[Simon Josefsson]

We are happy to announce the release 2.3.2 of libidn2!

Libidn2 is a free software implementation of IDNA2008, Punycode and
Unicode TR46.  Its purpose is to encode and decode internationalized
domain names.

[*] Use a .sig file to verify that the corresponding file (without the
.sig suffix) is intact.  First, be sure to download both the .sig file
and the corresponding tarball.  Then, run a command like this:

  gpg --verify libidn2-2.3.2.tar.gz.sig

If that command fails because you don't have the required public key,
then run this command to import it:

  gpg --keyserver keys.gnupg.net --recv-keys 0664A76954265E8C

and rerun the 'gpg --verify' command.

NEWS

* 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
<https://gitlab.com/libidn/libidn2/-/issues/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
<https://gitlab.com/libidn/libidn2/-/issues/93>.

** doc: Improve GTK-DOC manual.

** doc: Don't ship HTML/PDF manual.  Drop custom CSS stylesheet.

Happy hacking,
Simon
