1 !Important Changes in LyX 2.2.0
3 (: This file lists interface changes that might affect users in 2.2.0, some
4 known problems in LyX 2.2.0 and some things you have to take into account
5 when upgrading from earlier versions to a version of the 2.2.x series. :)
10 * The --Separator-- layout has been removed in favor of an environment
11 separator inset. There is no provision for inserting this inset from
12 the GUI (though some menu entries use it) as it is automatically inserted
13 when needed. See Section 3.4.6 of the User Guide for details.
15 * The prefix for subsections in labels and references has been changed from
16 "sub:" to "subsec:" in order to avoid a clash with subfloats (conflicting
17 \subref command, see #7550). Files are automatically converted to the new
18 scheme. Please assure that you adapt external refstyle or prettyref
19 definitions and your own layout files.
21 * Support for printing from within LyX (File> Print) has been removed. LyX's
22 printing support was very limited, and most users will want to print after
23 reviewing an output document (e.g., a PDF), anyway, which can be done from the
25 Users who would like to restore this functionality can create a
26 "printer" format from within LyX and then define, say, a
27 pdf->printer converter that does nothing but call lpd, or a2ps, or
28 whatever. The "printer" will then be available as an export option.
31 !!!The following pref variables were added in 2.2:
34 This variable was introduced to allow saving the document directory
35 path in the document. If allowed, LyX will be able to locate all
36 included files even when the document is manually moved/copied to
37 a different location. If a valid \origin tag is present and the
38 document was actually moved, the path of all included files is
39 updated relative to the new location and the new origin will be
40 recorded when saving again the document.
42 !!!The following pref variables were changed in 2.2:
46 !!!The following pref variables are obsoleted in 2.2:
49 This variable was introduced to guard against any bad consequence of
50 the then-new right-to-left languages support. It is no longer needed
51 because of improvements. Now right-to-left support is always enabled.
56 * \print_evenpage_flag
58 * \print_pagerange_flag
60 * \print_collcopies_flag
64 * \print_file_extension:
65 These were used for print support, which has been removed.
68 !!!The following new LyX functions have been introduced in 2.2:
71 Opens the last previewed output of the buffer, if it exists.
74 Moves the current tab one spot to the right.
76 * buffer-move-previous
77 Moves the current tab one spot to the left.
79 * tabular-feature is reintroduced to allow more flexibility for user
80 commands, whereas "inset-modify tabular" is now reserved for the tabular
81 dialog. In particular, "inset-modify tabular" is no longer caught by math grid
82 insets. The name tabular-feature is kept to avoid renaming icons. For more
83 information, see #9794.
85 !!!The following LyX functions have been changed in 2.2:
87 * word-upcase, word-lowcase and word-capitalize do not select the word
88 to operate on in the emacs way (that is, starting at cursor
89 position); this behaviour can be restored by using the argument
92 * Functionality of "inset-modify tabular" has changed. See description of the
93 new LyX function "tabular-feature" above.
95 !!!The following LyX key bindings have been changed in 2.2:
97 * For bindings where Control + {PgDn, PgUp} switches to the
98 {next, previous} tab, Control + Shift + {PgDn, PgUp} moves the current
99 tab to the {next, previous} tab.
101 * The shortcuts for "bookmark-save x" have been changed from C-M-S-x to S-Fx
102 ("x" stands for the number of the bookmark.)
104 !!!The following LyX documents have been moved in 2.2:
108 !!!The following metadata files have been added to the tarball in 2.2:
112 !!Changes with respect to external programs and libraries in 2.2:
114 * LyX 2.2.0 and the following 2.2.x releases will continue to work well with
115 Qt 4.5 (and later Qt 4.x) but will also support Qt 5.6, which brings some
116 advantages most notably for users with HiDPI displays. Note that if you
117 compile LyX with a Qt 5 release before 5.6 you are likely to run into
118 several regressions with respect to Qt 4.x. See #9215 for a list of bugs
119 related to compiling LyX with different versions of Qt.
121 * LyX now gives an error if the underlying LaTeX command exited with error.
124 !!Known issues in version 2.2.0
126 * LyX needs to be run under Python 2 and will not work properly on systems
127 where Python 3 is the default binary. See #7030 to know how to fix this
128 properly, since simple shebang conversion in *.py files will not be enough.
130 * If using LyX with Qt 4, it is possible to suddenly get keyboard keys wrong,
131 and deadlock. To work around the issue, you can disable IBus for LyX by
132 starting LyX as 'XMODIFIERS= lyx'. For further discussion and alternative
133 workarounds, see #9362.
136 !!Caveats when upgrading from earlier versions to 2.2.x
138 * BibTeX errors are now processed and cause LyX to show the errors dialog.
139 Before, these errors were ignored, which means that it may happen that
140 documents that compiled without error with a previous version now
141 compile with error. However, because now in 2.2.x users can click on
142 the "Show Output Anyway" button, the document can still be viewed.
144 * Missing characters in the output are now reported as errors. This leads
145 to error reports for documents that compiled without error before.
146 However, the error was always present but went undetected!
148 * Documents using Times fonts and containing Greek characters may now fail
149 to compile under pdflatex for users of MikTeX due to an automatically
150 half-installed "grtimes" package. A workaround in LyX was removed as it
151 stands in the way of alternative approaches (see #6469).
153 * With LuaTeX, LyX now uses polyglossia instead of babel if the language
154 package option "Automatic" is selected. In order to use babel, select
155 "Always babel" instead. This may be needed if a document uses code that
156 is specific to babel.
158 * As usual, when opening and saving a document that was created by a previous
159 major version of LyX (in this case 2.1.x), the file format is changed to
160 the new file format (in this case 2.2.x). What is different starting with
161 2.2.0 is that when we save a file that was not originally in the current LyX
162 format, we create a backup of the original file. We put it in the backup
163 directory, if one exists, otherwise in the directory the original file is
164 in. This is the same strategy as for normal backups. This backup file can be
165 helpful in case a bug in lyx2lyx caused data loss. For more information, see
