 ====  Improvements
+* `ProxyDataSource#close` to unwrap and delegate `close` to underlying `DataSource` if needed (https://github.com/jdbc-observations/datasource-proxy/issues/129[Issue-129]).
++
+When `ProxyDataSource#close` is called, and the original `DataSource` does not implement `Closeable` or `AutoCloseable`, the proxy now attempts to unwrap the original `DataSource` to one that does, in order to delegate the `close` call appropriately.
