          represented in LyX files.

          for wrapped figures.

2007-09-21 Pavel Sanda <ps@twin.jikos.cz>
        * Format incremented to 286: LyX now supports hyperref and some
          of its options.

2007-09-11 Bo Peng <ben.bob@gmail.com>
        * Format incremented to 285: Tweaks to embedded file format
          Remove inzip parameter from graphics insets.

2007-09-09 Helge Hafting <helge.hafting@aitel.hist.no>
        * Format incremented to 284: LyX now implements wrapped figures
          using wrapfig.sty instead of floatflt.sty. The latter
          is rather buggy, the former also has more options.
          No conversion as the .lyx doesn't change.
          The .tex export is slightly different, necessitating the
          format increase.

2007-09-08 Martin Vermeer <martin.vermeer@tkk.fi>

        * format incremented to 283: CharStyle insets are now
          called Flex.

2007-08-31 Bo Peng <ben.bob@gmail.com>

        * format incremented to 282: lyx files can be zipfiles with
          embedded documents.

2007-08-29 Richard Heck <rgheck@comcast.net>

        * format incremented to 281: allow modules for layout files

2007-08-17 Martin Vermeer <martin.vermeer@tkk.fi>

        * format incremented to 280: the show_label parameter
          is depreciated in favour of (Collapsable) status.

2007-08-17 Martin Vermeer <martin.vermeer@tkk.fi>

        * format incremented to 279: CharStyle names are now
          expected to be of form CharStyle:Name.

2007-08-12 José Matos <jamatos@fc.up.pt>

        * format incremented to 278: Close begin_deeper with a
          corresponding end_deeper (the only case where it matters is
          at the end of the body).

2007-08-12 José Matos <jamatos@fc.up.pt>

        * format incremented to 277: lyx is able to create invalid
          table where a multicolumn does not have a first cell
          (required by the table file format)

2007-07-20 Dov Feldstern <dov@lyx.org>

        * format *not* incremented; fixed format 249 conversion, so that it now
                correctly deals with encodings in footnotes (part of bug 3613)

2007-06-26 Uwe Stöhr <uwestoehr@web.de> and Dov Feldstern <dov@lyx.org>

        * format incremented to 276: switching exsting language 'arabic' to
                'arabic_arabtex'; this is to differentiate from the new arabic support
                using the arabi package.

2007-05-04  Jürgen Spitzmüller  <j.spitzmueller@gmx.de>

        * format incremented to 275: add graphics params scaleBeforeRotation
        (fix bug 1749).

2007-06-13 Dov Feldstern <dov@lyx.org>
        * format incremented to 274: applying the conversion done in format 259
                to the \lang property, which was forgotten back then... This is
                slightly more complicated, because the default language has to be
                determined on a per-paragraph basis.

2007-06-13 Bo Peng <ben.bob@gmail.com>
        * format incremented to 273: add --Separator-- environment to
                separate consecutive environments

2007-06-13 Bo Peng <bpeng@lyx.org>
        * format incremented to 272: convert listings to ERT because
                earlier versions of lyx can not handle unrecognizable
                listings parameters.

2007-05-15 José Matos <jamatos@lyx.org>
        * format incremented to 271: extended textclasses accept the
        normal font sizes: 10, 11 and 12pt.

2007-05-14 Martin Vermeer <martin.vermeer@tkk.fi>
        * format incremented to 270: support beamer \alert, \structure

2007-05-08 Bo Peng <ben.bob@gmail.com>
        * format incremented to 269: add listings support
        - add preamble flag \listings_params, e.g. \listings_params "language=Python,float"
        - add inset listings, with options lstparams and inline, e.g.
                \begin_inset listings
                lstparams "xleftmargin=50pt,language=Python"
                inline false
        - add \lstinputlisting Include type. e.g.
                \begin_inset Include \lstinputlisting{newfile1.lyx}[firstline=10,lastline=15]

2007-05-06 Uwe Stöhr  <uwestoehr@web.de>

        * format incremented to 268: add support for the CJK encodings
        - all encodings supported by CJK.sty are now in lib/encodings
        - lib/encoding has got two new flags:
          - encoding package:
            "inputenc" for those languages that use the inputenc-package and
            "CJK" for the CJK encodings
          - "fixed"/"variable" to divide between multi- or single-byte encoding
        - lib/languages allows now to set an empty language for babel
          in this case babel isn't called.

2007-05-04  Jürgen Spitzmüller  <j.spitzmueller@gmx.de>

        * format incremented to 267: add plain utf8 encoding (for XeTeX).

2007-04-29  Uwe Stöhr  <uwestoehr@web.de>

        * format incremented to 266:
        Support for the Armenian language

2007-04-26  Uwe Stöhr  <uwestoehr@web.de>

        * format incremented to 265: fix LyX's table border line handling
        With the fix (see bug 1746) LyX now takes care if the user has entered
        a "|" character in the argument field of tables. Therefore the "|"
        character has to be removed when also a table border is set.

2007-04-24  José Matos  <jamatos@lyx.org>

        * format incremented to 264:
        textclass cv is renamed simplecv

2007-02-22  José Matos  <jamatos@lyx.org>

        * format incremented to 263: changes in the language names (overdue):
          brazil -> brazilian
          portuges -> portuguese

2007-02-16  Georg Baum  <Georg.Baum@post.rwth-aachen.de>

        * format incremented to 262: Allow ascii \inputencoding

2007-02-14  Georg Baum  <Georg.Baum@post.rwth-aachen.de>

        * format incremented to 261: \output_changes is now considered
        even if \tracking_changes is false. This allows to output existing
        changes even if future changes are not tracked anymore.
        The old combination

        \tracking_changes false
        \output_changes true

        is therefore converted to

        \tracking_changes false
        \output_changes false

        on upgrade. Nothing is done on downgrade since the new behaviour is
        not supported in older formats.

2007-02-13  Georg Baum  <Georg.Baum@post.rwth-aachen.de>

        * format incremented to 260: Allow utf8x \inputencoding

2007-02-12  Georg Baum  <Georg.Baum@post.rwth-aachen.de>

        * format incremented to 259:
        Old: Spaces at start or end of font changes were output outside of
             the font change, i.e. not 'xx\textbf{ yy }zz', but
             'xx \textbf{yy} zz'.
        New: Spaces are always output with the font set by the user.

2007-01-31  Uwe Stöhr  <uwestoehr@web.de>

        * format incremented to 258: new \lyxline definition
        Old:
                \\newcommand{\\lyxline}[1]{
                  {#1 \\vspace{1ex} \\hrule width \\columnwidth \\vspace{1ex}}
                }
        New:
                \\newcommand{\\lyxline}[1][1pt]{%
                  \\par\\noindent%
                  \\rule[.5ex]{\\linewidth}{#1}\\par}
        The new definition is more robust, see bug 1988 and now really takes care about
        the fontsize: \lyxline{\Huge} produces now a thicker line than \lyxline{\normalfont}

2007-01-29  Georg Baum  <Georg.Baum@post.rwth-aachen.de>

        * 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).

2006-12-22  Georg Baum  <Georg.Baum@post.rwth-aachen.de>

        * format incremented to 256: allow some new inputenc settings.
        For the complete list, see lib/lyx2lyx/lyx_1_5.py.

2006-11-25  Georg Baum  <Georg.Baum@post.rwth-aachen.de>

        * format incremented to 255: new insets for \clearpage and
        \cleardoublepage. They are written inline to the file, exactly like
        \newpage.

2006-11-13  Georg Baum  <Georg.Baum@post.rwth-aachen.de>

        * format incremented to 254: new header parameter \use_esint.
        It can have the same values as \use_amsmath: 0 (off), 1 (auto) and
        2 (on).

2006-10-18  Georg Baum  <Georg.Baum@post.rwth-aachen.de>

        * format incremented to 253: new nomenclature and printnomenclature
        insets. These are standard InsetCommand with the following parameters:
        \nomenclature[prefix]{symbol}{description}
        \printnomenclature[labelwidth]

2006-10-15  Georg Baum  <Georg.Baum@post.rwth-aachen.de>

        * format incremented to 252: changed command inset syntax

        Old:

        \begin_inset LatexCommand \cmdname[opt1][opt2]{arg}
        preview true
        \end_inset

        and

        \bibitem [opt1]{arg}


        New:

        \begin_inset LatexCommand cmdname
        name1 "opt1"
        name2 "opt2"
        name3 "arg"
        preview true
        \end_inset

        The order of the parameters and for each parameter the name and
        optional/required bit is now stored in InsetCommandParams.

2006-10-03  Jürgen Spitzmüller  <j.spitzmueller@gmx.de>

        * format incremented to 251: save show_label param for charstyles.

        On revert, the show_label param is just removed. Nothing to convert.

2006-10-12  Martin Vermeer <martin.vermeer@hut.fi>

        * Format incremented to 250: allow optional arg to environments

        No material format change. Now optargs for environments are allowed
        to be specified in layout files and will be handled properly. When
        converted back to older formats, they will be ignored in LaTeX
        output.

2006-08-14  Georg Baum  <Georg.Baum@post.rwth-aachen.de>

        * format incremented to 249: Unicode

        LyX documents are now always encoded in utf8. The value of
        \inputencoding does now only determine the encoding of the created
        LaTeX file.
        Up to format 248 the value of \inputencoding did also determine the
        encoding of the LyX file:

        \inputencoding       LyX file encoding
        auto                 as determined by the document and character
                             languages
        default              ditto
        everything else      as determined by \inputencoding

        The difference between auto and default is only the LaTeX output:
        auto causes loading of the inputenc package, default does not.

2006-07-03  Georg Baum  <Georg.Baum@post.rwth-aachen.de>

        * format incremented to 248: Basic booktabs support

        The <features> tag has a new switch: booktabs="true|false".
        An absent switch is equivalent to booktabs="false".
        Horizontal lines are set with the booktabs package if this switch
        is on.

        The <row> tag of tabulars has the following new attributes:
        topspace, bottomspace and interlinespace. All take a LyXLength
        as value, or the special keyword "default".

2006-06-10  Jürgen Spitzmüller  <j.spitzmueller@gmx.de>

        * format incremented to 247. The Grand Font Interface Rewrite.
        (1) Split font selection to rm, sf, tt:
                \fontscheme -> \font_roman, \font_sans, \font_typewriter
                Change 246->247:
                        \fontscheme     \font_roman     \font_sans      \font_typewriter
                        default         default         default         default
                        ae              ae              default         default
                        times           times           default         default
                        palatino        palatino        default         default

                courier, lmodern, luximono, utopia.
        Support for the following font has been removed:
                pslatex (it's superseded by mathptmx (times)).

2006-06-03  Martin Vermeer  <martin.vermeer@hut.fi>

        * format incremented to 246. The framed.sty package is
        now supported with note types framed and shaded.

2005-10-12  Jürgen Spitzmüller  <j.spitzmueller@gmx.de>

        * format incremented to 245. The \quotes_times parameter
        has been removed.

2005-09-24  Jürgen Spitzmüller  <j.spitzmueller@gmx.de>

        * format incremented to 244. Rename '\InsetSpace \,'
        to '\InsetSpace \thinspace{}', because the comma was
        not parsed by lyxlex, and '\InsetSpace \space' to
        '\InsetSpace \space{}' in favour of consistency.

2005-07-18  José Matos  <jamatos@lyx.org>

        * format incremented to 243.

        * this change only affects the preamble, the paperpackage
          option was removed and papersize is changed to default.

2005-06-21  Jean-Marc Lasgouttes  <lasgouttes@lyx.org>

        * format incremented to 242. There is no file format per
        se, but the "frenchb" language has been removed from lib/language
        and has to be translated to "french" by lyx2lyx.

2005-02-03  Georg Baum  <Georg.Baum@post.rwth-aachen.de>

        * format incremented to 241.

        All following changes apply only to text in ERT insets. The
        rationale is that text in ERT is simply ASCII text, and nothing more.

        * paragraph breaks are now a single newline in latex and not a
        paragraph break anymore (bug 698).
        * \newline is not allowed anymore, because it is redundant (see above)
        * layouts other than Standard, paragraph parameters and font changes
        are not allowed anymore. They never made sense and were ignored for
        latex output, but now they can't be read or set anymore (bug 922).


2005-01-23  Jürgen Spitzmüller  <j.spitzmüller@gmx.de>

        * format incremented to 240.
        * new bufferparam:
                \output_changes {true|false}
        (should the change tracking marks be visible in the output or not?)
        * lyx2lyx should just delete the param in 239.

2005-01-06  José Matos  <jamatos@lyx.org>

        * format incremented to 239.
        * the paragraph parameters are displayed in their own line. This
        change is consistent with the insets behaviour, and corresponds
        to a more uniform treatment of the paragraphs since some of them
        had already their own line.

        An example of a single paragraph follows:

\begin_layout Standard
\paragraph_spacing single
\align left
Paragraph text.
\end_layout


2004-12-03  José Matos  <jamatos@lyx.org>

        * format incremented to 238.
        * The compatibility code to read old latex accents from 0.12.x in
        InsetLatexAccent::checkContents has been removed.
        The following translations are done:
                "\i \x"   -> "\i \x{}"
                "\i \xy"  -> "\i \x{y}"
                "\i \x y" -> "\i \x{y}"
                "\i \x\i" -> "\i \x{\i}"
                "\i \x\j" -> "\i \x{\j}"
        x is a latex accent command, y the base character. \, i and j are
        literal.
        lyx did these changes already from 0.12.x -> 215, but not lyx2lyx,
        so formats 215 - 237 can have both versions.


2004-10-10  José Matos  <jamatos@lyx.org>

        * format incremented to 237.
        * In the header, the following statments use now booleans values,
        instead of 0, 1:
                - \use_geometry
                - \use_bibtopic
                - \tracking_changes

2004-08-15  José Matos  <jamatos@lyx.org>

        * format incremented to 236.
        * Added tags:
                - \begin_document
                - \begin_header
                - \begin_body
                - \end_body

        * The options for \papersize are changed:
                Default -> default
                Custom -> custom
        * All whitespaces are removed at the end of lines, when
        not necessary. As an example we have all the lines in the header that
        do not belong to the preamble.

2004-07-01  Georg Baum  <Georg.Baum@post.rwth-aachen.de>

        * format incremented to 235.
        * \paperpackage had an off-by-one error. Translation table:

          234: a4    a4wide  widemarginsa4
          235: none  a4      a4wide         widemarginsa4

          The "widemarginsa4" setting of 235 has no equivalent in 234.

2004-05-12  Angus Leeming  <leeming@lyx.org>

        * format incremented to 234.
        * the citation engine is specified explicitly rather than being
        deduced from 3 bools.

        \use_natbib 1
        \use_numerical_citations 0   ->   \cite_engine <style>
        \use_jurabib 0

        where <style> is one of "basic", "natbib_authoryear",
        "natbib_numerical" or "jurabib".

2004-04-29  Georg Baum  <Georg.Baum@post.rwth-aachen.de>

        * format incremented to 233.
        * insetgraphics does not allow filenames without extension anymore.
        The complete filename has to be given.

2004-03-29  Jürgen Spitzmüller  <j.spitzmueller@gmx.de>

        * format incremented to 232.

        * Support for bibtopic (sectioned bibliographies).
          - bufferparam \use_bibtopic [1|0]
          - the bibtex inset has a second argument for bibtopic's
            btPrint{Cited|NotCited|All} command:
            < 231:
            \begin_inset LatexCommand \bibtex[<style>]{<database>}
            now:
            \begin_inset LatexCommand \bibtex[<style>][<btPrintX>]{<database>}
          Forwards, there's nothing to be done. Backwards, \usepackage[dot]{bibtopic}
          has to be inserted to the preamble. Instead of the bibtex inset, the LaTeX
          \bibliographystyle{<style>}
          \begin{btSect}{<database>}
          \<btprintX>
          \end{btSect}
          has to be inserted.

2004-03-29  Jürgen Spitzmüller  <j.spitzmueller@gmx.de>

        * format incremented to 231.

        * Support for sidewaysfigure/sidewaystable (rotating package).
        insetfloat has now a param \sideways [true|false] (default is false).
        The param should be erased on downwards conversion, if it was true,
        the inset should be replaced by
        \begin{sidewaysfigure} <content> \end{sidewaysfigure}
        resp.
        \begin{sidewaystable} <content> \end{sidewaystable}
        i.e. ERT.

2004-02-23  Jürgen Spitzmüller  <j.spitzmueller@gmx.de>

        * format incremented to 230.

        * Support for a second optional argument in insetcommand.
        currently, citation uses this to support natbibs second
        optional argument \cite[before][after]{key}.
        I think there's nothing to convert upwards. Downwards, the
        commands with 2 optional args need to be converted to ERT.

        * Support for jurabib (param \use_jurabib [1|0], default is 0).
        When converting downwards, \usepackage{jurabib} has to be added
        to the preamble and, if babel is used, \usepackage{babel} before
        (jurabib fails if babel is called afterwards). If the natbib commands
        are used together with jurabib, they have to be converted to ERT too.

2003-12-29  Jürgen Spitzmüller  <j.spitzmueller@gmx.de>

        * format incremented to 229.
        * Minipages cannot be read anymore. All minipage insets will
        be converted to frameless box insets between 228->229.

2003-12-15  Angus Leeming  <leeming@lyx.org>

        * format incremented to 228.
        * Change the output of all insets derived from InsetCollapsable
        except for InsetERT (which has a similar output already), changing lines
        "collapsed true" -> "status collapsed"
        "collapsed false" -> "status open".
        * Change the output of InsetERT, changing lines
        "status Collapsed" -> "status collapsed"
        "status Open" -> "status open".
        "status Inlined" -> "status inlined".

2003-12-10  Angus Leeming  <leeming@lyx.org>

        * format NOT incremented.
        * add a 'draft' option to InsetExternal.

2003-12-10  Angus Leeming  <leeming@lyx.org>

        * format incremented to 227.
        * Change the output of InsetBox:
        \begin_inset Boxed -> \begin_inset Box Boxed
        \begin_inset Doublebox -> \begin_inset Box Doublebox
        \begin_inset Frameless -> \begin_inset Box Frameless
        \begin_inset ovalbox -> \begin_inset Box ovalbox
        \begin_inset Ovalbox -> \begin_inset Box Ovalbox
        \begin_inset Shadowbox -> \begin_inset Box Shadowbox

2003-12-10  Angus Leeming  <leeming@lyx.org>

        * format incremented to 226.
        * Change the output of InsetNote:
        \begin_inset Note -> \begin_inset Note Note
        \begin_inset Comment -> \begin_inset Note Comment
        \begin_inset Greyedout -> \begin_inset Note Greyedout

2003-11-28  André Pönitz

        * Remove space_above/space_below from Paragraph.
    This is now handled by InsetVSpace.

2003-10-07  Angus Leeming  <leeming@lyx.org>

        * Add transformations to InsetExternal

        boundingBox 0 0 20 20           the dimensions of the B.B..

2003-10-07  Martin Vermeer  <martin.vermeer@hut.fi>

        * Added box inset. File format:

        \begin_inset Ovalbox            Boxed/Frameless/ovalbox/Ovalbox
                                            /Shadowbox/Doublebox
        position "b"                    t/c/b
        hor_pos "c"                     l/c/r/s

        collapsed false                 true/false

        \begin_layout Standard

        <box contents>
        \end_layout

        \end_inset

        This box (Frameless, has_inner_box=1, use_parbox=0) replaces
        the pre-existing Minipage inset. Parameters translate as follows:
        position                        0/1/2   -> t/c/b
        inner_position                  0/1/2/3 -> inner_pos c/t/b/s

        collapsed                       same

2003-08-19  Michael Schmitt  <michael.schmitt@teststep.org>

        * attribute valignment="center" is replaced by valignment="middle"
        for tabular columns and cells

2003-08-17  Martin Vermeer  <martin.vermeer@hut.fi>

        * Added branch inset. File format:

        branch definition in the header:
        \branch <branchname>
        \selected 0                    0/1
        \color #rrggbb
        \end_branch

        \begin_inset Branch <branchname>
        collapsed false                 true/false

        \begin_layout Standard

        <branch contents>
        \end_layout

        \end_inset

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 \,

2003-04-24  André Pönitz <poenitz@gmx.net>

        * Added eqref support:
        \begin_inset LatexCommand \eqref{label}

2003-03-14  Dekel Tsur

        * Format bumped to 223.

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"

Added \lyxlock for locked math inset when written to .lyx file.
When "downgrading" .lyx files this should simple be deleted but it
does not hurt at all if it stays in. It does not have to be added
when "upgrading".

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.

The 1.2.0 InsetGraphicsParams "size_type" and "lyxsize_type" have been
renamed as "size_kind" and "lyxsize_kind" respectively.

 \begin_inset Graphics FormatVersion 1
        filename file.eps
        display default
-       size_kind original
+       size_type original
        width 7cm
        rotateOrigin center
-       lyxsize_kind original
+       lyxsize_type original
        lyxwidth 4cm

 \end_inset
