We're in the home stretch now with our release of Review Board 2.0 RC 1.
Our fist release candidate was focused on squashing bugs, improving performance, and tweaking the usability of the product, in preparation for the final 2.0 release.
We've fine-tuned the diff viewer, cutting the time of some operations in half. We've also reduced the startup and response time for installations using extensions.
36 bugs were fixed since beta 3. These cover site installation, administration, the diff viewer, the new My Account page, and much more.
For extension writers, we've added a new hook for custom authentication backends, as well as a few more goodies to help keep your extension code tight and clean.
This release also includes the security fixes in the 1.7.22 release, and strengthens security and access logs in other areas.
If you're planning on upgrading to Review Board 2.0 when it's out, this would be a great time to test. We're hoping to release it soon, and your feedback will go a long way to ensuring this release is solid.
The full details are in the release notes.
