WordPress 3.0.1 Release Candidate was just tagged and released. You can use Peter Westwood’s Beta Tester Plugin and use “Point Release Nightlies” to upgrade from WordPress 3.0 to the new release candidate.
WordPress 3.0.1 includes several bugfixes. Please consult the changelog on Trac for details on what has changed in this release.
The third release candidate (RC3) for WordPress 3.0 is now available. This will most likely be the last release candidate before WordPress 3.0 is released at some point next week. So if you are the adventurous kind and would like to contribute to WordPress, then download the release candidate here and provide your feedback.
What’s an RC? An RC comes after beta and before the final launch. It means we think we’ve got everything done: all features finished, all bugs squashed, and all potential issues addressed. But, then, with over 20 million people using WordPress with a wide variety of configurations and hosting setups, it’s entirely possible that we’ve missed something.
