As Andrew Nacin said that for WordPress RC1, release candidates are the last stop before the final release. It means they are done and have no bugs to squash. But with millions of users, many server configurations and setups, and thousands of plugins and themes, it is still possible they can miss something.
Since Beta 1 came on Thanksgiving, RC1 on Christmas, and RC2 on New Year’s Day. They will not be waiting for another holiday for the final release, so if you have not tested WordPress 3.1 yet, now get ready to test it
If you are a developer and interested in testing the release candidate and if you find a bug, there are a few ways to let them know :
- Post it to the Alpha/Beta area in the support forums
- Report it to the wp-testers mailing list
- Join the development IRC channel and tell them live at irc.freenode.net #wordpress-dev
- File a bug ticket on the WordPress Trac
