Changes to the LyX format since version 220 (LyX 1.2.0) was released.
=====================================================================
2002-08-02 Angus Leeming <leeming@lyx.org>
Added a boolean "preview" flag to InsetCommandParams.
Currently it is written only by InsetInclude, because only this
class can generate a preview of its contents.
The LyX file now contains:
\begin_inset Include \input{snapshot_t=40.tex}
+preview true
\end_inset
Earlier versions of LyX just swallow this extra token silently.
