+ \subsection{\pkg{xr}: Support citations to bibiographies in external documents}
+ 
+ The \pkg{xr} package can be used to reference labels in external
+ document, e.g., when a work is split over different documents that
+ need to be processed separateley, but has \cs{ref} or \cs{pageref}
+ links between each other. With this update \cs{cite} commands and
+ their cousins can now also reference bibliographies in external
+ documents, a feature that was originally made available by the package
+ \pkg{xcite} by Enrico Gregorio.
+ 
+ Note that for technical reasons \pkg{xr} doesn't work with
+ \pkg{hyperref}. Use \pkg{xr-hyper} instead if you need the latter
+ package.
