Hello,
I think we should start to maintain older versions of the API. I have
therefore added a new page on MediaWiki wiki:
<http://www.mediawiki.org/wiki/API:Backporting>. I have started by
adding fixed bugs from RELEASE-NOTES to the page. I will probably
start the backporting once I have time to find out how subversion's
merge functions work. Feel free to add and remove items to that page
or to start backporting yourself.
