November 2006: - Include an enhancement by Pieter Eendebak for natbib.cfg (part of the documentation) March 2005: - Support for authauthor and autheditor fields in BibTeX data base. These fields serve to provide a consistent spelling of author names - Bugfix: When using multiple BibTeX data bases, they will be queried in the sequence given in the LaTeX source. This is important when some data bases define @STRINGs used in others. October 2004: - Bugfix: Gracefully handle spaces in citation commands with multiple arguments. Previous versions included the space in the key, which cased the search in the BibTeX data base to fail.
