 ### Added
 
 - Use `jwks_url` as a fallback if the `jwks_uri` is not defined in the configuration.
   This makes it possible to use a broader selection of JWT providers.
+- Added `AsyncKeyFetcher.aclose` method to close fetcher's http client directly.
+- Updated http client to use acloseable context manager, so it can be used with
+  `async with` to ensure resources are cleaned up properly.
 
 ### Removed
