[ANNOUNCE] INN 2.7.3 available

Internet Systems Consortium is pleased to announce that a new minor
release of INN is available at:

    https://downloads.isc.org/isc/inn/inn-2.7.3.tar.gz

An OpenPGP signature of this release is present in the same directory.  A
diff from the previous release are readily available either using Git
commands or from the GitHub release page at:

    https://github.com/InterNetNews/inn/releases/tag/2.7.3

This is a bug-fix and minor feature release over 2.7.2. Upgrading an
existing INN 2.7.2 installation is as simple as building INN 2.7.3,
running make update, and restarting innd and related programs.

Many thanks to Julien ÉLIE for preparing this release.

Changes in 2.7.3:

 * An up-to-date moderators file is provided with this release. It
   basically removes the records of defunct hierarchies. You may want to
   manually update your configuration with the new file.

 * actsyncd now supports fetching a remote active file from a web site,
   using the HTTP or HTTPS protocols. Two new keywords, *path* and
   *protocol*, permit parameterizing that in the actsync.cfg
   configuration file. See the actsync(8) manual page and the updated
   actsync.cfg sample file for more details.

   If you are currently using actsyncd to synchronize your active file
   with the one of an FTP server, please check that FTP access is still
   working and the remote active file is up to date. You are otherwise
   encouraged to update your actsync.cfg configuration file to use an
   HTTPS access. Just adding "protocol=https" may be enough. The
   rationale behind that is the fact that FTP servers are considered less
   secure nowadays; FTP access to "ftp.isc.org" is doomed to be shut down
   one day in favour of HTTPS. The updated actsyncd and simpleftp
   programs shipped with INN go along with the upcoming change.

 * simpleftp, only used by actsyncd, now supports fetching files from web
   servers, using the HTTP(S) protocol. It now also correctly parses a
   port number following a hostname (separated by a colon), and
   establishes FTP sessions in passive mode as this mode works better
   behind firewalls and NAT configurations.

 * Added bzip2 support to actsyncd to uncompress downloaded active files.

 * Fixed syntax warnings in the default filter_innd.py Python hook so
   that innd no longer logs errors with Python 3.12 and greater. Thanks
   to Roberto Corrado for the patch.

 * The check for a fully qualified domain name for the local host at
   startup still produces a warning in the logs but is no longer fatal.
   The installation of INN was otherwise failing under some circumstances
   like when creating a Docker image. Additionally, the INN_HOSTNAME
   environment variable, if set and fully qualified, is now taken by INN
   as the hostname.

 * Several improvements have been made to readership statistics reported
   by innreport: IPv6 addresses are now correctly recognized and reported
   as unresolved instead of unknown, statistics by domain are at a better
   granularity, totals are correctly computed, and only the top 100
   entries are displayed by default instead of a possibly very long
   exhaustive list.

 * Fixed the computation of idle time in the nnrpd timers gathered by
   innreport, and the display of non-printable characters in the section
   about unrecognized NNRP commands. The wording and the case of the
   section titles are also more homogenized.

 * Fixed the handling of empty Message-IDs in perl-nocem. Instead of
   dying, it now just discards these invalid entries.

 * Improved Perl code readability and quality by enforcing the most
   interesting and useful "Perl::Critic" policies. A new "make
   code-check" command has been added to run the checks against the
   source code.

 * Spelling fixes in documentation. Thanks to Christian Clauss for the
   run of codespell.

 * Move the manual pages of delayer, shlock and sm to section 8 (system
   administration commands) instead of section 1 (user commands).

 * Update from GNU Libtool 2.4.7 to 2.5.4.
