!!Interface changes
-- It is now possible to cancel background export processes. A menu entry
+* 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.
-!!Documents compilation process and images conversion
+* 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 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.
+!!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".
+
+* 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 pref variables are obsoleted in 2.4:
+* \font_encoding
+ The font encoding is now automatically set depending on the document
+ fonts and languages.
+
* \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:
-LFUN_EXPORT_CANCEL: Used to cancel background export processes.
+* 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.
!!!The following LyX functions have been changed in 2.4:
-- LFUN_SET_GRAPHICS_GROUP was renamed into LFUN_GRAPHICS_SET_GROUP.
+* set-graphics-group was renamed to graphics-set-group.
+
+* info-insert buffer vcs-*: renamed to info-insert vcs *
+
+* 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).
+
+
+!!!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
+ 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
!!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.
