The anime metadata plugin has finally been updated to support some major changes that went though a while ago to how metadata providers worked in Media Browser. The plugin has largely been re-written, and is now compatible with the improved customization options available in MBS, while also bringing a few new features and numerous bug fixes. The update should be available with the next server release.
Changes:
Missing and unaired episode support
Improved series identification with TVDB
Improved season metadata
Improved algorithm for selecting the correct series/season when converting between tvdb/anidb formats
Improved genre metadata
Links to AniDB and AniList

It is recommended that you put the anime metadata downloaders above the core providers, but place the anime image fetchers below the core fetchers.
