 Change Log
 ==========
 
+v2.2.0
+------
+- Support up to clickhouse 20.8
+- Fixed boolean logic for Q objects (https://github.com/Infinidat/infi.clickhouse_orm/issues/158)
+- Remove implicit use of '\N' character (which was causing deprecation warnings in queries)
+- Tooling updates: use poetry, pytest, isort, black
+
+**Backwards incompatible changes**
+
+You can no longer supply a codec for an `alias` field. Previously this had no effect in clickhouse, but now it explicitly returns an error.
+
 v2.1.0

 - Support for model constraints
