be safely dissolved, as it will be automatically inserted at export time
if needed, as usual.
+* The new setting
+ "Document->Settings->Fonts->Output em- and en-dash as ligatures" forces
+ output of en- and em-dashes as -- and --- when exporting to LaTeX.
+ It is is "true" by default but "false" when opening documents edited
+ with LyX 2.2.
+ See chapter 3.9.1.1 "Dashes and line breaks" of the User Guide and
+ "Caveats when upgrading from earlier versions to 2.3.x" below.
+
+* The following UI translations were dropped, because the lack of translation
+ maintenance: Russian, Danish, Greek, Serbian, Galician, Catalan, Romanian,
+ Dutch.
+
+!!Documents compilation process and images conversion
+
+* It is now possible to enable the -shell-escape option only for specific
+ documents, rather than having to enable it globally in preferences.
+ This is achieved by checking "Allow running external programs" in
+ Document->Settings->Formats. LyX will now check whether -shell-escape
+ has been added to a LaTeX converter and invites the user to remove it
+ in favor of the new mechanism when that LaTeX converter is used.
+
+* The converters definition syntax (LYX_HOME/lyxrc*) now supports a
+ new option, 'needauth', to prevent completely automated execution of
+ the converter, unless LyX acquired explicit consent by the
+ user. This is a new security feature, useful for converters that are
+ capable of executing arbitrary code, such as R scripts (used with
+ sweave/knitr), embedded within LyX documents. The user needs to
+ explicitly grant per-document permission on the first need for using
+ the converter on each document, unless he/she checks the "Don't ask
+ again for this document" checkbox in the permission dialog. The new
+ behavior can be fine-tuned from two new options in the preferences
+ dialog (see their description below). These also allow for disabling
+ 'needauth' converters altogether, if desired (default behavior).
+
+* LyX now supports insertion and automated conversion of Gnuplot scripts,
+ recognized by their typical extension ".gp" or ".gnuplot". These can
+ directly be inserted in a LyX document using the "Insert->Graphics..."
+ dialog, then selecting the Gnuplot script. LyX automatically adds a
+ proper "set terminal ..." and "set output ..." line to convert the
+ file to the needed output format (e.g., .eps, .pdf), depending on
+ whether the document is being previewed on screen or compiled as PDF
+ or other formats. Terminal options cannot be fine-tuned at the moment,
+ but that's a capability that may come soon, also according to the
+ received feedback from users.
+
!!!The following pref variables were added in 2.3:
+* \default_platex_view_format
+ Determine the default output format for Japanese documents that use the
+ pLaTeX backend [default: "pdf3" == "PDF (dvipdfm)"]
+
+* \jbibtex_alternatives
+ Alternative bibliography converters for Japanese.
+
+* \pygmentize_command
+ holds the name of the driver command used by the Pygments python module.
+
+* \use_converter_needauth
+ when enabled, user is asked before calling any (possibly dangerous)
+ external converter with the 'needauth' option
+
+* \use_converter_needauth_forbidden
+ when enabled, use of external converters with the 'needauth' option is
+ forbidden
-!!!The following pref variables were changed in 2.3:
-* \document_path
- Default is changed to ".". The best guess for where the user wants to save
- or find files is the directory the user started LyX from. Before, the
- default was always the home directory. If desired, the old behavior can be
- restored by changing the default path in Preferences > "Working directory".
+!!!The following pref variables were changed in 2.3:
+* \bibtex_command
+ New (default) value "auto".
-!!!The following pref variables are obsoleted in 2.3:
+* \screen_zoom
+ This is now independent of the value set via buffer-zoom[-in|-out].
!!!The following new LyX functions have been introduced in 2.3:
+* buffer-external-modification-clear
+ Clear the external modification flag on the current buffer
+
+* buffer-zoom
+ Zooms the screen fonts to a given value or resets to the default zoom
+ when no argument is given.
+
* branch-invert
Toggles inversion status of branch inset.
+* devel-mode-toggle
+ Activate/deactivate the developer mode, which consists mainly in:
+ (1) more information shown in the status bar and (2) help file
+ opened in editable mode. This state used to be hardcoded at compile
+ time.
+
+* font-crossout
+ Cross out characters.
+
+* icon-size [size in px]
+ Set the icon size in the toolbar
+
* lyx-activate
Activates the LyX window. Useful in combination with reverse search.
+* toolbar-movable
+ Toggles movability of a given toolbar.
+
!!!The following LyX functions have been changed in 2.3:
+* buffer-export
+ If no or "default" argument is given, the function now exports to the default
+ output format.
+
+* buffer-zoom-in, buffer-zoom-out
+ The Zoom value set by these is now relative to the default zoom value set in
+ preferences.
+
+* inset-modify
+ This function now also applies to quote insets. It takes a three-character
+ string as an argument, referring (1.) to the style (e = ``english'',
+ s = ''swedish'', g = ,,german``, p = ,,polish'', f = <<french>>, a = >>danish<<),
+ (2.) to the side (l = left, r = right) and (3.) to the quotation level
+ (s = single, d = double). So "eld" means "English left double quotation mark".
+ A dot in the string means: take the current value. So "inset-modify changetype e.."
+ will only change the style to English, while letting side and level as is,
+ "inset-modify changetype f.s" will change the style to French and the level to
+ single, leaving the side value.
+
+ This function is most useful when combined with inset-forall. E.g.,
+ "inset-forall Quotes inset-modify changetype f.."
+ => change all quote insets to French style, maintaining current side and level
+ "inset-forall Quotes inset-modify changetype ..s"
+ => change all quote insets to single quotes, keeping style and level
+ "inset-forall Quotes inset-modify changetype g.s"
+ => change all quote insets to German single quotes, keeping left/right setting
+
+* paragraph-goto
+ The function has now two further optional arguments that determine end positions.
+ If specified, a selection is performed.
+
* quote-insert
The function now has a second and third optional argument to specify
the side (left, right, auto) and quotation mark style (english, swedish,
german, polish, french, danish).
+* specialchar-insert
+ New option allowbreak that adds an invisible line break option,
+
+* word-delete-forward, word-delete-backward, char-delete-forward,
+ char-delete-backward
+ The pre-2.3 behavior of these functions is equivalent to the 2.3 behavior with
+ the "force" option appended. The new default behavior (without "force") is
+ to select big insets on the first call and delete them only on the second.
+ This new behavior is consistent with how delete works in LyX's math editor.
+
+
+!!!The following new folders have been added to the LyX directory
+
+* citeengines: Contains the *.citeengine files that determine the citation
+ formatting and features.
-!!!The following LyX documents have been moved in 2.3:
+* xtemplates: Contains the *.xtemplate files that define the external templates
+ (previously in the external_templates file).
-!!!The following metadata files have been added to the tarball in 2.3:
+!!!The following preferences files have been removed from the tarball in 2.3:
+
+* external_templates. This files has been split into multiple *.xtemplate
+ files that are now shipped as content of the xtemplates directory.
!!Changes with respect to external programs and libraries in 2.3:
-* Inkscape SVG with separate LaTeX + PDF output is experimentally supported.
+
+* Inkscape SVG with separate LaTeX + PDF or PS output is supported via External
+ Material.
+
+* Add some editor/viewer applications to (re)configure checks.
+
+* The included Hunspell has been upgraded to version 1.6.2.
+
+* The included libiconv has been upgraded to version 1.15.
!!Known issues in version 2.3.0
+* See http://www.lyx.org/trac/wiki/BugTrackerHome.
+
!!Caveats when upgrading from earlier versions to 2.3.x
+* The external_templates file has been split into one file per template,
+ which are now located in lib/xtemplates/*.xtemplate. This makes it easier
+ to add new templates or modify existing ones. If you have modified
+ the external_templates file, you will have to move the modifications to
+ the respective *.xtemplate file manually.
+
+* If you used literal em- and en-dashes in pre-2.2 documents,
+ you must manually unselect
+ "Document->Settings->Fonts->Output em- and en-dash as ligatures"
+ to ensure unchanged behaviour.
+
+* ZWSP characters (u200b) following literal em- and en-dashes are deleted by
+ lyx2lyx when converting to 2.3 format. If you used them as optional line
+ breaks after dashes, convert them to space insets before opening your
+ document with LyX 2.3 or the optional line breaks will be lost!
+
+* If using TeX fonts and en- and em-dashes are output as font ligatures,
+ when exporting documents containing en- and em-dashes to the format of
+ LyX 2.0 or earlier, the following line has to be manually added to the
+ unicodesymbols file of that LyX version:<br>
+ 0x200b "\\hspace{0pt}" "" "" "" "" # ZERO WIDTH SPACE<br>
+ This avoids "uncodable character" issues if the document is actually
+ loaded by that LyX version. LyX 2.1 and later versions already have the
+ necessary definition in their unicodesymbols file.
+
+* If trying to compile documents using R scripts and sweave/knitr, LyX
+ 2.3.x would not allow for re-running the R scripts, unless the user:
+ 1) explicitly disables the "Forbid use of needauth converters"
+ option in the LyX preferences;
+ 2) provides explicit consent to the use of the converter on the first
+ compilation of the R-enhanced document.
+
+* LyX now gives a warning if a document mixes title and non-title layouts.
+ In some cases, this warning is harmless, but in other cases the document has
+ a serious problem even though the LaTeX command does not exit with error. For
+ example, create a document with a title layout, then a standard layout, and
+ then an author layout, and you will see in the PDF that the author is not
+ typeset as an author.
