There is no provision for inserting this inset from - the GUI (though some menu entries use it) as it is automatically inserted - when needed. See Section 3.4.6 of the User Guide for details. +* It is now possible to cancel background export processes. A menu entry + to do so will appear on the Document menu when such a process is underway. + The LFUN for this is export-cancel. One can also click on the 'spinner' + to cancel export. + +* The items on the Edit menu have been reordered, and many of the shortcuts + have been changed so that they are more intuitive in the case of often + used items. We understand that this may frustrate some users and apologize, + while noting that menu shortcuts can always be customized by copying the + stdmenus.inc file to the user directory and editing it. + +* Backspace will now merge paragraphs even when they have different layouts. + +* Ctrl-click on a cross-reference will now take you to its label. + +* Default shortcuts for saving bookmarks have been changed to Alt-NUM, where + NUM is the number of the bookmark. (They were previously Shift-F1, etc.) + +* This allows Shift-F3 to be used for word-find-backwards (i.e., find previous) + on Linux and Windows. + +* The shortcut to use the selection for a find on macOS is now Cmd-E, as is the + Apple standard. The shortcut for find the next occurrence of the current + find buffer text is Cmd-G. The shortcut for toggle of font emphasis has been + changed to Cmd-Ctrl-E. + +* Continuous spellcheck is now on by default, but only if the user does not have + an existing preferences file. In that case, the old setting is preserved. + +* Document (or selection statistics) is now shown in status bar and can be + disabled by the context menu. + +* The actual enabled state of the synchronize TeX output option of the document + is used to enable or disable the menu item for forward-search. + +!!Documents compilation process and images conversion + +* LyX now uses utf8 encoding per default for all languages. This does + not affect existing documents. Note that LyX also does not touch + personal defaults and templates. That is to say, if you still see + traditional encoding preset for new documents, you can change that + by selecting "Unicode (utf8) [default]" and hitting "Save as + Documents Defaults" afterwards. Your personal templates need to be + changed manually if desired. + +* LyX defaults to the "HE8" LaTeX font encoding with Hebrew if the + "Culmus" LaTeX fonts are installed. + +* Documents that use TeX fonts can only be compiled with XeTeX if the input + encoding is set to "utf8-plain" or "ascii". + +* DocBook support has been revamped and now targets DocBook 5 (i.e. + only XML, SGML is gone). Some supporting files for the previous + implementation have been removed: all examples (lib/examples), + some layouts (existing documents should still work, but with a + DocBook 5 output instead of DocBook 4 SGML). The dependency on + sgmltools has been removed, this new support is always enabled. + Having sgmltools installed or not will not change anything in LyX. + +!!!The following pref variables were added in 2.4: + +* \ct_additions_underlined true|false: determines whether additions in change tracking + are underlined in the workarea (default: true). + +* \ct_markup_copied true|false: determines whether change tracking markup should be + preserved on copy/paste (default: false). + +* \citation_search_view lyxpaperview: determines whether external script "lyxpaperview" + should be used for looking up citation source. + +* \draw_strategy partial|backingstore: when this is set to + "backingstore", the drawing code will force the use of an + intermediate surface, instead of just drawing changed regions on + screen. Note that "backingstore" is actually always enforced on + macOS and Wayland (default: partial). + +* \screen_limit true|false: determines whether the text width on screen is limited + (both fullscreen and normal view). + +* \screen_width : sets the width of the text on screen if \screen_limit is true. + +!!!The following pref variables were changed in 2.4: + + + +!!!The following pref variables are obsoleted in 2.4: + +* \font_encoding + The font encoding is now automatically set depending on the document + fonts and languages. + +* \fullscreen_limit + Removed in favor of \screen_limit + +* \fullscreen_width + Removed in favor of \screen_width + +* \use_qimage + This is no longer necessary due to the rewrite of the painter. + +* \use_pixmap_cacheqimage + There is no evidence that this painting mode was useful anymore. + +* \date_insert_format + The function date-insert has been removed and superseded by info-insert date. + The latter does not need a pref value anymore. + + +!!!The following new LyX functions have been introduced in 2.4: + +* buffer-reset-export advises LyX to remove the auxiliary files before doing the next + export. + +* buffer-write-as-template is a new convenience function to ease saving a document + in the (personal) templates folder. + +* export-cancel: Used to cancel background export processes. + +* font-nospellcheck marks the word under cursor or selection to the effect that the + spellchecker ignores it. + +* ifrelatives is a helper function to check whether a buffer has a master or children. + +* lyxfiles-open opens the new examples or templates dialog. + +* master-buffer-forall executes an lfun in the master and all children of a document. + +* paragraph-select is a new convenience function to select the paragraph + surrounding the actual cursor position. + +* search-string-set [arg] stores the , the currently selected text or the word under + cursor in the search cache that is used by word-find[-backward|-forward] if no argument + is given to those. + +* spelling-add-local adds words for a given language to the document's local spelling + dictionary. + +* spelling-remove-local removes words for a given language from the document's local + spelling dictionary. + +* index-tag-all adds a copy of the index entry under cursor to after all occurrences of the + word that precedes the index inset. + +* inset-insert-copy inserts the inset's content (in ToC pane) at the position of the cursor. + +* inset-split is a new convenience function that splits an inset into two at the given + cursor position. This is only implemented for text insets currently. + +* tabular-style-insert: Insert a table in a specified style. + + +!!!The following LyX functions have been changed in 2.4: + +* set-graphics-group was renamed to graphics-set-group. + +* info-insert buffer vcs-*: renamed to info-insert vcs * + +* file-insert: optional second parameter "ignorelang" to make the insertion + ignore the inserted file's main language (and rather adapt it to the insertion + context's language). + +* tabular-feature: added toggle parameters "toggle-all-lines", "toggle-border-lines" + and "toggle-inner-lines" -* The prefix for subsections in labels and references has been changed from - "sub:" to "subsec:" in order to avoid a clash with subfloats (conflicting - \subref command, see bug #7550). Files are automatically converted to the new - scheme. Please assure that you adapt external refstyle or prettyref - definitions and your own layout files. +* branch-sync-all: Open/close all insets of selected branch (depending on its activation status). -* Support for printing from within LyX (File> Print) has been removed. LyX's - printing support was very limited, and most users will want to print after - reviewing an output document (e.g., a PDF), anyway, which can be done from the - PDF viewer. - Users who would like to restore this functionality can create a - "printer" format from within LyX and then define, say, a - pdf->printer converter that does nothing but call lpd, or a2ps, or - whatever. The "printer" will then be available as an export option. +!!!The following LyX functions have been removed in 2.4: -!!!The following pref variables were added in 2.2: +* date-insert: obsoleted by info-insert date. -* \save_origin - This variable was introduced to allow saving the document directory - path in the document. If allowed, LyX will be able to locate all - included files even when the document is manually moved/copied to - a different location. If a valid \origin tag is present and the - document was actually moved, the path of all included files is - updated relative to the new location and the new origin will be - recorded when saving again the document. +!!!The following LyX function has been added and then removed in 2.4 development cycle. -!!!The following pref variables were changed in 2.2: +* bidi: used as a first solution to provide icons that change + direction with language. +!!!The following LyX documents have been moved in 2.4: -!!!The following pref variables are obsoleted in 2.2: +* As a result of a major restructuring of the templates and example + directories, almost all examples and templates files have been renamed and + moved to subfolders that reflect the layout category. + The files now have much more decriptive (and longer) names, and they use + URL encoding for specific special characters such as '(', ')' and '&'. + Notably also the file that opens for new users has been renamed (from + splash.lyx to Welcome.lyx). -* \rtl - This variable was introduced to guard against any bad consequence of - the then-new right-to-left languages support. It is no longer needed - because of improvements. Now right-to-left support is always enabled. -* \printer -* \print_adapt_output -* \print_command -* \print_evenpage_flag -* \print_oddpage_flag -* \print_pagerange_flag -* \print_copies_flag -* \print_collcopies_flag -* \print_reverse_flag -* \print_to_printer -* \print_to_file -* \print_file_extension: - These were used for print support, which has been removed. +!!!The following new folders have been added to the LyX directory +* The examples and templates directories have been completely re-organized. + They are now much more structured (by means of layout categories) and thus + consist of many new subfolders. -!!!The following new LyX functions have been introduced in 2.2: -* buffer-view-cache - Opens the last previewed output of the buffer, if it exists. -* buffer-move-next - Moves the current tab one spot to the right. +!!!The following preferences files have been removed from the tarball in 2.4: -* buffer-move-previous - Moves the current tab one spot to the left. -!!!The following LyX functions have been changed in 2.2: +!!!The following metadata files have been added to the tarball in 2.4: -* word-upcase, word-lowcase and word-capitalize do not select the word - to operate on in the emacs way (that is, starting at cursor - position); this behaviour can be restored by using the argument - "partial". +* Metainfo was updated from appdata.xml to org.lyx.LyX.metainfo.xml + and is by default installed to /usr/share/metainfo/ per freedesktop.org + recommendation. -!!!The following LyX key bindings have been changed in 2.2: -* For bindings where Control + {PgDn, PgUp} switches to the - {next, previous} tab, Control + Shift + {PgDn, PgUp} moves the current - tab to the {next, previous} tab. +!!Changes with respect to external programs and libraries in 2.4: -* The shortcuts for "bookmark-save x" have been changed from C-M-S-x to S-Fx - ("x" stands for the number of the bookmark.) +* The Qt5 libraries are now used by default. In order to link against + Qt4 the configure option --disable-qt5 has to be used. +* The dependency on pplatex/dvipost was dropped. -!!!The following LyX documents have been moved in 2.2: +* The dependency on sgmltools was dropped, see DocBook 5 section. +!!! Dependencies to generate ePub files: +* The DocBook XSLT 1.0 style sheets are a required dependency to generate + ePub files. All versions since 1.76.0 are supported. -!!!The following metadata files have been added to the tarball in 2.2: + Version 1.79.2 is bundled with LyX. If your system already provides xslt + style sheets you can use configure parameter --without-xslt-stylesheets to + avoid installing them. +* XSLT processor is needed, two options were successfully tested + a) xsltproc + - Works on Linux and OSX (tested with xsltproc 1.1.32). + - Fails on Windows. + b) Saxon + - Tested on Linux, OSX and Windows. + - Java is a required dependency. Any JVM for Java 1.4 should be supported. + - Only Saxon versions 6.5.4 and 6.5.5 are supported. + - Version 6.5.5 is bundled with LyX. If your system already provides Saxon + (or xsltproc) you can use configure parameter --without-saxon to avoid + installation of this library. -!!Changes with respect to external programs and libraries in 2.2: +* bash_completion script was updated for a newer syntax. -* LyX 2.2.0 and the following 2.2.x releases will continue to work well with - Qt 4.5 (and later Qt 4.x) but will also support Qt 5.6, which brings some - advantages most notably for users with HiDPI displays. Note that if you - compile LyX with a Qt 5 release before 5.6 you are likely to run into - several regressions with respect to Qt 4.x. See #9215 for a list of bugs - related to compiling LyX with different versions of Qt. -* LyX now gives an error if the underlying LaTeX command exited with error. +!!Known issues in version 2.4.0 +* See http://www.lyx.org/trac/wiki/BugTrackerHome -!!Known issues in version 2.2.0 -* LyX needs to be run under Python 2 and will not work properly on systems - where Python 3 is the default binary. See bug #7030 to know how to fix - this properly, since simple shebang conversion in *.py files will not - be enough. +!!Caveats when upgrading from earlier versions to 2.4.x +* LyX now uses the parskip package for vertical paragraph separation. Since the + output differs from the previous (sub-optimal) approach which applied paragraph + separation to sections, lists etc. as well, existing documents + are converted to use preamble code that maintains the previous layout. + The downside is that the workarea looks as if paragraph indendation rather + than paragraph separation was used (output is correct). We encourage you + to try if the new layout suits you, remove the respective preamble code + and re-set the paragraph separation to use the new layout. -!!Caveats when upgrading from earlier versions to 2.2.x +* Autotools monolithic build option for building LyX binaries was removed, + for compilation speedup use parallel building on multiple cores instead. -* BibTeX errors are now processed and cause LyX to show the errors dialog. - Before, these errors were ignored, which means that it may happen that - documents that compiled without error with a previous version now - compile with error. However, because now in 2.2.x users can click on - the "Show Output Anyway" button, the document can still be viewed. +* Several ttf fonts (esint10.ttf, stmary10.ttf, wasy10.ttf) were changed + to reflect the fact that newer Qt libraries do not support displaying certain + codepoints anymore (bug #8493, #10161). + Distribution packagers need to repack those font files in case they are + delivering the fonts as a separated package dependent from core LyX + in order to display correctly math symbols like \oint. -* Missing characters in the output are now reported as errors. This leads - to error reports for documents that compiled without error before. - However, the error was always present but went undetected! + Also note, that while it is still possible to compile LyX against Qt 4 + these math symbols will not be displayed correctly anymore on Qt 4. -* Documents using Times fonts and containing Greek characters may now fail - to compile under pdflatex for users of MikTeX due to an automatically - half-installed "grtimes" package. A workaround in LyX was removed as it - stands in the way of alternative approaches (see bug #6469). +!! If upgrading from a LyX version before 2.3.0 -* With LuaTeX, LyX now uses polyglossia instead of babel if the language - package option "Automatic" is selected. In order to use babel, select - "Always babel" instead. This may be needed if a document uses code that - is specific to babel. +* Please additionally see the release notes from the versions in-between: + https://wiki.lyx.org/LyX/ReleaseNotes
