+* \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 following pref variables are obsoleted in 2.4:
+
+* \font_encoding
+ 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+ The function date-insert has been removed and superseded by info-insert date.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:
+
+* 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.
+
+* 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).
+
+* 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:
+
+* 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).
