+
+We have been working on a [new version 2.0 of
+MetAlerts](https://api.met.no/weatherapi/metalerts/2.0/documentation), which is
+expected to replace the current version 1.1 in May. A short summary of the most
+important changes:
+
+- New endpoints with a more logical organization
+- A new CAP profile with more data parameters
+- Improved and fully supported location search
+- Improved GeoJSON output with more data
+
+In the new version we have the following endpoints:
+
+    /current - only currently valid alerts
+    /all     - every alert for the last 4 weeks (same as "show=all" in 1.1)
+    /test    - "fake" alerts for test purposes
+    /archive - previously issued alerts since 2019
+
+All endpoints support output in RSS, GeoJSON and CAP (XML) formats. Positional
+search (lat=...&lon=...) works for all endpoints, but is much faster (except for
+/archive). Some features are still marked as experimental, but will become
+stable in May on the official launch.
+
+New parameters have been added, including:
+
+- riskMatrixColor - shows the alert level (yellow/orange/red)
+- incidentName - name of extreme weather for red level alerts (e.g. "Hans")
+- altitude/ceiling - vertical extent of the alert
+
+Also, the [documentation](https://docs.api.met.no/doc/metalerts/MetAlerts.html)
+has been vastly improved. Lists of parameters with explanations are now
+available for both CAP profiles (v1 and v2), and the GeoJSON format now has a
+proper spec, and is not expected to change until the next version.
+
+We hope users will take a look at the new version and update their systems
+before version 1.1 is terminated, probably after the summer. More information
+will be given on the mailing list when the new version is out of beta.
