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

https://downloads.isc.org/isc/inn/inn-2.7.1.tar.gz

As of this release, we're only providing the tarball and a PGP signature
(in the same directory) without the extra hashes and signed hashes. The usefulness of the additional files seemed questionable.

Since INN is now developed using Git, diffs 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/2.7.1

We are therefore no longer generating a full diff and including it in the release directory.

This is a bug-fix and minor feature release over 2.7.0. Upgrading an
existing INN 2.7.0 installation is as simple as building INN 2.7.1,
running make update, and restarting innd and related programs.

Many thanks to Julien ÉLIE for preparing this release.

Changes in 2.7.1:

* Added a new *groupexactcount* parameter in readers.conf to force nnrpd
to report the exact number of still existing articles in newsgroups
instead of an estimated count. When the estimated number of articles
is strictly below *groupexactcount* (set to 5 by default), nnrpd now
recounts them and reports the actual value (articles that have been
cancelled or overwritten in self-expiring CNFS buffers may otherwise
still be counted in the estimate). News clients will then be directly
aware of empty newsgroups; they would otherwise have tried to retrieve
possible articles, to finally not show anything to the user.

* Programs sending mails now include, when appropriate, an
Auto-Submitted header field in the message headers (either set to
"auto-generated" or "auto-replied", following the recommendation in
RFC 3834). Thanks to Harald Dunkel for this suggestion which will for
instance help to avoid unnecessary vacation replies.

* Added a new -a option to innmail to specify additional header fields
to add in the headers of messages. This is notably used to internally
support the addition of the Auto-Submitted header field in outgoing
mails.

* Added new ovsqlite-util program to perform some basic consistency
checks and dump operations on an overview database using the ovsqlite
method. More checks and features will be added in future releases.
You'll need the "DBI" Perl module with the "DBD::SQLite" driver
installed on your system to use this program.

* Added TLS support in pullnews for connections to upstream servers
configured in pullnews.marks, and to the downstream server in the
existing -s flag. A port can now also be specified for connections to
upstream servers (it was already possible for the downstream server
only).

* Added a new -L option to pullnews to specify the largest wanted
article size in bytes. Articles whose size exceeds that value will no
longer be downloaded by pullnews.

* pullnews now detects a socket timeout while downloading articles from
a remote peer. The download gracefully stops, and another attempt can
be automatically made according to the setting given with the -t flag.
Thanks to Jesse Rehmer for the bug report.

* Fixed the generation and the handling of storage tokens on wrapped
CNFS buffers, thanks to bug reports from Kamil Jonca:

* Duplicate entries were returned by makehistory on fully wrapped
cyclic buffers (the first article of the cyclic buffer appeared
twice in the output).

* The first article of a fully wrapped cyclic buffer was removed too
soon from history (expire wrongly thought its storage token was no
longer existing after a wrap).

* The first article of the previous cycle number of a cyclic buffer
containing articles from two different cycle numbers was wrongly
considered by makehistory to belong to the current cycle number.

* innd no longer dies when a newsfeeds entry has an unexpected trailing
whitespace.

* The size of duplicated articles was counted twice in totals, average
article sizes and graphs by innreport, when parsing innd checkpoints.
Thanks to Hauke Lampe for the patch to count it only once.

* Customizing the domain part of Message-IDs generated by nnrpd and the
server name indicated in Injection-Info header fields is now easier:
the *domain* parameter in the access blocks of readers.conf can be
directly used (without needing to set *virtualhost* as it was
previously the case).

* If the *domain* parameter is set in inn.conf or in a readers.conf
access block, and has invalid characters, or if the fully qualified
domain name (FQDN) of the news server has invalid characters when
*domain* is unset, a fatal error is now reported at startup. It is a
basic configuration error which otherwise leads to the generation of
invalid article Message-IDs.

* Improved the speed of article searches with HDR, LAST, NEXT, and XPAT
commands when there is a (huge) gap in article numbers. On newsgroups
with several millions of consecutive missing articles (which is a rare
situation), these commands could take several seconds to run.

* Incoming articles in newsgroups that have exceeded the maximum number
of articles they can contain (2^31-1) are now correctly rejected. INN
was otherwise happily accepting them but either numbers returned in
NNTP responses were not right, or some news clients choked when
receiving unexpected large article numbers. (The current version of
the NNTP protocol only allows article numbers up to 2^31-1.)

* Fixed the renumbering of reported low water marks for empty newsgroups
in active after overview expiration, when using the ovsqlite method.
They were set to 1 for empty newsgroups whereas they were not supposed
to decrease. (These reported low water marks regained their expected
values during the next overview expiration, provided that the
newsgroup was no longer empty.)

* The reported high water mark of empty newsgroups is now correctly set
to one less than the reported low water mark in overview data.
(Previously, the reported low water mark was set to one more than the
reported high water mark.)

* Fixed the output of the "ctlinnd feedinfo ''" command that was
returning information only for the first site, and the output of the
"ctlinnd name channel" command that was returning partial information
for the requested channel.

* The build of external programs which include inn/storage.h was failing
because of the unexpected inclusion of config.h in one of the included
headers. Also, a few Autoconf results were not correctly made
available to external programs. This is now fixed.

* Fixed the build on systems whose default shell does not completely
meet the Posix standard. A few build scripts were run with the
default shell instead of the one found by Autoconf and afterwards used
for INN.

* Use standard daemon(3) C function, when available, to daemonize innd,
nnrpd, ovdb_server and ovsqlite-server instead of an INN-specific
function.
