There seems to be a problem with Bulgarian version of WordPress. Since version 3.0.5, there has been no updated to the bg.wordpress.org site. Acording to this site: http://translate.wordpress.org/projects/wp/dev – all files are 100% translated up until 3.2.0 version. But the version check inside WP does not show a localized version.
From what I understand there must be an updated archive in bg.wordpress.org. Can someone help me track who is responsible for this update. We are getting very out of date here
