syslog-ng provides RPM and DEB package repositories for Ubuntu, Debian, and RHEL, for both amd64 and arm64 architectures.

We also provide ready-to-test binaries in Docker containers based on the current stable Debian image.

Highlights

• affile: add support for filesize based logrotation

  Config file example:

  destination d_file_logrotate {
      file("/my-logfile.log", logrotate(enable(yes), size(30KB), rotations(5)));
  };
  

  (#5191)

Features

• filter: Add a blank filter that test if a value is blank. A value is considered blank if it is not set, is an empty string, is an empty list, is a string with only whitespace, or is boolean false.
  (#5425)

• http-destination: add msg_data_in_header option to be able to turn off sending message content-related data in the HTTP header
  (#5455)

• stats-exporter: Add stats-without-orphaned() and stats-with-legacy() options to further filter the stats output.
  (#5424)

• affile: Add ability to refine the wildcard-file() filename-pattern() option with exclude-pattern(), to exclude some matching files. For example, match all *.log but exclude *.?.log.
  (#5416)

Bugfixes

• afprog: Fix invalid access of freed log-writer cfg.
  (#5445)

• s3: Fixed bug where in certain conditions finished object buffers would fail to upload.
  (#5447)

• stats-exporter: Fix leaks caused by missing "virtual destructor" calls.
  (#5441)

• wildcard-file: Fix possible act_tracker crash caused by duplicated file change notification handler invocation.
  (#5437)

Packaging

• packaging: New package formats, platforms, and architectures!

• the long-awaited RPM repository is here, we have RHEL-8, RHEL-9, and REHL-10 packages available, both for amd64 and arm64 architectures,
  just download and install the repository definition

  sudo curl -o /etc/yum.repos.d/syslog-ng-ose-stable.repo https://ose-repo.syslog-ng.com/yum/syslog-ng-ose-stable.repo

• we fixed the publishing of our arm64 DEB packages

• added new DEB packages for Debian Trixie, both for amd64 and arm64.

• new DBLD docker images for Rocky-9, OpenSuse Tumbleweed, Ubuntu Plucky, and Debian Trixie
  (#5449)

Notes to developers

• mongo-c: now we can build against both the v1 and v2 versions of the mongo-c driver automatically
  (#5442)

• manpages: Finally, we have added manpage generation to the CMake builds as well. The new single source of truth solution can either use the sometimes more up-to-date version from the documentation, or, by default, the locally available ready-to-use instance (which is also synced from the online version, but may lag behind). This can be controlled via the --with-mapages=local|remote, or the -DWITH_MANPAGES=LOCAL|REMOTE configuration options.
