MediaWiki 1.13.0 is now available [1].
Selected changes to the API since 1.12.0: * action=edit has been added. Note that $wgEnableWriteAPI = true; is required for this. * list=allimages and prop=categoryinfo have been added. * The blredirect, eiredirect and iuredirect (for list=backlinks, list=embeddedin and list=imageusage) have finally been implemented. Setting these parameters will list links through redirects as well. * Paging (i.e. limit and continue parameters) have been added to prop=links, prop=templatelinks, prop=langlinks, prop=extlinks, prop=categories and prop=images. These modules no longer return all results by default, but only the first 10 (like list= modules do). * Invalid titles no longer throw errors but are listed as invalid instead. * Invalid values for multivalue parameters now throw warnings instead of errors
For a full list of changes to the API, see the section "API changes in 1.13" in the MediaWiki 1.13.0 release notes [2].
