!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. :)
!!Interface changes
* The --Separator-- layout has been removed in favor of an environment
separator inset. There is no provision for inserting this inset from
2015-05-21 21:32:44 +00:00
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
2015-12-11 10:53:37 +00:00
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 2.2:
* \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 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 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.
!!!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".
!!!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 metadata files have been added to the tarball in 2.2:
!!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.
* LyX now gives an error if the underlying LaTeX command exited with error.
!!Known issues in version 2.2.0
* LyX needs to be run under Python 2 and will 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.
!!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.
* 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!
* 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.
