[2.9.0] - 2026-04-29

[hmpf]

Frontend changes

This time around there are plenty small improvements to the planned maintenance
subsystem.

There's several small changes to the dashboard. Most importantly there's a spot
for more complex, dashboard-only, filters. First one out is a filter to hide incidents that
are "closed" AND "acked". Click on "Special filters".

It is now no longer necessary to use the Django admin for administering
sources. If a user has the is_staff flag set (easiest via Django admin) they
can easily administer sources and their tokens via some new pages accessible
via the user dropdown.

There's a new management command to check for new versions of argus-server, we
hope to eventually be able to have a subscription/notification service for
this. The command is check_version. See also the new app
argus.versioncheck if you are curious.

The styling of the fixed banner (via the BANNER_MESSAGE setting) has changed.

Less visible things

We now include a new notification plugin, for Slack. This is based on the 3rd
party library apprise. Remember to upgrade dependencies!

Finally, we have started to implement heart beat functionality. For a proper
heart beat functionality the glue services must be able to explicitly send
a heart beat, currently we only keep track of when a source (via a glue
service) last used the API.

Note:

We have changed the database backend to psycopg (from psycopg2). If you
have not altered the default database settings you need only install the new
dependency. Otherwise, see NOTES.md for details.

We have replaced the included "light" and "dark" themes with themes based on
the Sikt palette. The new ones have better contrast. To get the old themes
back, see NOTES.md.

While we have added support for running on Python 3.14, there has been some
trouble in practice, so hold off on upgrading Python for now.
