+## Release 0.321.0
+
+* Add support for setting the session timezone. When not set explicitly it
+  defaults to the client side local timezone. This changes the behaviour of the
+  client in backward-incompatible way. To preserve the behaviour from client
+  versions older than 0.321.0 you can explicitly pass `timezone='UTC'` to
+  `trino.dbapi.connect` when creating the connection.
+  ([#27](https://github.com/trinodb/trino-python-client/issues/27))
+* Add support for `VARBINARY` query parameters.
+  ([#299](https://github.com/trinodb/trino-python-client/issues/299))
+* Add `Cursor.describe` method to return some metadata about the results of a
+  query.
+  ([#302](https://github.com/trinodb/trino-python-client/issues/302))
+* Add support for variable precision datetime types. This change makes temporal
+  types contain the correct precision as computed by Trino instead of being
+  always limited to millisecond precision.
+  ([#300](https://github.com/trinodb/trino-python-client/issues/300))
