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
16 * LyX now outputs en- and em-dashes as -- and --- ligatures when exporting to
17 latex using TeX fonts, as done in version 2.1 and earlier. In version 2.2
18 they were instead output as the macros \textendash and \textemdash, causing
19 changed output with old documents and bugs. The 2.2 behavior can be restored
20 by don't allowing using dash ligatures in Document->Settings->Fonts.
22 * The following UI translations were dropped, because the lack of translation
23 maintenance: Russian, Danish, Greek, Serbian, Galician, Catalan, Romanian,
26 !!Documents compilation process and images conversion
28 * It is now possible to enable the -shell-escape option only for specific
29 documents, rather than having to enable it globally in preferences.
30 This is achieved by checking "Allow running external programs" in
31 Document->Settings->Formats. LyX will now check whether -shell-escape
32 has been added to a LaTeX converter and invites the user to remove it
33 in favor of the new mechanism when that LaTeX converter is used.
35 * The converters definition syntax (LYX_HOME/lyxrc*) now supports a
36 new option, 'needauth', to prevent completely automated execution of
37 the converter, unless LyX acquired explicit consent by the
38 user. This is a new security feature, useful for converters that are
39 capable of executing arbitrary code, such as R scripts (used with
40 sweave/knitr), embedded within LyX documents. The user needs to
41 explicitly grant per-document permission on the first need for using
42 the converter on each document, unless he/she checks the "Don't ask
43 again for this document" checkbox in the permission dialog. The new
44 behavior can be fine-tuned from two new options in the preferences
45 dialog (see their description below). These also allow for disabling
46 'needauth' converters altogether, if desired (default behavior).
48 * LyX now supports insertion and automated conversion of Gnuplot scripts,
49 recognized by their typical extension ".gp" or ".gnuplot". These can
50 directly be inserted in a LyX document using the "Insert->Graphics..."
51 dialog, then selecting the Gnuplot script. LyX automatically adds a
52 proper "set terminal ..." and "set output ..." line to convert the
53 file to the needed output format (e.g., .eps, .pdf), depending on
54 whether the document is being previewed on screen or compiled as PDF
55 or other formats. Terminal options cannot be fine-tuned at the moment,
56 but that's a capability that may come soon, also according to the
57 received feedback from users.
60 !!!The following pref variables were added in 2.3:
62 * \default_platex_view_format
63 Determine the default output format for Japanese documents that use the
64 pLaTeX backend [default: "pdf3" == "PDF (dvipdfm)"]
66 * \jbibtex_alternatives
67 Alternative bibliography converters for Japanese.
70 holds the name of the driver command used by the Pygments python module.
72 * \use_converter_needauth
73 when enabled, user is asked before calling any (possibly dangerous)
74 external converter with the 'needauth' option
76 * \use_converter_needauth_forbidden
77 when enabled, use of external converters with the 'needauth' option is
81 !!!The following pref variables were changed in 2.3:
84 New (default) value "auto".
87 This is now independent of the value set via buffer-zoom[-in|-out].
90 !!!The following new LyX functions have been introduced in 2.3:
92 * buffer-external-modification-clear
93 Clear the external modification flag on the current buffer
96 Zooms the screen fonts to a given value or resets to the default zoom
97 when no argument is given.
100 Toggles inversion status of branch inset.
103 Activate/deactivate the developer mode, which consists mainly in:
104 (1) more information shown in the status bar and (2) help file
105 opened in editable mode. This state used to be hardcoded at compile
109 Cross out characters.
111 * icon-size [size in px]
112 Set the icon size in the toolbar
115 Activates the LyX window. Useful in combination with reverse search.
118 Toggles movability of a given toolbar.
121 !!!The following LyX functions have been changed in 2.3:
124 If no or "default" argument is given, the function now exports to the default
127 * buffer-zoom-in, buffer-zoom-out
128 The Zoom value set by these is now relative to the default zoom value set in
132 This function now also applies to quote insets. It takes a three-character
133 string as an argument, referring (1.) to the style (e = ``english'',
134 s = ''swedish'', g = ,,german``, p = ,,polish'', f = <<french>>, a = >>danish<<),
135 (2.) to the side (l = left, r = right) and (3.) to the quotation level
136 (s = single, d = double). So "eld" means "English left double quotation mark".
137 A dot in the string means: take the current value. So "inset-modify changetype e.."
138 will only change the style to English, while letting side and level as is,
139 "inset-modify changetype f.s" will change the style to French and the level to
140 single, leaving the side value.
142 This function is most useful when combined with inset-forall. E.g.,
143 "inset-forall Quotes inset-modify changetype f.."
144 => change all quote insets to French style, maintaining current side and level
145 "inset-forall Quotes inset-modify changetype ..s"
146 => change all quote insets to single quotes, keeping style and level
147 "inset-forall Quotes inset-modify changetype g.s"
148 => change all quote insets to German single quotes, keeping left/right setting
151 The function has now two further optional arguments that determine end positions.
152 If specified, a selection is performed.
155 The function now has a second and third optional argument to specify
156 the side (left, right, auto) and quotation mark style (english, swedish,
157 german, polish, french, danish).
160 New option allowbreak that adds an invisible line break option,
162 * word-delete-forward, word-delete-backward, char-delete-forward,
164 The pre-2.3 behavior of these functions is equivalent to the 2.3 behavior with
165 the "force" option appended. The new default behavior (without "force") is
166 to select big insets on the first call and delete them only on the second.
167 This new behavior is consistent with how delete works in LyX's math editor.
170 !!!The following new folders have been added to the LyX directory
172 * citeengines: Contains the *.citeengine files that determine the citation
173 formatting and features.
175 * xtemplates: Contains the *.xtemplate files that define the external templates
176 (previously in the external_templates file).
179 !!!The following preferences files have been removed from the tarball in 2.3:
181 * external_templates. This files has been split into multiple *.xtemplate
182 files that are now shipped as content of the xtemplates directory.
185 !!Changes with respect to external programs and libraries in 2.3:
187 * Inkscape SVG with separate LaTeX + PDF output is experimentally supported.
189 * Add some editor/viewer applications to (re)configure checks.
192 !!Known issues in version 2.3.0
194 * See http://www.lyx.org/trac/wiki/BugTrackerHome.
197 !!Caveats when upgrading from earlier versions to 2.3.x
199 * The external_templates file has been split into one file per template,
200 which are now located in lib/xtemplates/*.xtemplate. This makes it easier
201 to add new templates or modify existing ones. If you have modified
202 the external_templates file, you will have to move the modifications to
203 the respective *.xtemplate file manually.
205 * If using TeX fonts and en- and em-dashes are output as font ligatures,
206 when exporting documents containing en- and em-dashes to the format of
207 LyX 2.0 or earlier, the following line has to be manually added to the
208 unicodesymbols file of that LyX version:<br>
209 0x200b "\\hspace{0pt}" "" "" "" "" # ZERO WIDTH SPACE<br>
210 This avoids "uncodable character" issues if the document is actually
211 loaded by that LyX version. LyX 2.1 and later versions already have the
212 necessary definition in their unicodesymbols file.
214 * If trying to compile documents using R scripts and sweave/knitr, LyX
215 2.3.x would not allow for re-running the R scripts, unless the user:
216 1) explicitly disables the "Forbid use of needauth converters"
217 option in the LyX preferences;
218 2) provides explicit consent to the use of the converter on the first
219 compilation of the R-enhanced document.
221 * LyX now gives a warning if a document mixes title and non-title layouts.
222 In some cases, this warning is harmless, but in other cases the document has
223 a serious problem even though the LaTeX command does not exit with error. For
224 example, create a document with a title layout, then a standard layout, and
225 then an author layout, and you will see in the PDF that the author is not
226 typeset as an author.
