-!Important Changes in LyX 2.2.0
-
-(: This file lists interface changes that might affect users in 2.2.0, some
- known problems in LyX 2.2.0 and some things you have to take into account
- when upgrading from earlier versions to a version of the 2.2.x series. :)
+!Important Changes in LyX 2.4.0
!!Interface changes
-* The --Separator-- layout has been removed in favor of an environment
- separator inset. There is no provision for inserting this inset from
- the GUI (though some menu entries use it) as it is automatically inserted
- when needed. See Section 3.4.6 of the User Guide for details.
+- 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.
+
+
+!!Documents compilation process and images conversion
+
+
+
+!!!The following pref variables were added in 2.4:
+
+
-* The prefix for subsections in labels and references has been changed from
- "sub:" to "subsec:" in order to avoid a clash with subfloats (conflicting
- \subref command, see #7550). Files are automatically converted to the new
- scheme. Please assure that you adapt external refstyle or prettyref
- definitions and your own layout files.
+!!!The following pref variables were changed in 2.4:
-* Support for printing from within LyX (File> Print) has been removed. LyX's
- printing support was very limited, and most users will want to print after
- reviewing an output document (e.g., a PDF), anyway, which can be done from the
- PDF viewer.
- Users who would like to restore this functionality can create a
- "printer" format from within LyX and then define, say, a
- pdf->printer converter that does nothing but call lpd, or a2ps, or
- whatever. The "printer" will then be available as an export option.
-!!!The following pref variables were added in 2.2:
+!!!The following pref variables are obsoleted in 2.4:
-* \save_origin
- This variable was introduced to allow saving the document directory
- path in the document. If allowed, LyX will be able to locate all
- included files even when the document is manually moved/copied to
- a different location. If a valid \origin tag is present and the
- document was actually moved, the path of all included files is
- updated relative to the new location and the new origin will be
- recorded when saving again the document.
+* \font_encoding
+ The font encoding is now automatically set depending on the document
+ fonts and languages.
-!!!The following pref variables were changed in 2.2:
+* \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 pref variables are obsoleted in 2.2:
-* \rtl
- This variable was introduced to guard against any bad consequence of
- the then-new right-to-left languages support. It is no longer needed
- because of improvements. Now right-to-left support is always enabled.
+!!!The following new LyX functions have been introduced in 2.4:
-* \printer
-* \print_adapt_output
-* \print_command
-* \print_evenpage_flag
-* \print_oddpage_flag
-* \print_pagerange_flag
-* \print_copies_flag
-* \print_collcopies_flag
-* \print_reverse_flag
-* \print_to_printer
-* \print_to_file
-* \print_file_extension:
- These were used for print support, which has been removed.
+* export-cancel: Used to cancel background export processes.
-!!!The following new LyX functions have been introduced in 2.2:
+!!!The following LyX functions have been changed in 2.4:
-* buffer-view-cache
- Opens the last previewed output of the buffer, if it exists.
+* set-graphics-group was renamed to graphics-set-group.
-* buffer-move-next
- Moves the current tab one spot to the right.
+* info-insert buffer vcs-*: renamed to info-insert vcs *
-* buffer-move-previous
- Moves the current tab one spot to the left.
-* tabular-feature is reintroduced to allow more flexibility for user
- commands, whereas "inset-modify tabular" is now reserved for the tabular
- dialog. In particular, "inset-modify tabular" is no longer caught by math grid
- insets. The name tabular-feature is kept to avoid renaming icons. For more
- information, see #9794.
+!!!The following LyX functions have been removed in 2.4:
-!!!The following LyX functions have been changed in 2.2:
+* date-insert: obsoleted by info-insert date.
-* word-upcase, word-lowcase and word-capitalize do not select the word
- to operate on in the emacs way (that is, starting at cursor
- position); this behaviour can be restored by using the argument
- "partial".
-* Functionality of "inset-modify tabular" has changed. See description of the
- new LyX function "tabular-feature" above.
-!!!The following LyX key bindings have been changed in 2.2:
+!!!The following LyX documents have been moved in 2.4:
-* For bindings where Control + {PgDn, PgUp} switches to the
- {next, previous} tab, Control + Shift + {PgDn, PgUp} moves the current
- tab to the {next, previous} tab.
-* The shortcuts for "bookmark-save x" have been changed from C-M-S-x to S-Fx
- ("x" stands for the number of the bookmark.)
-!!!The following LyX documents have been moved in 2.2:
+!!!The following new folders have been added to the LyX directory
-!!!The following metadata files have been added to the tarball in 2.2:
+!!!The following preferences files have been removed from the tarball in 2.4:
-!!Changes with respect to external programs and libraries in 2.2:
+!!!The following metadata files have been added to the tarball in 2.4:
-* LyX 2.2.0 and the following 2.2.x releases will continue to work well with
- Qt 4.5 (and later Qt 4.x) but will also support Qt 5.6, which brings some
- advantages most notably for users with HiDPI displays. Note that if you
- compile LyX with a Qt 5 release before 5.6 you are likely to run into
- several regressions with respect to Qt 4.x. See #9215 for a list of bugs
- related to compiling LyX with different versions of Qt.
-* If compiling LyX on Windows with Qt 5.6, it is recommended to use MSVC 2015
- update 2 to avoid #9892.
-* LyX now gives an error if the underlying LaTeX command exited with error.
+!!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 2.2.0
-* LyX needs Python 2.7 at runtime. The python 2 interpreter needs to be named
- either 'python' or 'python2'.
- Building LyX usually works with Python 3 as well, but there might be cases
- where it does not work properly on systems where Python 3 is the default
- binary. See #7030 to know how to fix this properly, since simple shebang
- conversion in *.py files will not be enough.
-* If using LyX with Qt 4, it is possible to suddenly get keyboard keys wrong,
- and deadlock. To work around the issue, you can disable IBus for LyX by
- starting LyX as 'XMODIFIERS= lyx'. For further discussion and alternative
- workarounds, see #9362.
+!!Known issues in version 2.4.0
+* See http://www.lyx.org/trac/wiki/BugTrackerHome
-!!Caveats when upgrading from earlier versions to 2.2.x
-* BibTeX errors are now processed and cause LyX to show the errors dialog.
- Before, these errors were ignored, which means that it may happen that
- documents that compiled without error with a previous version now
- compile with error. However, because now in 2.2.x users can click on
- the "Show Output Anyway" button, the document can still be viewed.
+!!Caveats when upgrading from earlier versions to 2.4.x
-* Missing characters in the output are now reported as errors. This leads
- to error reports for documents that compiled without error before.
- However, the error was always present but went undetected!
+* Autotools monolithic build option for building LyX binaries was removed,
+ for compilation speedup use parallel building on multiple cores instead.
-* Documents using Times fonts and containing Greek characters may now fail
- to compile under pdflatex for users of MikTeX due to an automatically
- half-installed "grtimes" package. A workaround in LyX was removed as it
- stands in the way of alternative approaches (see #6469).
+!! If upgrading from a LyX version before 2.3.0
-* With LuaTeX, LyX now uses polyglossia instead of babel if the language
- package option "Automatic" is selected. In order to use babel, select
- "Always babel" instead. This may be needed if a document uses code that
- is specific to babel.
+* Please additionally see the release notes from the versions in-between:
+ https://wiki.lyx.org/LyX/ReleaseNotes
-* As usual, when opening and saving a document that was created by a previous
- major version of LyX (in this case 2.1.x), the file format is changed to
- the new file format (in this case 2.2.x). What is different starting with
- 2.2.0 is that when we save a file that was not originally in the current LyX
- format, we create a backup of the original file. We put it in the backup
- directory, if one exists, otherwise in the directory the original file is
- in. This is the same strategy as for normal backups. This backup file can be
- helpful in case a bug in lyx2lyx caused data loss. For more information, see
- #9554.
+* 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.
