+ * format incremented to 257: Caption styles have been replaced by
+ InsetCaption. This is at the same time also a layout file format
+ change to format 3. layout2layout removes caption layouts from old
+ styles.
+ Note that InsetCaption did exist before this format, but was never
+ used. Old files containing do nevertheless still work.
+ Of course users can still define a Caption style in layout files,
+ but the special treatment in LyX is gone (apart from the sensitive
+ label property).
