!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 2.3.0
|
||||
|
||||
|
||||
!!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.
|
||||
|
||||
* 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.
|
||||
|
||||
* 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 2.3:
|
||||
|
||||
|
||||
!!!The following pref variables were added in 2.2:
|
||||
|
||||
* \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.
|
||||
|
||||
!!!The following pref variables were changed in 2.2:
|
||||
!!!The following pref variables were changed in 2.3:
|
||||
|
||||
|
||||
|
||||
!!!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.
|
||||
|
||||
* \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.
|
||||
!!!The following pref variables are obsoleted in 2.3:
|
||||
|
||||
|
||||
!!!The following new LyX functions have been introduced in 2.2:
|
||||
|
||||
* buffer-view-cache
|
||||
Opens the last previewed output of the buffer, if it exists.
|
||||
|
||||
* buffer-move-next
|
||||
Moves the current tab one spot to the right.
|
||||
|
||||
* 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 changed in 2.2:
|
||||
|
||||
* 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:
|
||||
|
||||
* 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 LyX functions have been introduced in 2.3:
|
||||
|
||||
|
||||
|
||||
!!!The following metadata files have been added to the tarball in 2.2:
|
||||
!!!The following LyX functions have been changed in 2.3:
|
||||
|
||||
|
||||
|
||||
!!Changes with respect to external programs and libraries in 2.2:
|
||||
|
||||
* 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.
|
||||
|
||||
* The Qt libraries must have support for the SVG graphic format, because
|
||||
LyX now uses svg icons. If this support is lacking, icons cannot be shown.
|
||||
|
||||
* 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.
|
||||
!!!The following LyX documents have been moved in 2.3:
|
||||
|
||||
|
||||
!!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.
|
||||
|
||||
* LyX can produce LuaTeX output that is not compatible with the newest versions
|
||||
of the engine (e.g. 0.95.0, the version in TeX Live 2016). In a later 2.2.x
|
||||
version we plan to implement exporting of LuaTeX code that is compatible
|
||||
with the LuaTeX versions shipped with both TeX Live 2015 and TeX Live 2016.

|
||||
!!!The following metadata files have been added to the tarball in 2.3:
|
||||
|
||||
|
||||
!!Caveats when upgrading from earlier versions to 2.2.x
|
||||
!!Changes with respect to external programs and libraries in 2.3:
|
||||
|
||||
* 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.
|
||||
|
||||
* 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!
|
||||
!!Known issues in version 2.3.0
|
||||
|
||||
* 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).
|
||||
|
||||
* 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.
|
||||
!!Caveats when upgrading from earlier versions to 2.3.x
|
||||
|
||||
* 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.
