The API has long had difficulty in reporting the redirects to a title: the best that could be done was to use list=backlinks&blfilterredir=redirects, but that has issues if the redirect has additional wikilinks in the non-redirect content (e.g. bug 57057[1]). It also had issues with file and category redirects (e.g. bug 27621[2]).

With the merge of Gerrit change 104764,[3] the API has a new prop=redirects to query the redirects table directly. There is also a new list=allredirects, corresponding to existing modules such as list=alllinks. This should be deployed to WMF sites with 1.23wmf16.[4]

In addition, since Gerrit change 105829 (deployed with 1.23wmf10[4]) file and category redirects will no longer show up when using list=imageusage or list=categorymembers, unless the target file or category is also included in the non-redirect content. They will be reported in list=backlinks instead.
