Subject: [gnutls-help] guile-gnutls-3.7.10 released [stable]
Message-ID: <m2o7te8xz0.fsf@fika.lan>

Guile-GnuTLS provides Guile bindings for the GnuTLS library.

Project homepage:
  https://gitlab.com/gnutls/guile

The release is available here:
  https://gitlab.com/gnutls/guile/-/releases/v3.7.10

Documentation:
  https://gnutls.gitlab.io/guile/manual/
  https://gnutls.gitlab.io/guile/manual/gnutls-guile.pdf

Here are the compressed sources and a GPG detached signature:
  https://gitlab.com/gnutls/guile/uploads/2cd9acdf9944191c55048a3b0116f5cf/guile-gnutls-3.7.10.tar.gz
  https://gitlab.com/gnutls/guile/uploads/8eab68830f9064ba6e98bc22bd2ad719/guile-gnutls-3.7.10.tar.gz.sig

Here are the SHA1 and SHA256 checksums:

4b5ca1917e112d8c50301a14f206bca53e844743  guile-gnutls-3.7.10.tar.gz
EprRR1JqmFYkQkwuT0dw8fVtYVG8Ku712LD8Vr6oRd4  guile-gnutls-3.7.10.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 guile-gnutls-3.7.10.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 <simon at 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 simon at josefsson.org

  gpg --recv-keys 51722B08FE4745A2

  wget -q -O- 'https://savannah.gnu.org/project/release-gpgkeys.php?group=guile-gnutls&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 guile-gnutls-3.7.10.tar.gz.sig


This release was bootstrapped with the following tools:
  Autoconf 2.71
  Automake 1.16.5
  Gnulib v0.1-5551-g1db9041826
  Makeinfo 7.0

NEWS

* Noteworthy changes in release 3.7.10 (2022-11-10) [stable]

** Gnulib is used to improve code-reuse and maintainability.
Closes: #1.

** Build fixes wrt static libraries and GNUTLS_CFLAGS.

Happy hacking,
Simon

Hi Ludovic,

I pushed out 3.7.10 to improve maintainer rules a bit.  Would you like
to make a 3.7.11 shortly?  To test the release process and get your
OpenPGP key into distributions' keyring.  I'm hoping the process is just
1) clone repository, 2) ./bootstrap, 3) follow README-release.
