Noteworthy changes in release 2.3.2 (2021-07-19) [stable]
** Upgrade TR46 tables from Unicode 11 to Unicode 13. Now U+32FF works. Fixes #77.
** Fix build errors related to doc/idn2--help.texi. With older makeinfo, this would manifest itself by looking for idn2-help.texi instead. Further, some BSD grep implementations did not like the + regexp command, so we now rely on the (apparently) more portable * regexp command. Reported-By: David Gessel. See #93.
** doc: Improve GTK-DOC manual.
** doc: Don't ship HTML/PDF manual. Drop custom CSS stylesheet.
