Saw this on WordPress admin dashboard this morning, WordPress 2.0.5 RC1 is out, but not open to public yet. This isn’t an official release, according to Dougal, WordPress 2.0.5 had change from Beta to Release Candidate, mean that soon it will release to the public.
It’s been almost three months since WordPress 2.0.4 released, the development seem like stopped for quite a long time, i guess most probably is because the team is busy with bbPress, a bulletin board system developed by WordPress team.
For those who want to try out the nightly build, you may join the WP Testers mailing list to get the download link, or you may go WordPress Trac site to have a look on what is new in the next release.
