1 !Important Changes in LyX 2.4.0
6 * It is now possible to cancel background export processes. A menu entry
7 to do so will appear on the Document menu when such a process is underway.
8 The LFUN for this is export-cancel. One can also click on the 'spinner'
11 * The items on the Edit menu have been reordered, and many of the shortcuts
12 have been changed so that they are more intuitive in the case of often
13 used items. We understand that this may frustrate some users and apologize,
14 while noting that menu shortcuts can always be customized by copying the
15 stdmenus.inc file to the user directory and editing it.
17 * Backspace will now merge paragraphs even when they have different layouts.
19 * Ctrl-click on a cross-reference will now take you to its label.
21 * Default shortcuts for saving bookmarks have been changed to Alt-NUM, where
22 NUM is the number of the bookmark. (They were previously Shift-F1, etc.)
24 * This allows Shift-F3 to be used for word-find-backwards (i.e., find previous)
27 * The shortcut for word-find on OSX is now Cmd-E, as is the Apple standard. The
28 shortcut for word-find-previous is Cmd-G.
30 * Continuous spellcheck is now on by default, but only if the user does not have
31 an existing preferences file. In that case, the old setting is preserved.
34 !!Documents compilation process and images conversion
36 * LyX now uses utf8 encoding per default for all languages. This does
37 not affect existing documents. Note that LyX also does not touch
38 personal defaults and templates. That is to say, if you still see
39 traditional encoding preset for new documents, you can change that
40 by selecting "Unicode (utf8) [default]" and hitting "Save as
41 Documents Defaults" afterwards. Your personal templates need to be
42 changed manually if desired.
44 * LyX defaults to the "HE8" LaTeX font encoding with Hebrew if the
45 "Culmus" LaTeX fonts are installed.
47 * Documents that use TeX fonts can only be compiled with XeTeX if the input
48 encoding is set to "utf8-plain" or "ascii".
50 * DocBook support has been revamped and now targets DocBook 5 (i.e.
51 only XML, SGML is gone). Some supporting files for the previous
52 implementation have been removed: all examples (lib/examples),
53 some layouts (existing documents should still work, but with a
54 DocBook 5 output instead of DocBook 4 SGML). The dependency on
55 sgmltools has been removed, this new support is always enabled.
56 Having sgmltools installed or not will not change anything in LyX.
58 !!!The following pref variables were added in 2.4:
60 * \ct_additions_underlined true|false: determines whether additions in change tracking
61 are underlined in the workarea (default: true).
63 * \ct_markup_copied true|false: determines whether change tracking markup should be
64 preserved on copy/paste (default: false).
66 * \citation_search_view lyxpaperview: determines whether external script "lyxpaperview"
67 should be used for looking up citation source.
70 !!!The following pref variables were changed in 2.4:
74 !!!The following pref variables are obsoleted in 2.4:
77 The font encoding is now automatically set depending on the document
81 This is no longer necessary due to the rewrite of the painter.
83 * \use_pixmap_cacheqimage
84 There is no evidence that this painting mode was useful anymore.
87 The function date-insert has been removed and superseded by info-insert date.
88 The latter does not need a pref value anymore.
91 !!!The following new LyX functions have been introduced in 2.4:
93 * bidi is a helper function to implement icons that are different between LTR and RTL text.
95 * buffer-reset-export advises LyX to remove the auxiliary files before doing the next
98 * buffer-write-as-template is a new convenience function to ease saving a document
99 in the (personal) templates folder.
101 * export-cancel: Used to cancel background export processes.
103 * font-nospellcheck marks the word under cursor or selection to the effect that the
104 spellchecker ignores it.
106 * ifrelatives is a helper function to check whether a buffer has a master or children.
108 * lyxfiles-open opens the new examples or templates dialog.
110 * master-buffer-forall executes an lfun in the master and all children of a document.
112 * paragraph-select is a new convenience function to select the paragraph
113 surrounding the actual cursor position.
115 * search-string-set [arg] stores the <arg>, the currently selected text or the word under
116 cursor in the search cache that is used by word-find[-backward|-forward] if no argument
119 * spelling-add-local adds words for a given language to the document's local spelling
122 * spelling-remove-local removes words for a given language from the document's local
125 * inset-split is a new convenience function that splits an inset into two at the given
126 cursor position. This is only implemented for text insets currently.
128 * tabular-style-insert: Insert a table in a specified style.
131 !!!The following LyX functions have been changed in 2.4:
133 * set-graphics-group was renamed to graphics-set-group.
135 * info-insert buffer vcs-*: renamed to info-insert vcs *
137 * file-insert: optional second parameter "ignorelang" to make the insertion
138 ignore the inserted file's main language (and rather adapt it to the insertion
142 !!!The following LyX functions have been removed in 2.4:
144 * date-insert: obsoleted by info-insert date.
146 !!!The following LyX function has been added and then removed in 2.4 development cycle.
148 * bidi: used as a first solution to provide icons that change
149 direction with language.
152 !!!The following LyX documents have been moved in 2.4:
154 * As a result of a major restructuring of the templates and example
155 directories, almost all examples and templates files have been renamed and
156 moved to subfolders that reflect the layout category.
157 The files now have much more decriptive (and longer) names, and they use
158 URL encoding for specific special characters such as '(', ')' and '&'.
159 Notably also the file that opens for new users has been renamed (from
160 splash.lyx to Welcome.lyx).
163 !!!The following new folders have been added to the LyX directory
165 * The examples and templates directories have been completely re-organized.
166 They are now much more structured (by means of layout categories) and thus
167 consist of many new subfolders.
171 !!!The following preferences files have been removed from the tarball in 2.4:
175 !!!The following metadata files have been added to the tarball in 2.4:
179 !!Changes with respect to external programs and libraries in 2.4:
181 * The Qt5 libraries are now used by default. In order to link against
182 Qt4 the configure option --disable-qt5 has to be used.
184 * The dependency on pplatex/dvipost was dropped.
186 * The dependency on sgmltools was dropped, see DocBook 5 section.
188 !!! Dependencies to generate ePub files:
190 * The DocBook XSLT 1.0 style sheets are a required dependency to generate
191 ePub files. All versions since 1.76.0 are supported.
193 Version 1.79.2 is bundled with LyX. If your system already provides xslt
194 style sheets you can use configure parameter --without-xslt-stylesheets to
195 avoid installing them.
198 * XSLT processor is needed, two options were successfully tested
200 - Works on Linux and OSX (tested with xsltproc 1.1.32).
203 - Tested on Linux, OSX and Windows.
204 - Java is a required dependency. Any JVM for Java 1.4 should be supported.
205 - Only Saxon versions 6.5.4 and 6.5.5 are supported.
206 - Version 6.5.5 is bundled with LyX. If your system already provides Saxon
207 (or xsltproc) you can use configure parameter --without-saxon to avoid
208 installation of this library.
211 !!Known issues in version 2.4.0
213 * See http://www.lyx.org/trac/wiki/BugTrackerHome
216 !!Caveats when upgrading from earlier versions to 2.4.x
218 * Autotools monolithic build option for building LyX binaries was removed,
219 for compilation speedup use parallel building on multiple cores instead.
221 * Several ttf fonts (esint10.ttf, stmary10.ttf, wasy10.ttf) were changed
222 to reflect the fact that newer Qt libraries do not support displaying certain
223 codepoints anymore (bug #8493, #10161).
224 Distribution packagers need to repack those font files in case they are
225 delivering the fonts as a separated package dependent from core LyX
226 in order to display correctly math symbols like \oint.
228 Also note, that while it is still possible to compile LyX against Qt 4
229 these math symbols will not be displayed correctly anymore on Qt 4.
231 !! If upgrading from a LyX version before 2.3.0
