WordPress 2.3.1 is now available. 2.3.1 is a bug-fix and security release for the 2.3 series.

2.3.1 fixes over twenty bugs. Some of the notable fixes are:

• Tagging support for Windows Live Writer
• Fixes for a login bug that affected those with a Blog Address different than
  their WordPress Address
• Faster taxonomy database queries, especially tag intersection queries
• Link importer fixes

Unfortunately, some security issues were found in 2.3. Janek Vind found an XSS problem that can be exploited if your php setup has register_globals enabled. For this reason, upgrading to 2.3.1 is advised.

Just updated my blog from previous version 2.2.3 to this version, thanks to Siew for the updates. I’m using the Maintenance Mode display on my blog when I’m doing the upgrading and it is a very good plug-in to have.
