- The LFUN for this is export-cancel.
+* It is now possible to cancel background export processes at any time. A menu
+ entry to do so will appear on the Document menu when such a process is
+ underway. The LFUN for this is export-cancel. One can also click on the red
+ 'x' next to the spinner to cancel export. Thanks to this functionality, we now
+ remove the "Stop command?" prompt, which polled users whether to stop a long
+ process.
+* The items on the Edit menu have been reordered, and many of the shortcuts
+ have been changed so that they are more intuitive in the case of often
+ used items. We understand that this may frustrate some users and apologize,
+ while noting that menu shortcuts can always be customized by copying the
+ stdmenus.inc file to the user directory and editing it.
-!!Documents compilation process and images conversion
+* Backspace and other forms of deletion will now merge paragraphs even when they
+ have different layouts.
+
+* Ctrl-click on a cross-reference will now take you to its label.
+
+* Default shortcuts for saving bookmarks have been changed to Alt-NUM, where
+ NUM is the number of the bookmark. (They were previously Shift-F1, etc.)
+
+* Shift-F3 can be used for word-find-backwards (i.e., find previous) on Linux
+ and Windows.
+
+* The shortcut to use the selection for a find on macOS is now Cmd-E, as is the
+ Apple standard. The shortcut for find the next occurrence of the current
+ find buffer text is Cmd-G. The shortcut for toggle of font emphasis has been
+ changed to Cmd-Ctrl-E.
+
+* Continuous spellcheck is now on by default, but only if the user does not have
+ an existing preferences file. In that case, the old setting is preserved.
+
+* Document (or selection statistics) is now shown in status bar and can be
+ disabled by the context menu.
+
+* The actual enabled state of the synchronize TeX output option of the document
+ is used to enable or disable the menu item for forward-search.
+
+* 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.
+
+
+!!Documents compilation process and images conversion
+
+* LyX now uses utf8 encoding per default for all languages. This does
+ not affect existing documents. Note that LyX also does not touch
+ personal defaults and templates. That is to say, if you still see
+ traditional encoding preset for new documents, you can change that
+ by selecting "Unicode (utf8) [default]" and hitting "Save as
+ Documents Defaults" afterwards. Your personal templates need to be
+ changed manually if desired.
+
+* LyX defaults to the "HE8" LaTeX font encoding with Hebrew if the
+ "Culmus" LaTeX fonts are installed.
+
+* 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),
+ some layouts (existing documents should still work, but with a
+ DocBook 5 output instead of DocBook 4 SGML). The dependency on
+ 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
+ are underlined in the workarea (default: true).
+
+* \ct_markup_copied true|false: determines whether change tracking markup should be
+ preserved on copy/paste (default: false).
+* \citation_search_view lyxpaperview: determines whether external script "lyxpaperview"
+ should be used for looking up citation source.
+
+* \draw_strategy partial|backingstore: when this is set to
+ "backingstore", the drawing code will force the use of an
+ intermediate surface, instead of just drawing changed regions on
+ screen. Note that "backingstore" is actually always enforced on
+ macOS and Wayland (default: partial).
+
+* \screen_limit true|false: determines whether the text width on screen is limited
+ (both fullscreen and normal view).
+
+* \screen_width <length>: sets the width of the text on screen if \screen_limit is true.
!!!The following pref variables were changed in 2.4:
The font encoding is now automatically set depending on the document
fonts and languages.
+* \fullscreen_limit
+ Removed in favor of \screen_limit
+
+* \fullscreen_width
+ Removed in favor of \screen_width
+
* \use_qimage
This is no longer necessary due to the rewrite of the painter.
+* \use_pixmap_cacheqimage
+ There is no evidence that this painting mode was useful anymore.
+
+* \date_insert_format
+ The function date-insert has been removed and superseded by info-insert date.
+ The latter does not need a pref value anymore.
+
!!!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.
+
+* buffer-write-as-template is a new convenience function to ease saving a document
+ in the (personal) templates folder.
+
* export-cancel: Used to cancel background export processes.
+* font-nospellcheck marks the word under cursor or selection to the effect that the
+ spellchecker ignores it.
+
+* ifrelatives is a helper function to check whether a buffer has a master or children.
+
+* lyxfiles-open opens the new examples or templates dialog.
+
+* master-buffer-forall executes an lfun in the master and all children of a document.
+
+* paragraph-select is a new convenience function to select the paragraph
+ surrounding the actual cursor position.
+
+* search-string-set [arg] stores the <arg>, the currently selected text or the word under
+ cursor in the search cache that is used by word-find[-backward|-forward] if no argument
+ is given to those.
+
+* spelling-add-local adds words for a given language to the document's local spelling
+ dictionary.
+
+* spelling-remove-local removes words for a given language from the document's local
+ spelling dictionary.
+
+* 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
+ cursor position. This is only implemented for text insets currently.
+
+* tabular-style-insert: Insert a table in a specified style.
+
+* tab-group-next, tab-group-previous: Activate another tab group in split view.
+ The new functions bound to F6/S-F6 in CUA bindings.
+
!!!The following LyX functions have been changed in 2.4:
-* set-graphics-group was renamed to graphics-set-group.
+* 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"
+
+* 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:
+
+* date-insert: obsoleted by info-insert date.
+
+!!!The following LyX function has been added and then removed in 2.4 development cycle.
+
+* bidi: used as a first solution to provide icons that change
+ direction with language.
!!!The following LyX documents have been moved in 2.4:
+* As a result of a major restructuring of the templates and example
+ directories, almost all examples and templates files have been renamed and
+ moved to subfolders that reflect the layout category.
+ The files now have much more decriptive (and longer) names, and they use
+ URL encoding for specific special characters such as '(', ')' and '&'.
+ Notably also the file that opens for new users has been renamed (from
+ splash.lyx to Welcome.lyx).
!!!The following new 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 following preferences files have been removed from the tarball in 2.4:
!!!The following metadata files have been added to the tarball in 2.4:
+* Metainfo was updated from appdata.xml to org.lyx.LyX.metainfo.xml
+ and is by default installed to /usr/share/metainfo/ per freedesktop.org
+ recommendation.
!!Changes with respect to external programs and libraries in 2.4:
+* The Qt5 libraries are now used by default. In order to link against
+ Qt6 the configure option --enable-qt6 has to be used. Qt4 is not
+ supported anymore.
+
+* The dependency on pplatex/dvipost was dropped.
+
+* The dependency on sgmltools was dropped, see DocBook 5 section.
+
+!!! Dependencies to generate ePub files:
+
+* The DocBook XSLT 1.0 style sheets are a required dependency to generate
+ ePub files. All versions since 1.76.0 are supported.
+
+ Version 1.79.2 is bundled with LyX. If your system already provides xslt
+ style sheets you can use configure parameter --without-xslt-stylesheets to
+ avoid installing them.
+
+
+* XSLT processor is needed, two options were successfully tested
+ a) xsltproc
+ - Works on Linux and OSX (tested with xsltproc 1.1.32).
+ - Fails on Windows.
+ b) Saxon
+ - Tested on Linux, OSX and Windows.
+ - Java is a required dependency. Any JVM for Java 1.4 should be supported.
+ - Only Saxon versions 6.5.4 and 6.5.5 are supported.
+ - Version 6.5.5 is bundled with LyX. If your system already provides Saxon
+ (or xsltproc) you can use configure parameter --without-saxon to avoid
+ installation of this library.
+
+* bash_completion script was updated for a newer syntax.
!!Known issues in version 2.4.0
!!Caveats when upgrading from earlier versions to 2.4.x
+* LyX now uses the parskip package for vertical paragraph separation. Since the
+ output differs from the previous (sub-optimal) approach which applied paragraph
+ separation to sections, lists etc. as well, existing documents
+ are converted to use preamble code that maintains the previous layout.
+ The downside is that the workarea looks as if paragraph indendation rather
+ than paragraph separation was used (output is correct). We encourage you
+ to try if the new layout suits you, remove the respective preamble code
+ and re-set the paragraph separation to use the new layout.
+
+* Autotools monolithic build option for building LyX binaries was removed,
+ for compilation speedup use parallel building on multiple cores instead.
+
+* Several ttf fonts (esint10.ttf, stmary10.ttf, wasy10.ttf) were changed
+ to reflect the fact that newer Qt libraries do not support displaying certain
+ codepoints anymore (bug #8493, #10161).
+ Distribution packagers need to repack those font files in case they are
+ 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.
!! If upgrading from a LyX version before 2.3.0
