-----------------------
2011-12-18 Georg Baum <Georg.Baum@post.rwth-aachen.de>
* Format incremented to 421 (r40522)
The caption flag of longtable rows is no longer exclusive to the head
and foot flags, since captions can occur in any of the two heads and
two foots. Before, captions were implicitly in head or firsthead.
For Docbook and XHTML output the caption flag "wins" over head/foot.
2011-12-12 Julien Rioux <jrioux@lyx.org>
* Format incremented to 420 (r40484)
New buffer param \biblio_style to specify a document-wide
