WordPress 2.3 Beta 3, the third and final beta for WordPress 2.3, is now available. Many bugs have been fixed since the second beta, and we could use your help finding and fixing more bugs in preparation for the first Release Candidate due next Monday. The standard disclaimer for betas applies. Beta 3 is pre-release software that is still being tested.
WordPress 2.2.3 is a security and bug-fix release for the 2.2 series. Since this is a security release, we suggest you upgrade immediately. Two of the fixes are high priority.
