[Mediawiki-api] BREAKING CHANGES

[Roan Kattouw]

Here's a list of recent changes to the API that break the old interface. 
I'm supposed to announce them as soon as I make them, but I forgot about 
that lately. Here they are:

* meta=userinfo (r30128)
** Now accepts uiuser parameter to get information on other users
** Output format has changed
** Added uiprop=editcount (r30080)

* prop=imageinfo (r29981, r30066)
** iihistory parameter replaced by iilimit, iistart and iiend
** iiurlwidth and iiurlheight parameters added

In the future, I'll post breaking changes to this list immediately after 
I commit them (if I remember :D).
