-!Important Changes in LyX 2.3.0
+!Important Changes in LyX 2.4.0
!!Interface changes
-* LyX now has "inverted" branch insets, which output their contents just in
- case a given branch is not "activated". This makes inclusion of alternate
- material in different versions easier.
+- 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.
-* When inserting a command or symbol in mathed, it is now automatically
- wrapped in a real inset (either \text or \ensuremath) assuring the correct
- mode, instead of being wrapped only in the output. The wrapping inset can
- be safely dissolved, as it will be automatically inserted at export time
- if needed, as usual.
-* LyX now outputs en- and em-dashes as -- and --- ligatures when exporting to
- latex using TeX fonts, as done in version 2.1 and earlier. In version 2.2
- they were instead output as the macros \textendash and \textemdash, causing
- changed output with old documents and bugs. The 2.2 behavior can be restored
- by don't allowing using dash ligatures in Document→Settings→Fonts.
+!!Documents compilation process and images conversion
-!!!The following pref variables were added in 2.3:
+!!!The following pref variables were added in 2.4:
-!!!The following pref variables were changed in 2.3:
-* \document_path
- Default is changed to ".". The best guess for where the user wants to save
- or find files is the directory the user started LyX from. Before, the
- default was always the home directory. If desired, the old behavior can be
- restored by changing the default path in Preferences > "Working directory".
+!!!The following pref variables were changed in 2.4:
-!!!The following pref variables are obsoleted in 2.3:
-!!!The following new LyX functions have been introduced in 2.3:
+!!!The following pref variables are obsoleted in 2.4:
-* branch-invert
- Toggles inversion status of branch inset.
+* \font_encoding
+ The font encoding is now automatically set depending on the document
+ fonts and languages.
-* lyx-activate
- Activates the LyX window. Useful in combination with reverse search.
+* \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.
-!!!The following LyX functions have been changed in 2.3:
+* \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.
-* quote-insert
- The function now has a second and third optional argument to specify
- the side (left, right, auto) and quotation mark style (english, swedish,
- german, polish, french, danish).
-* inset-modify
- This function now also applies to quote insets. It takes a three-character
- string as an argument, refering (1.) to the style (e = ``english'',
- s = ''swedish'', g = ,,german``, p = ,,polish'', f = <<french>>, a = >>danish<<),
- (2.) to the side (l = left, r = right) and (3.) to the quotation level
- (s = single, d = double). So "eld" means "English left double quotation mark".
- A dot in the string means: take the current value. So "inset-modify changetype e.."
- will only change the style to English, while letting side and level as is,
- "inset-modify changetype f.s" will change the style to French and the level to
- single, leaving the side value.
+!!!The following new LyX functions have been introduced in 2.4:
- This function is most useful when combined with inset-forall. E.g.,
- "inset-forall Quotes inset-modify changetype f.."
- => change all quote insets to French style, maintaining current side and level
- "inset-forall Quotes inset-modify changetype ..s"
- => change all quote insets to single quotes, keeping style and level
- "inset-forall Quotes inset-modify changetype g.s"
- => change all quote insets to German single quotes, keeping left/right setting
+* export-cancel: Used to cancel background export processes.
-!!!The following LyX documents have been moved in 2.3:
+!!!The following LyX functions have been changed in 2.4:
+* set-graphics-group was renamed to graphics-set-group.
-!!!The following metadata files have been added to the tarball in 2.3:
+* info-insert buffer vcs-*: renamed to info-insert vcs *
-!!Changes with respect to external programs and libraries in 2.3:
+!!!The following LyX functions have been removed in 2.4:
-* Inkscape SVG with separate LaTeX + PDF output is experimentally supported.
+* date-insert: obsoleted by info-insert date.
-* Add some editor/viewer applications to (re)configure checks.
-!!Known issues in version 2.3.0
+!!!The following LyX documents have been moved in 2.4:
-!!Caveats when upgrading from earlier versions to 2.3.x
-* If the "Use non-TeX fonts" and "Don't use ligatures for en- and em-dashes"
- document preferences are not checked, when exporting documents containing
- en- and em-dashes to the format of LyX 2.0 or earlier, the following line
- has to be manually added to the unicodesymbols file of that LyX version:<br>
- 0x200b "\\hspace{0pt}" "" "" "" "" # ZERO WIDTH SPACE<br>
- This avoids "uncodable character" issues if the document is actually
- loaded by that LyX version. LyX 2.1 and later versions already have the
- necessary definition in their unicodesymbols file.
+
+!!!The following new folders have been added to the LyX directory
+
+
+
+!!!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:
+
+
+
+!!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.
+
+
+
+!!Known issues in version 2.4.0
+
+* See http://www.lyx.org/trac/wiki/BugTrackerHome
+
+
+!!Caveats when upgrading from earlier versions to 2.4.x
+
+* 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.
