-Changes to the LyX format since version 220 (LyX 1.2.0) was released.
-=====================================================================
+LyX file-format changes
+-----------------------
+
+2003-08-19 Michael Schmitt <michael.schmitt@teststep.org>
+
+ * attribute valignment="center" is replaced by valignment="middle"
+ for tabular columns and cells
+
+2003-07-28 José Matos <jamatos@lyx.org>
+
+ * \the_end is replaced with \end_document
+
+2003-07-28 José Matos <jamatos@lyx.org>
+
+ * \layout is replaced with \begin_layout
+
+2003-07-28 José Matos <jamatos@fep.up.pt>
+
+ Format bumped to 225
+
+ * All layouts finish now with \end_layout
+
+2003-06-04 Angus Leeming <leeming@lyx.org>
+
+ Format bumped to 224
+
+ * the storage of the external inset has been changed from
+
+ \begin_inset External XFig,"file.fig",""
+
+ \end_inset
+
+ to this
+
+ \begin_inset External
+ template XFig
+ filename file.fig
+ display <display_type>
+ lyxscale <scale>
+
+ \end_inset
+
+ throwing away the final arg (here "", more generally "<string>") that holds
+ the parameters variable.
+ Variables are output if present (filename) or different from the default
+ values (display, lyxscale).
+
+ Moreover, the RasterImage template has been scrapped. All RasterImage
+ external insets are now converted to Graphics insets.
+
+2003-05-20 Jürgen Spitzmüller <j.spitzmueller@gmx.de>
+
+ * Added new space insets:
+ \SpecialChar ~ is now \InsetSpace ~
+ ERT: "\ " could be converted to InsetSpace \<space>
+ ERT: "\," could be converted to InsetSpace \,
+
+2003-03-12 John Levon <levon@movementarian.org>
+
+ * Added \\end_header to signify the end of the header in a
+ more robust fashion.
+
+ * use_amsmath is now a tristate {0 = never, 1 = auto, 2 = always}
+
+2003-02-10 John Levon <levon@movementarian.org>
+
+ Format bumped to 222
+
+ Added \\tracking_changes 0|1 to the header.
+
+ Added \\author to the header. This can be present multiple
+ times, and is of the form :
+
+ \\author "Real Name" email@address.com
+
+ Added \\change_deleted, \\change_inserted. Each of these does not
+ span a paragraph, and is delimited by "\\change_unchanged\n". Both are
+ of the form :
+
+ \\change_inserted author time
+
+ where author is an integer ID reference into the author list in
+ the header, and time is time_t.
+
+2002-10-24 Rob Lahaye <lahaye@snu.ac.kr>
+
+ * insetgraphicsParams.h (scale): is now a float, not an unsigned int.
+
+2002-08-22 Rob Lahaye <lahaye@snu.ac.kr>
+
+New graphics dialog. With the removal of buttons in the dialog, also
+keywords in the graphics inset went. The following keywords do not
+exist anymore:
+ lyxsize_kind
+ lyxsize_type
+ lyxwidth
+ lyxheight
+ size_kind
+ size_type
+ rotate
+
+Only non-default values are saved to the lyx files. The defaults of the remaining
+keywords are;
+ filename <empty>
+ lyxscale 100
+ display default
+ scale 100
+ width <empty>
+ height <empty>
+ draft <off>
+ noUnzip <off>
+ BoundingBox <from file>
+ clip <off>
+ rotateAngle 0
+ rotateOrigin centerBaseline
+ subcaption <off>
+ subcaptionText <empty>
+ special <empty>
+
+The remaining keywords have sufficient overlap with the old ones for a
+smooth reading of the 1.2.x inset keywords in most common cases.
+
+Compatibility is certainly broken for the old lyxwidth/lyxheight keywords.
+They don't exist anymore and we can't translate them into a scaling value, while
+we're reading the graphics inset. The old lyxwidth/lyxheight keyword and its
+argument is ignored and lost.
+
+Only few compatibility issues are left for lyx2lyx:
+
+------------------------------------------------------------------------------
+old-token new-token remove
+------------------------------------------------------------------------------
+size_kind original / size_type 0 scale 100 width <val>
+ height <val>
+ scale <val>
+
+size_kind width_height / size_type 1 - scale <val>
+
+lyxsize_kind original / lyxsize_type 0 lyxscale 100 lyxscale <val>
+------------------------------------------------------------------------------
+[replace old-token by new-token, and remove any of subsequent tokens as listed]
+
+If "rotate" is absent, lyx2lyx should ignore "rotateAngle <val>":
+ if ( "rotateAngle <val>" is there WITHOUT being preceded by the keyword "rotate" )
+ then
+ replace "rotateAngle <val>" by "rotateAngle 0"
+
