 # Changelog
 
+## v0.18.0
+
+0.18 is a big release with 3 main themes:
+* Support only Python 3 and modernize the infrastructure accordingly
+* Metadata API (a low-level API for metadata de/serialization and
+  modification) is now feature-complete for the client use cases
+* ngclient (a new high-level client API) was added. ngclient should be
+  considered an unstable API and is not yet recommended for production
+  use.
+
+Additionally the Github project name changed: project is now "python-tuf"
+instead of "tuf". Redirects are in place for the old name but updating links is
+advised.
+
