Introducing special page modular extensions, making the board vote special page the first of these.
- Moving common special page handling to SpecialPage.php
- Special page lists in the language classes are obsolete, replaced by the list in SpecialPage.php
- Special:Specialpages uses the standard page titles wfMsg(pagename) instead of the description list previously contained in the $wgSpecialPagesEn arrays
- Ability to add custom messages to the MessageCache. Overridable by the MediaWiki namespace.
- Moving board vote functionality from includes/SpecialBoardvote.php to extensions/BoardVote.php
