---

New features: * Polyglossia now uses the Harfbuzz renderer by default with LuaTeX output. This brings LuaTeX on par with XeTeX for all scripts (#337). The renderer can be changed via the new global luatexrenderer option. * The (previously inadvertently working) hyphenrules environment that ceased to work after a recent babel update is back and now officially supported. The environment now also supports language options and aliases (#427). * New command \setlanghyphenmins to adapt hyphenation thresholds of languages and varieties. * New command \abjadalph for Arabic with corresponding option (#431). * Replace consecutive glues around punctuation by the correct amount of space with LuaLaTeX for French, ecclesiastic Latin, and Sanskrit (#437). Bug fixes: * Remove warning about missing Brazil patterns (#404). * Fix incompatibility with recent babel release (#408). * Fixed some spellings in Marathi (#409). * Fix spacing of geminating dot in Catalan (#410). * Fix incompatibility of Marathi with Beamer. * Correct \partname in Hindi (#416). * Updates and improvements to Kurdish (#418). * Only activate shorthand character if babelshorthands is true (#421). * Fix whitespace issue in Czech and Slovak with vlna=true (#423). * Fix whitespace issue in Danish (#424). * Fix catcode conflicts that might occur in language definition files f. ex. when loaded from a LaTeX3 class (#67, #425). * Robustify font family switches (#428). * Fix whitespace issue in Russian indentfirst option (#433). * In Russian, indentfirst is now again default (#434). * Fix LaTeX error with arabic numbering in Ukrainian (#440). * Fix directionality after Hebrew decimal numbers (#441). * Fix babelname of Latin Serbian (#442). * Fix recording of secondary languages in \xpg at bloaded and \xpg at bcp@loaded lists (#443). * Simplify and robustify section heading modification in Russian and introduce option forceheadingpunctuation (#444). * Fix Cyrillic dash (via babelshorthand "---) when TeX ligatures are disabled (#445) * Fix problem with large character indices in Lua module for punctuation spacing Interface and defaults changes: * Polyglossia now uses the Harfbuzz renderer by default with LuaTeX output. See new features section. Build fixes: * Fix a bug in the dtx build script which was the reason for an utterly incomplete polyglossia.dtx file (#420).
