+### Breaking changes to the experimental async client
+
+The async client is experimental, so these changes do not cause a major version bump. If you use `AsyncLDClient` with hooks or plugins, update your code:
+
+* Remove the experimental `AsyncHook` class. The async client now uses the same synchronous `Hook` class as the sync client. Change each `AsyncHook` subclass to subclass `Hook`, and change its `async def` stages to `def`. The stages run on the event loop, so they must not block. ([#548](https://github.com/launchdarkly/python-server-sdk/issues/548)) ([2457311](https://github.com/launchdarkly/python-server-sdk/commit/2457311781966096c8553f054b03c7667b0b3996))
+* `AsyncPlugin.get_hooks` now returns a list of `Hook` instances. `AsyncPlugin.register` stays async. ([#548](https://github.com/launchdarkly/python-server-sdk/issues/548)) ([2457311](https://github.com/launchdarkly/python-server-sdk/commit/2457311781966096c8553f054b03c7667b0b3996))
+
+
+### Features
+
+* Accept synchronous hooks on the async client ([#548](https://github.com/launchdarkly/python-server-sdk/issues/548)) ([2457311](https://github.com/launchdarkly/python-server-sdk/commit/2457311781966096c8553f054b03c7667b0b3996))
+
+
+### Bug Fixes
+
+* Run after-evaluation hooks when an async evaluation is cancelled or raises ([2457311](https://github.com/launchdarkly/python-server-sdk/commit/2457311781966096c8553f054b03c7667b0b3996))
