I tried to see the new strings in Moodle 2.1dev but I can't load them. The parameter $thisversion = '2.0' is hard coded in the file moodle/admin/langimport.php

I don't know if the language packs for 2.1 are created by AMOS? They should be created because the translaters should be able to see their current strings in Moodle 2.1dev and not only the strings for 2.0
