* When using the document compare function, there is now an option to display the
differences using a special "Document Compare" author.
+* InsetRef now supports starred commands. The starred commands stop hyperref from
+ creating a link (and are only available when hyperref is used). There is a
+ checkbox "No Hyperlink" for this purpose.
+
+* Alt-Escape can be used to 'float' and redock widgets like the table of contents
+ or source view.
+
+* Edit > Paste operation now preserves newlines in text by default.
+
+* Dark mode on Windows is possible now by choosing "fusion" user interface style
+ in the user interface preferences dialog, your system style has to be set to dark.
+
+* One can now use the Text Properties dialog in mathed to not only change
+ colors but also other text properties, except strikethrough and language
+ settings.
+

!!Documents compilation process and images conversion
* LyX now uses utf8 encoding per default for all languages. This does
* Documents that use TeX fonts can only be compiled with XeTeX if the input
encoding is set to "utf8-plain" or "ascii".
+* With LyXHTML output, there are now different CSS classes generated for
+ different depths: enumi, enumii, enumiii, and enumiv, and similarly for
+ itemize: lyxitemi, etc. There is also a new HTMLClass tag, which makes it
+ easier to provide specific classes for paragraphs.
+
+* HTML support has been updated to output XHTML5 files. A major change is the
+ use of XML entities instead of HTML ones (e.g., LyX now outputs -
+ instead of ").
+
* DocBook support has been revamped and now targets DocBook 5 (i.e.
only XML, SGML is gone). Some supporting files for the previous
implementation have been removed: all examples (lib/examples),
sgmltools has been removed, this new support is always enabled.
Having sgmltools installed or not will not change anything in LyX.
+* Postscript -> PDF convertor (ps2pdf) uses -dALLOWPSTRANSPARENCY by
+ default now (implemented since ghostscript 9.53.3, see bug #12303).
+
+* There is a widespread ban on postscript conversions across different
+ linux distributions and there are currently two way how to address
+ various image conversion errors when typesetting your documents:
+ - either manually remove the bans of EPS/PDF coders in ImageMagick
+ policy.xml configuration file
+ - or install alternative converters for bitmap <-> postscript.
+ In particular pdftoppm (poppler-utils) and tiff2ps (libtiff-tools)
+ are now recognized and activated in case LyX detects ImageMagick
+ policy ban. These will allow eps<->png(jpg) conversion chain to
+ be found when processing your documents.
+ Package maintainers of distributions (e.g. openSUSE or Debian derivates)
+ where ghostscript conversions of ImageMagick are banned can simply
+ add dependencies for poppler-utils and libtiff-tools to workaround
+ the problem.
+
+* LyX now supports hebrew and hungarian quotation styles.
+
!!!The following pref variables were added in 2.4:
* \ct_additions_underlined true|false: determines whether additions in change tracking
!!!The following new LyX functions have been introduced in 2.4:
+* bibtex-database-list: output a list of all bibtex files used in the current buffer.
+ The function outputs absolute paths in the OS style and separated by the os-specific
+ path separator. This function is intended for bibliography managers.
+
+* branch-sync-all: Open/close all insets of selected branch (depending on its activation status).
+
* buffer-reset-export advises LyX to remove the auxiliary files before doing the next
export.
* index-tag-all adds a copy of the index entry under cursor to after all occurrences of the
word that precedes the index inset.
-
+
* inset-insert-copy inserts the inset's content (in ToC pane) at the position of the cursor.
* inset-split is a new convenience function that splits an inset into two at the given
!!!The following LyX functions have been changed in 2.4:
-* set-graphics-group was renamed to graphics-set-group.
-
-* info-insert buffer vcs-*: renamed to info-insert vcs *
+* citation-insert now returns a list of undefined citations if passed through the LyX Server.
* file-insert: optional second parameter "ignorelang" to make the insertion
ignore the inserted file's main language (and rather adapt it to the insertion
context's language).
+* info-insert buffer vcs-*: renamed to info-insert vcs *
+
+* inset-edit recognizes optional argument "nogui" - no editor will be launched in
+ such case, only filename will be returned (for use in scripts).
+
+* outline-in/out can now take argument "local", that restricts their
+ action to the current paragraph.
+
+* set-graphics-group was renamed to graphics-set-group.
+
* tabular-feature: added toggle parameters "toggle-all-lines", "toggle-border-lines"
and "toggle-inner-lines"
-* branch-sync-all: Open/close all insets of selected branch (depending on its activation status).
+* word-delete-forward, word-delete-backward, char-delete-forward,
+ char-delete-backward
+
+ The 2.4 behavior of these functions is almost equivalent to the
+ pre-2.3 behavior: without argument, it just deletes the
+ next/previous element; with the "confirm" argument however, big
+ insets are selected on the first call and deleted only on the
+ second. This new behavior allow scripts to work intuitively and
+ require the argument only for interactive use.
!!!The following LyX functions have been removed in 2.4:
splash.lyx to Welcome.lyx).
-!!!The following new folders have been added to the LyX directory
+!!!The following new files and folders have been added to the LyX directory
* The examples and templates directories have been completely re-organized.
They are now much more structured (by means of layout categories) and thus
consist of many new subfolders.
+* The file images/icon.aliases provides simple string substitution
+ rules that can be used when searching for an icon. This mechanism
+ can be used to handle icons for renamed lfuns or new arguments.
!!!The following preferences files have been removed from the tarball in 2.4:
!!Changes with respect to external programs and libraries in 2.4:
* The Qt5 libraries are now used by default. In order to link against
- Qt4 the configure option --disable-qt5 has to be used.
+ Qt6 the configure option --enable-qt6 has to be used. Qt4 is not
+ supported anymore.
* The dependency on pplatex/dvipost was dropped.
!!Known issues in version 2.4.0
-* See http://www.lyx.org/trac/wiki/BugTrackerHome
+* Various versions Qt6 have a problem with key events handling (QTBUG-123848).
+ This issue is documented in bug #12641 (e.g. LyX is unresponsive to
+ Control-Command keyboard shortcuts).
+ The fix for the Qt bug is announced for Qt 6.7, 6.5 and 6.2.
+
+* Gnome environments defaulting to Wayland + mutter compositor might be missing
+ proper window decorations. This is a generic problem which can be for Qt-based
+ applications (including LyX) alleviated by setting QT_QPA_PLATFORMTHEME=gnome
+ environment variable prior to running LyX.

!!Caveats when upgrading from earlier versions to 2.4.x
delivering the fonts as a separated package dependent from core LyX
in order to display correctly math symbols like \oint.
- Also note, that while it is still possible to compile LyX against Qt 4
- these math symbols will not be displayed correctly anymore on Qt 4.
+* Parentheses inside custom insets (defined in the local layout or in a
+ custom module) which has the "PassThru" tag set to true, in a hebrew text
+ will be reversed after conversion of existing documents.
+
+ To avoid that remove the "PassThru" tag, and restore it after
+ the conversion, or add the name of the inset, inset and the argument,
+ or layout and argument to the appropriate list, or dictionary in
+ the function "convert_hebrew_parentheses(document)" in lyx_2_4.py.
