The first feature release of the 5.7 series of NAV is now out!

The source code is available for download at GitHub [1].

New packages for Debian 10 (Buster) and 11 (Bullseye) are available in our APT repository [2] as usual. We haven't started building packages for Debian 12 (Bookworm) yet, but hope to do so by the end of 2023.

Please be extra aware of config file changes. Look out for `*.dpkg-dist` files in `/etc/nav` and make sure to update your running config.

Added =====

- Even more complex and flexible configuration of NAV logging is now supported through logging.yml (#2659)

- Added support for polling and alerting on Juniper chassis and system alerts (#2358, #2388)
