We are happy to announce a new release of libidn2!

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

Here are the compressed sources and a GPG detached signature:

Use a mirror for higher download bandwidth:

Here are the SHA1 and SHA256 checksums:

b70784b68f29721f5dfff7011014d99247a04112  libidn2-2.3.3.tar.gz
CHsRWqCU0Kef0NBnC7uHqsQdX8jNWBhfzXbgn39XOGM  libidn2-2.3.3.tar.gz

The SHA256 checksum is base64 encoded, instead of the
hexadecimal encoding that most checksum tools default to.

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 libidn2-2.3.3.tar.gz.sig

The signature should match the fingerprint of the following key:

  pub   ed25519 2019-03-20 [SC]
        B1D2 BD13 75BE CB78 4CF4  F8C4 D73C F638 C53C 06BE
  uid   Simon Josefsson <>

If that command fails because you don't have the required public key,
or that public key has expired, try the following commands to retrieve
or refresh it, and then rerun the 'gpg --verify' command.

  gpg --locate-external-key

  gpg --recv-keys 51722B08FE4745A2

  wget -q -O- 
| gpg --import -

As a last resort to find the key, you can try the official GNU

  wget -q
  gpg --keyring gnu-keyring.gpg --verify libidn2-2.3.3.tar.gz.sig

This release was bootstrapped with the following tools:
  Gnulib v0.1-5279-g19435dc207
  Autoconf 2.71
  Automake 1.16.5
  Libtoolize 2.4.6
  Make 4.3
  Makeinfo 6.7
  Help2man 1.48.1
  Gperf 3.1
  Gengetopt 2.23
  Gtkdocize 1.33.1
  Tar 1.34
  Gzip 1.10


* Noteworthy changes in release 2.3.3 (2022-07-11) [stable]

** Upgrade IDNA Tables from Unicode 11 to 12.

** Upgrade TR46 Tables from Unicode 13 to 14.

** Updated gnulib files and various build fixes.
Gnulib's Unicode code claims conformance to Unicode 14.0.0 rather than
Unicode 9.0.0.  A bug in Libidn2's build system was fixed that caused
the system libunistring to be used even though the system version was
too old.

** Self-check improvements.
Self-checks for the idn2 command line tool were added.  Closes: #96.
The C self-checks in tests/ should now be usable outside of the
libidn2 build environment, for system integration checks of a
system-installed libidn2.
