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.
23 !!Documents compilation process and images conversion
25 * The converters definition syntax (LYX_HOME/lyxrc*) now supports a
26 new option, 'needauth', to prevent completely automated execution of
27 the converter, unless LyX acquired explicit consent by the
28 user. This is a new security feature, useful for converters that are
29 capable of executing arbitrary code, such as R scripts (used with
30 sweave/knitr), embedded within LyX documents. The user needs to
31 explicitly grant per-document permission on the first need for using
32 the converter on each document, unless he/she checks the "Don't ask
33 again for this document" checkbox in the permission dialog. The new
34 behavior can be fine-tuned from two new options in the preferences
35 dialog (see their description below). These also allow for disabling
36 'needauth' converters altogether, if desired (default behavior).
39 !!!The following pref variables were added in 2.3:
41 * \use_converter_needauth
42 when enabled, user is asked before calling any external converter with the
45 * \use_converter_needauth_forbidden
46 when enabled, use of external converters with the 'needauth' option is
50 !!!The following pref variables were changed in 2.3:
53 Default is changed to ".". The best guess for where the user wants to save
54 or find files is the directory the user started LyX from. Before, the
55 default was always the home directory. If desired, the old behavior can be
56 restored by changing the default path in Preferences > "Working directory".
59 !!!The following pref variables are obsoleted in 2.3:
62 !!!The following new LyX functions have been introduced in 2.3:
65 Toggles inversion status of branch inset.
68 Activates the LyX window. Useful in combination with reverse search.
71 !!!The following LyX functions have been changed in 2.3:
74 The function now has a second and third optional argument to specify
75 the side (left, right, auto) and quotation mark style (english, swedish,
76 german, polish, french, danish).
79 This function now also applies to quote insets. It takes a three-character
80 string as an argument, refering (1.) to the style (e = ``english'',
81 s = ''swedish'', g = ,,german``, p = ,,polish'', f = <<french>>, a = >>danish<<),
82 (2.) to the side (l = left, r = right) and (3.) to the quotation level
83 (s = single, d = double). So "eld" means "English left double quotation mark".
84 A dot in the string means: take the current value. So "inset-modify changetype e.."
85 will only change the style to English, while letting side and level as is,
86 "inset-modify changetype f.s" will change the style to French and the level to
87 single, leaving the side value.
89 This function is most useful when combined with inset-forall. E.g.,
90 "inset-forall Quotes inset-modify changetype f.."
91 => change all quote insets to French style, maintaining current side and level
92 "inset-forall Quotes inset-modify changetype ..s"
93 => change all quote insets to single quotes, keeping style and level
94 "inset-forall Quotes inset-modify changetype g.s"
95 => change all quote insets to German single quotes, keeping left/right setting
97 * word-delete-forward, word-delete-backward, char-delete-forward,
99 The pre-2.3 behavior of these functions is equivalent to the 2.3 behavior with
100 the "force" option appended. The new default behavior (without "force") is
101 to select big insets on the first call and delete them only on the second.
102 This new behavior is consistent with how delete works in LyX's math editor.
104 !!!The following LyX documents have been moved in 2.3:
107 !!!The following new folders have been added to the LyX directory
109 * citeengines: Contains the *.citeengine files that determine the citation
110 formatting and features.
112 * xtemplates: Contains the *.xtemplate files that define the external templates
113 (previously in the external_templates file).
116 !!!The following preferences files have been removed from the tarball in 2.3:
118 * external_templates. This files has been split into multiple *.xtemplate
119 files that are now shipped as content of the xtemplates directory.
122 !!!The following metadata files have been added to the tarball in 2.3:
125 !!Changes with respect to external programs and libraries in 2.3:
127 * Inkscape SVG with separate LaTeX + PDF output is experimentally supported.
129 * Add some editor/viewer applications to (re)configure checks.
132 !!Known issues in version 2.3.0
135 !!Caveats when upgrading from earlier versions to 2.3.x
137 * The external_templates file has been split into one file per template,
138 which are now located in lib/xtemplates/*.xtemplate. This makes it easier
139 to add new templates or modify existing ones. If you have modified
140 the external_templates file, you will have to move the modifications to
141 the respective *.xtemplate file manually.
143 * If using TeX fonts and en- and em-dashes are output as font ligatures,
144 when exporting documents containing en- and em-dashes to the format of
145 LyX 2.0 or earlier, the following line has to be manually added to the
146 unicodesymbols file of that LyX version:<br>
147 0x200b "\\hspace{0pt}" "" "" "" "" # ZERO WIDTH SPACE<br>
148 This avoids "uncodable character" issues if the document is actually
149 loaded by that LyX version. LyX 2.1 and later versions already have the
150 necessary definition in their unicodesymbols file.
152 * If trying to compile documents using R scripts and sweave/knitr, LyX
153 2.3.x would not allow for re-running the R scripts, unless the user:
154 1) explicitly disables the "Forbid use of needauth converters"
155 option in the LyX preferences;
156 2) provides explicit consent to the use of the converter on the first
157 compilation of the R-enhanced document.
