1 !Important Changes in LyX 2.3.0
6 * LyX now has "inverted" branch insets, which output their contents just in
7 case a given branch is not "activated". This makes inclusion of alternate
8 material in different versions easier.
10 * When inserting a command or symbol in mathed, it is now automatically
11 wrapped in a real inset (either \text or \ensuremath) assuring the correct
12 mode, instead of being wrapped only in the output. The wrapping inset can
13 be safely dissolved, as it will be automatically inserted at export time
17 "Document->Settings->Fonts->Disallow line breaks after dashes"
18 turns off the conversion of em- and en-dash characters to --- and --
19 respectively for LaTeX export. It is is "false" by default.
20 See chapter 3.9.1.1 "Dashes and Line Breaks" of the User Guide and
21 "Caveats when upgrading from earlier versions to 2.3.x" below.
23 * The following UI translations were dropped, because the lack of translation
24 maintenance: Russian, Danish, Greek, Serbian, Galician, Catalan, Romanian,
27 !!Documents compilation process and images conversion
29 * It is now possible to enable the -shell-escape option only for specific
30 documents, rather than having to enable it globally in preferences.
31 This is achieved by checking "Allow running external programs" in
32 Document->Settings->Formats. LyX will now check whether -shell-escape
33 has been added to a LaTeX converter and invites the user to remove it
34 in favor of the new mechanism when that LaTeX converter is used.
36 * The converters definition syntax (LYX_HOME/lyxrc*) now supports a
37 new option, 'needauth', to prevent completely automated execution of
38 the converter, unless LyX acquired explicit consent by the
39 user. This is a new security feature, useful for converters that are
40 capable of executing arbitrary code, such as R scripts (used with
41 sweave/knitr), embedded within LyX documents. The user needs to
42 explicitly grant per-document permission on the first need for using
43 the converter on each document, unless he/she checks the "Don't ask
44 again for this document" checkbox in the permission dialog. The new
45 behavior can be fine-tuned from two new options in the preferences
46 dialog (see their description below). These also allow for disabling
47 'needauth' converters altogether, if desired (default behavior).
49 * LyX now supports insertion and automated conversion of Gnuplot scripts,
50 recognized by their typical extension ".gp" or ".gnuplot". These can
51 directly be inserted in a LyX document using the "Insert->Graphics..."
52 dialog, then selecting the Gnuplot script. LyX automatically adds a
53 proper "set terminal ..." and "set output ..." line to convert the
54 file to the needed output format (e.g., .eps, .pdf), depending on
55 whether the document is being previewed on screen or compiled as PDF
56 or other formats. Terminal options cannot be fine-tuned at the moment,
57 but that's a capability that may come soon, also according to the
58 received feedback from users.
61 !!!The following pref variables were added in 2.3:
63 * \default_platex_view_format
64 Determine the default output format for Japanese documents that use the
65 pLaTeX backend [default: "pdf3" == "PDF (dvipdfm)"]
67 * \jbibtex_alternatives
68 Alternative bibliography converters for Japanese.
71 holds the name of the driver command used by the Pygments python module.
73 * \use_converter_needauth
74 when enabled, user is asked before calling any (possibly dangerous)
75 external converter with the 'needauth' option
77 * \use_converter_needauth_forbidden
78 when enabled, use of external converters with the 'needauth' option is
82 !!!The following pref variables were changed in 2.3:
85 New (default) value "auto".
88 This is now independent of the value set via buffer-zoom[-in|-out].
91 !!!The following new LyX functions have been introduced in 2.3:
93 * buffer-external-modification-clear
94 Clear the external modification flag on the current buffer
97 Zooms the screen fonts to a given value or resets to the default zoom
98 when no argument is given.
101 Toggles inversion status of branch inset.
104 Activate/deactivate the developer mode, which consists mainly in:
105 (1) more information shown in the status bar and (2) help file
106 opened in editable mode. This state used to be hardcoded at compile
110 Cross out characters.
112 * icon-size [size in px]
113 Set the icon size in the toolbar
116 Activates the LyX window. Useful in combination with reverse search.
119 Toggles movability of a given toolbar.
122 !!!The following LyX functions have been changed in 2.3:
125 If no or "default" argument is given, the function now exports to the default
128 * buffer-zoom-in, buffer-zoom-out
129 The Zoom value set by these is now relative to the default zoom value set in
133 This function now also applies to quote insets. It takes a three-character
134 string as an argument, referring (1.) to the style (e = ``english'',
135 s = ''swedish'', g = ,,german``, p = ,,polish'', f = <<french>>, a = >>danish<<),
136 (2.) to the side (l = left, r = right) and (3.) to the quotation level
137 (s = single, d = double). So "eld" means "English left double quotation mark".
138 A dot in the string means: take the current value. So "inset-modify changetype e.."
139 will only change the style to English, while letting side and level as is,
140 "inset-modify changetype f.s" will change the style to French and the level to
141 single, leaving the side value.
143 This function is most useful when combined with inset-forall. E.g.,
144 "inset-forall Quotes inset-modify changetype f.."
145 => change all quote insets to French style, maintaining current side and level
146 "inset-forall Quotes inset-modify changetype ..s"
147 => change all quote insets to single quotes, keeping style and level
148 "inset-forall Quotes inset-modify changetype g.s"
149 => change all quote insets to German single quotes, keeping left/right setting
152 The function has now two further optional arguments that determine end positions.
153 If specified, a selection is performed.
156 The function now has a second and third optional argument to specify
157 the side (left, right, auto) and quotation mark style (english, swedish,
158 german, polish, french, danish).
161 New option allowbreak that adds an invisible line break option,
163 * word-delete-forward, word-delete-backward, char-delete-forward,
165 The pre-2.3 behavior of these functions is equivalent to the 2.3 behavior with
166 the "force" option appended. The new default behavior (without "force") is
167 to select big insets on the first call and delete them only on the second.
168 This new behavior is consistent with how delete works in LyX's math editor.
171 !!!The following new folders have been added to the LyX directory
173 * citeengines: Contains the *.citeengine files that determine the citation
174 formatting and features.
176 * xtemplates: Contains the *.xtemplate files that define the external templates
177 (previously in the external_templates file).
180 !!!The following preferences files have been removed from the tarball in 2.3:
182 * external_templates. This files has been split into multiple *.xtemplate
183 files that are now shipped as content of the xtemplates directory.
186 !!Changes with respect to external programs and libraries in 2.3:
188 * LyX now supports only macOS 10.9 and higher (due to using Qt 5.9).
190 * Inkscape SVG with separate LaTeX + PDF or PS output is supported via External
193 * Add some editor/viewer applications to (re)configure checks.
195 * The included Hunspell has been upgraded to version 1.6.2.
197 * The included libiconv has been upgraded to version 1.15.
199 * LyX now includes a Qt-based fallback-converter for Mac to compensate missing
200 ImageMagick convert utility.
203 !!Known issues in version 2.3.0
205 * See http://www.lyx.org/trac/wiki/BugTrackerHome.
208 !!Caveats when upgrading from earlier versions to 2.3.x
210 * The external_templates file has been split into one file per template,
211 which are now located in lib/xtemplates/*.xtemplate. This makes it easier
212 to add new templates or modify existing ones. If you have modified
213 the external_templates file, you will have to move the modifications to
214 the respective *.xtemplate file manually.
216 * By default, LyX 2.3 outputs en- and em-dashes as -- and --- respectively,
217 so that a line break can occur in the output immediately after the dash.
218 Sometimes, this results in undesired line breaks or overfull lines due to
219 suppression of hyphenation in the word preceding the dash.
220 Select "Document->Settings->Fonts->Disallow line breaks after dashes"
221 to keep the LyX 2.2 behaviour.
222 See chapter 3.9.1.1, "Dashes and Line Breaks", of the User Guide
225 * If trying to compile documents using R scripts and sweave/knitr, LyX
226 2.3.x would not allow for re-running the R scripts, unless the user:
227 1) explicitly disables the "Forbid use of needauth converters"
228 option in the LyX preferences;
229 2) provides explicit consent to the use of the converter on the first
230 compilation of the R-enhanced document.
232 * LyX now gives a warning if a document mixes title and non-title layouts.
233 In some cases, this warning is harmless, but in other cases the document has
234 a serious problem even though the LaTeX command does not exit with error. For
235 example, create a document with a title layout, then a standard layout, and
236 then an author layout, and you will see in the PDF that the author is not
237 typeset as an author.
