The following packages have been upgraded in the Cygwin distribution:
* libidn2 2.3.4
* libidn2_0 2.3.4
* libidn2-devel 2.3.4
* libidn2-doc 2.3.4
* mingw64-x86_64-libidn2 2.3.4
* mingw64-i686-libidn2 2.3.4
International Domain Name library encodes and decodes Internationalized
Domain Names implementing IETF IDN WG Stringprep, Punycode, IDNA2008,
and Unicode TR46 specifications.
Mingw packages provide MS VC RT-linked binaries, NOT Cygwin binaries,
for use with the mingw64-{x86_64,i686}-gcc cross compiler, installed in
/usr/{x86_64,i686}-w64-mingw32/sys-root/mingw/{bin,lib,include}/.

Noteworthy changes in release 2.3.4 (2022-10-23) [stable]
* Support for Unicode 15.0.0.
We now use Unicode.org's IDNA2008 tables rather than IANA's.
See <https://gitlab.com/libidn/libidn2/-/issues/112> and
<https://lists.gnu.org/archive/html/help-libidn/2022-10/msg00000.html>
for rationale, which can be summarized into
1) IANA are still on 2019-era Unicode version 12 and we wish to
support Unicode version 12-15,
2) consistency with some other implementations,
3) the only incompatibility related to U+19DA is deemed to have minor
real-world consequences.
Thus we break backwards compatibility for U+19DA in this release
compared against libidn2 0.11..2.3.3 thus reverting back to the
libidn2 <= 0.11 behaviour.
We decided to not bump ABI version and believe this is the best choice
going forward as well for minor internal non-API related ABI changes.
* Gnulib updated and now libunistring-optional is used.
This allows you to force libidn2 to use internal libunistring with the
following command: ./configure --with-included-libunistring
