WordPress have just announced the release of WordPress 2.0.5 [1], you can see the changes at the Trac page for the release [2].
It’s new release time. The latest in our venerable 2.0 series, which now counts over 1.2 million downloads, is available for download immediately [3], and we suggest everyone upgrade as this includes security fixes.
