!!Interface changes
-* It is now possible to cancel background export processes. 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 'spinner'
- to cancel export.
+* 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
while noting that menu shortcuts can always be customized by copying the
stdmenus.inc file to the user directory and editing it.
-* Backspace will now merge paragraphs even when they have different layouts.
+* 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.
+
+* 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
* Documents that use TeX fonts can only be compiled with XeTeX if the input
encoding is set to "utf8-plain" or "ascii".
-
-* 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
+
+* 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
* \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.
!!!The following new LyX functions have been introduced in 2.4:
-* bidi is a helper function to implement icons that are different between LTR and RTL text.
+* 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.
* 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.
* 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.
+ 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.
+!!!The following LyX functions have been changed in 2.4:
-* 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"
+
+* 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.
+ 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:
!!!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
- 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.
* The dependency on sgmltools was dropped, see DocBook 5 section.
-* Java is a required dependency to generate ePub files. Any JVM for Java 1.4
- should be supported.
-
-* Saxon is a required dependency to generate ePub files. Only versions 6.5.4
- and 6.5.5 are supported. Version 6.5.5 is bundled with LyX.
+!!! 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.
+ 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
-* 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.
+
+* For others see http://www.lyx.org/trac/wiki/BugTrackerHome
!!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).
+ 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.
+* 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.
