+* 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.
+ The LFUN for this is export-cancel. One can also click on the 'spinner'
+ to cancel export.
+
+* 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.
+
+* Backspace 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.)
+
+* This allows Shift-F3 to be used for word-find-backwards (i.e., find previous)
+ on Linux and Windows.
+
+* The shortcut for word-find on OSX is now Cmd-E, as is the Apple standard. The
+ shortcut for word-find-previous is Cmd-G.
+
+* 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.
!!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.
- 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.
+* 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.
+ "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".
+
+* 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.
!!!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.
!!!The following pref variables were changed in 2.4:
!!!The following new LyX functions have been introduced in 2.4:
-* paragraph-select is a new convenience function to select the paragraph
- surrounding the actual cursor position.
+* bidi is a helper function to implement icons that are different between LTR and RTL text.
+
+* 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.
+
+* 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.
* 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:
* The Qt5 libraries are now used by default. In order to link against
Qt4 the configure option --disable-qt5 has to be used.
+* 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.
!!Known issues in version 2.4.0
* Autotools monolithic build option for building LyX binaries was removed,
for compilation speedup use parallel building on multiple cores instead.
-!! If upgrading from a LyX version before 2.3.0
-
-* Please additionally see the release notes from the versions in-between:
- https://wiki.lyx.org/LyX/ReleaseNotes
-
* 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.
+ 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.
