Language packages indicate 3rd party translations, which miniBB authors can not control, since they are not polyglots. Version indicates miniBB release, when this package was first offered. Most of newest releases come with additional language variables, which are put at the end of each pack. If there are some mistakes or defects, feel free to edit your native pack and re-upload it for miniBB team. You will get whatever credit you want, incl. link to your project WWW page.
