Hello; The Slovenian dictionary we are carrying in http://sl.openoffice.org will eventually be removed due to restrictive licensing.
I updated the Slovenian dictionary using the one on this site: http://www.tezaver.si/ (which appears to be an updated version of the one we carry). I don't speak slovenian so I can't test it beyond noticing that the file can be fetched and unzipped. The change should probably be merged to 3.4.1 upon successful testing. regards, Pedro.
