up for the first time, we've made this simple. The repository list in the administration UI will now show a "[Hooks]" link next to supported repositories. Click it and follow the easy instructions. (Note that your Review Board server must be to these services over the Internet for these hooks to work.)
