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 to use the selection for a find on macOS is now Cmd-E, as is the
28 Apple standard. The shortcut for find the next occurrence of the current
29 find buffer text is Cmd-G. The shortcut for toggle of font emphasis has been
30 changed to Cmd-Ctrl-E.
32 * Continuous spellcheck is now on by default, but only if the user does not have
33 an existing preferences file. In that case, the old setting is preserved.
36 !!Documents compilation process and images conversion
38 * LyX now uses utf8 encoding per default for all languages. This does
39 not affect existing documents. Note that LyX also does not touch
40 personal defaults and templates. That is to say, if you still see
41 traditional encoding preset for new documents, you can change that
42 by selecting "Unicode (utf8) [default]" and hitting "Save as
43 Documents Defaults" afterwards. Your personal templates need to be
44 changed manually if desired.
46 * LyX defaults to the "HE8" LaTeX font encoding with Hebrew if the
47 "Culmus" LaTeX fonts are installed.
49 * Documents that use TeX fonts can only be compiled with XeTeX if the input
50 encoding is set to "utf8-plain" or "ascii".
52 * DocBook support has been revamped and now targets DocBook 5 (i.e.
53 only XML, SGML is gone). Some supporting files for the previous
54 implementation have been removed: all examples (lib/examples),
55 some layouts (existing documents should still work, but with a
56 DocBook 5 output instead of DocBook 4 SGML). The dependency on
57 sgmltools has been removed, this new support is always enabled.
58 Having sgmltools installed or not will not change anything in LyX.
60 !!!The following pref variables were added in 2.4:
62 * \ct_additions_underlined true|false: determines whether additions in change tracking
63 are underlined in the workarea (default: true).
65 * \ct_markup_copied true|false: determines whether change tracking markup should be
66 preserved on copy/paste (default: false).
68 * \citation_search_view lyxpaperview: determines whether external script "lyxpaperview"
69 should be used for looking up citation source.
71 * \draw_strategy partial|backingstore: when this is set to
72 "backingstore", the drawing code will force the use of an
73 intermediate surface, instead of just drawing changed regions on
74 screen. Note that "backingstore" is actually always enforced on
75 macOS and Wayland (default: partial).
77 !!!The following pref variables were changed in 2.4:
81 !!!The following pref variables are obsoleted in 2.4:
84 The font encoding is now automatically set depending on the document
88 This is no longer necessary due to the rewrite of the painter.
90 * \use_pixmap_cacheqimage
91 There is no evidence that this painting mode was useful anymore.
94 The function date-insert has been removed and superseded by info-insert date.
95 The latter does not need a pref value anymore.
98 !!!The following new LyX functions have been introduced in 2.4:
100 * buffer-reset-export advises LyX to remove the auxiliary files before doing the next
103 * buffer-write-as-template is a new convenience function to ease saving a document
104 in the (personal) templates folder.
106 * export-cancel: Used to cancel background export processes.
108 * font-nospellcheck marks the word under cursor or selection to the effect that the
109 spellchecker ignores it.
111 * ifrelatives is a helper function to check whether a buffer has a master or children.
113 * lyxfiles-open opens the new examples or templates dialog.
115 * master-buffer-forall executes an lfun in the master and all children of a document.
117 * paragraph-select is a new convenience function to select the paragraph
118 surrounding the actual cursor position.
120 * search-string-set [arg] stores the <arg>, the currently selected text or the word under
121 cursor in the search cache that is used by word-find[-backward|-forward] if no argument
124 * spelling-add-local adds words for a given language to the document's local spelling
127 * spelling-remove-local removes words for a given language from the document's local
130 * inset-split is a new convenience function that splits an inset into two at the given
131 cursor position. This is only implemented for text insets currently.
133 * tabular-style-insert: Insert a table in a specified style.
136 !!!The following LyX functions have been changed in 2.4:
138 * set-graphics-group was renamed to graphics-set-group.
140 * info-insert buffer vcs-*: renamed to info-insert vcs *
142 * file-insert: optional second parameter "ignorelang" to make the insertion
143 ignore the inserted file's main language (and rather adapt it to the insertion
147 !!!The following LyX functions have been removed in 2.4:
149 * date-insert: obsoleted by info-insert date.
151 !!!The following LyX function has been added and then removed in 2.4 development cycle.
153 * bidi: used as a first solution to provide icons that change
154 direction with language.
157 !!!The following LyX documents have been moved in 2.4:
159 * As a result of a major restructuring of the templates and example
160 directories, almost all examples and templates files have been renamed and
161 moved to subfolders that reflect the layout category.
162 The files now have much more decriptive (and longer) names, and they use
163 URL encoding for specific special characters such as '(', ')' and '&'.
164 Notably also the file that opens for new users has been renamed (from
165 splash.lyx to Welcome.lyx).
168 !!!The following new folders have been added to the LyX directory
170 * The examples and templates directories have been completely re-organized.
171 They are now much more structured (by means of layout categories) and thus
172 consist of many new subfolders.
176 !!!The following preferences files have been removed from the tarball in 2.4:
180 !!!The following metadata files have been added to the tarball in 2.4:
182 * Metainfo was updated from appdata.xml to org.lyx.LyX.metainfo.xml
183 and is by default installed to /usr/share/metainfo/ per freedesktop.org
187 !!Changes with respect to external programs and libraries in 2.4:
189 * The Qt5 libraries are now used by default. In order to link against
190 Qt4 the configure option --disable-qt5 has to be used.
192 * The dependency on pplatex/dvipost was dropped.
194 * The dependency on sgmltools was dropped, see DocBook 5 section.
196 !!! Dependencies to generate ePub files:
198 * The DocBook XSLT 1.0 style sheets are a required dependency to generate
199 ePub files. All versions since 1.76.0 are supported.
201 Version 1.79.2 is bundled with LyX. If your system already provides xslt
202 style sheets you can use configure parameter --without-xslt-stylesheets to
203 avoid installing them.
206 * XSLT processor is needed, two options were successfully tested
208 - Works on Linux and OSX (tested with xsltproc 1.1.32).
211 - Tested on Linux, OSX and Windows.
212 - Java is a required dependency. Any JVM for Java 1.4 should be supported.
213 - Only Saxon versions 6.5.4 and 6.5.5 are supported.
214 - Version 6.5.5 is bundled with LyX. If your system already provides Saxon
215 (or xsltproc) you can use configure parameter --without-saxon to avoid
216 installation of this library.
219 !!Known issues in version 2.4.0
221 * See http://www.lyx.org/trac/wiki/BugTrackerHome
224 !!Caveats when upgrading from earlier versions to 2.4.x
226 * LyX now uses the parskip package for vertical paragraph separation. Since the
227 output differs from the previous (sub-optimal) approach which applied paragraph
228 separation to sections, lists etc. as well, existing documents
229 are converted to use preamble code that maintains the previous layout.
230 The downside is that the workarea looks as if paragraph indendation rather
231 than paragraph separation was used (output is correct). We encourage you
232 to try if the new layout suits you, remove the respective preamble code
233 and re-set the paragraph separation to use the new layout.
235 * Autotools monolithic build option for building LyX binaries was removed,
236 for compilation speedup use parallel building on multiple cores instead.
238 * Several ttf fonts (esint10.ttf, stmary10.ttf, wasy10.ttf) were changed
239 to reflect the fact that newer Qt libraries do not support displaying certain
240 codepoints anymore (bug #8493, #10161).
241 Distribution packagers need to repack those font files in case they are
242 delivering the fonts as a separated package dependent from core LyX
243 in order to display correctly math symbols like \oint.
245 Also note, that while it is still possible to compile LyX against Qt 4
246 these math symbols will not be displayed correctly anymore on Qt 4.
248 !! If upgrading from a LyX version before 2.3.0
