WordPress 2.0.7 has just been released. It fixes a security hole which allowed to read the WordPress database via the file
wp-trackback.php. Although the threat depends on special circumstances and does not apply to all WordPress sites, it is highly recommended to update as soon as possible.
On a related note, there’s a new version of the Advanced Search plugin available. An error with category filtering on blogs with only one author reported by cj has been fixed in the new version. Also, there is now an Italian translation thanks to Andrea Barbieri.
The plugin is as always available from its home page. Have fun with the new version and let me know how you like it. Also, please help out with translations, and report bugs as well as improvement ideas!
Update: There was still another bug occuring on blogs with several authors of which only one actually has posts. The problem was fixed and the download for 0.5 was updated. Thanks to solemnchaos for the hint.
