By releasing RC1, we hope to avoid a follow up release (126.96.36.199). All code from WordPress 2.9.1 has been migrated to our codebase. Help us out – Download it and test it.
There is a “Release Candidates” under the WordPress download folder, here you will find all of the new component files, there is an alternative and complete install you can use.
Please help us make the final release the best it can be.
