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: https://ftpmirror.gnu.org/libidn/libidn2-2.3.4.tar.gz https://ftpmirror.gnu.org/libidn/libidn2-2.3.4.tar.gz.sig Use a mirror for higher download bandwidth: https://www.gnu.org/order/ftp.html Here are the SHA1 and SHA256 checksums: 096e2f170fabdfd7011a1848a43e0fca49e3f2e5 libidn2-2.3.4.tar.gz k8q6crTgUdH41PWgdqtjyZt3+u4Bm3K5eDsmeYbbtF8 libidn2-2.3.4.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 libidn2-2.3.4.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 <si...@josefsson.org> 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 si...@josefsson.org gpg --recv-keys 51722B08FE4745A2 wget -q -O- 'https://savannah.gnu.org/project/release-gpgkeys.php?group=libidn2&download=1' | gpg --import - As a last resort to find the key, you can try the official GNU keyring: wget -q https://ftp.gnu.org/gnu/gnu-keyring.gpg gpg --keyring gnu-keyring.gpg --verify libidn2-2.3.4.tar.gz.sig This release was bootstrapped with the following tools: Gnulib v0.1-5534-g2118e7cf12 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 NEWS * Noteworthy changes in release 2.3.4 (2022-10-23) [stable] ** Support for Unicode 15.0.0. Closes: #112. We now uses 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 Happy hacking, Simon
