!Important Changes in LyX 2.4.0
|
|
|
|
|
|
!!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.
|
|
|
|
* 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
|
|
|
|
* 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".
|
|
|
|
!!!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).
|
|
|
|
|
|
!!!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The function date-insert has been removed and superseded by info-insert date.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:
|
|
|
|
* 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.
|
|
|
|
* ifrelatives is a helper function to check whether a buffer has a master or children.
|
|
|
|
* 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.
|
|
|
|
* tabular-style-insert: Insert a table in a specified style.
|
|
|
|
|
|
!!!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).
|
|
|
|
|
|
!!!The following LyX functions have been removed in 2.4:
|
|
|
|
* date-insert: obsoleted by info-insert date.
|
|
|
|
|
|
|
|
!!!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:
|
|
|
|
|
|
|
|
!!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.
