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 red + 'x' next to the spinner to cancel export. Thanks to this functionality, we now + remove the "Stop command?" prompt, which polled users whether to stop a long + process. +* 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. -!!Documents compilation process and images conversion +* Backspace and other forms of deletion 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.) + +* Shift-F3 can 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. + +* When using the document compare function, there is now an option to display the + differences using a special "Document Compare" author. +* InsetRef now supports starred commands. The starred commands stop hyperref from + creating a link (and are only available when hyperref is used). There is a + checkbox "No Hyperlink" for this purpose. +* Alt-Escape can be used to 'float' and redock widgets like the table of contents + or source view. + +* Edit > Paste operation now preserves newlines in text by default. + + +!!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". + +* With LyXHTML output, there are now different CSS classes generated for + different depths: enumi, enumii, enumiii, and enumiv, and similarly for + itemize: lyxitemi, etc. There is also a new HTMLClass tag, which makes it + easier to provide specific classes for paragraphs. + +* HTML support has been updated to output XHTML5 files. A major change is the + use of XML entities instead of HTML ones (e.g., LyX now outputs - + instead of "). + +* 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. + +* Postscript -> PDF convertor (ps2pdf) uses -dALLOWPSTRANSPARENCY by + default now (implemented since ghostscript 9.53.3, see bug #12303). + +* There is a widespread ban on postscript conversions across different + linux distributions and there are currently two way how to address + various image conversion errors when typesetting your documents: + - either manually remove the bans of EPS/PDF coders in ImageMagick + policy.xml configuration file + - or install alternative converters for bitmap <-> postscript. + In particular pdftoppm (poppler-utils) and tiff2ps (libtiff-tools) + are now recognized and activated in case LyX detects ImageMagick + policy ban. These will allow eps<->png(jpg) conversion chain to + be found when processing your documents. + Package maintainers of distributions (e.g. openSUSE or Debian derivates) + where ghostscript conversions of ImageMagick are banned can simply + add dependencies for poppler-utils and libtiff-tools to workaround + the problem. + +* LyX now supports hebrew and hungarian quotation styles. !!!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.
