+## Upgrade notes
+
+- AirPostgres requires Air 0.49 or later. Applications migrating from Air's
+  former built-in PostgreSQL integration should create an `AirPostgres`
+  instance explicitly and attach its lifespan to the application.
+- Version 0.1.0 contained only the generated project scaffold. Version 0.2.0 is
+  the first release that provides the backend described by the package name.
