A note on the new features:
 * The "This is a minor edit" checkbox is now available when you create a page or new section . It should say it would be not available when you create a page or new section, since it doesn't make sense to mark that action as minor

Other important new features:
 * ResourceLoader.
 * Gadgets extension. I would like to know if it will be enabled on Wikia

Some changes that may break things:
 * Monobook users: Be aware of some changes in the CSS code. For example, they're now applying selectors to div#footer instead of just #footer, so if you want to override some styles of it you should also use div#footer.
 * All skins: there's a new wrapping div for just the content (without the main header and categories): #mw-content-text. Be aware of CSS styles that only apply to immediate childrens of #bodyContent (#bodyContent > h2 for example) and the same for Oasis skin.
 * By default a configuration variable is enabled which would turn all  into  . That would make center-aligned tables into left-aligned tables with centered text. You should avoid align="center" and use style="margin:auto;" instead.
