+ * Format incremented to 447: No changes in the file format
+ This format change was added to force the lyx2lyx conversion
+ for layout files using the new InsetArgument feature.
+ (see previous fileformat change 446)

+2012-11-19 Jürgen Spitzmüller <spitz@lyx.org>
+ * Format incremented to 446: Change of InsetArgument syntax.
+ InsetArgument now has a numeric identifier which determines
+ its position (in the LaTeX output):
+ \begin_inset Argument 1
+ ...
+ \end_inset
+ Pre-2.1 documents' arguments all get the number "999", and then
+ InsetArgument::updateBuffer() computes the correct number.
+ This is because lyx2lyx has no access to layouts and hence does
+ not know how many optional arguments a layout can have (if a command
+ has two optional and one mandatory arguments and only one optional
+ is actually given, the mandatory arg still must get number 3).

+ * Format incremented to 445: support for the URW Classico font,
