+## [2.2.0] - 2025-08-26
+
+The most important bit of this release is the new (old) way to install and set
+up argus-server, including the frontend. Please see the NOTES.
+
+### Added, frontend
+
+- Added option 'Last 3 days' to the Timeframe selector.
+  ([#1440](https://github.com/Uninett/Argus/issues/1440))
+
+### Added
+
+- Added rule to Makefile that downloads standalone tailwind CLI client as per
+  the version configured in `src/argus/htmx/tailwindtheme/config.py`.
+  ([#1531](https://github.com/Uninett/Argus/issues/1531))
+- Add a fledgling CONTRIBUTING.rst for onboarding new developers.
+- Added documentation for the rules in the `Makefile`.
+- Two new development howtos have been added, with tips for using git and
+  GitHub.
+
+### Changed
+
+- Make example production Docker image work properly for Argus 2
+- The settings files have changed, since the HTMx frontend app is now included
+  by default. The frontend settings has been merged in and no longer need the
+  settings overriding machinery. It is no longer necessary to install the
+  frontend with `pip install argus-server[htmx]`, just `pip install
+  argus-server` will do.
+- Updated contributors file with contributors that joined after 2019, and added
+  a howto for how to keep the list updated.

+It is no longer necessary to install the frontend with `pip install

+will still work but is deprecated.
 
-### Added
+The included settings files were using the `update_settings` trick to set up
+the frontend, this has now been fixed. If you do not use separate settings
+files you should not need to do anything, but if you *do* use your own
+settings-files you no longer need invoke `update_settings`, just choose what
+settings-file to import/copy from with care.

-### Changed
+All other changes are related to maintenance and/or development. The rules in
+the Makefile have been documented. A rule for controlling/upgrading the version
+of Tailwind and Daisy UI has been added to the Makefile, and compiling CSS via
+`make tailwind` will be using the versions downloaded with the new rule.
