+## What's Changed
+
+Switching to semantic versioning. From this release on, at least the major release number matches
+the most recent Juju supported. Hence the jump to `3.0.0` since this release supports `Juju 3.0`.
+(This also means that `python-libjuju <= 2.9.11` only support up to `Juju 2.x`)
