 ## Notes
 
-This release of the Python agent adds support for [Google Cloud Firestore](https://pypi.org/project/google-cloud-firestore/).
+This release of the Python agent drops support for redis 3 and below and adds support for [Google Cloud Firestore](https://pypi.org/project/google-cloud-firestore/), async [redis](https://pypi.org/project/redis/), and fixes a crash that occurs when wrapping generators.
 
 Install the agent using `easy_install/pip/distribute` via the [Python Package Index](https://pypi.python.org/pypi/newrelic) or download it directly from the [New Relic download site](https://download.newrelic.com/python_agent/release).
 
+## Deprecations
+
+* **Drop support for redis 3 and below**
+  As of 8.10.0, [redis](https://pypi.org/project/redis/3.5.3/) 3 and below are no longer supported. Because redis 4 and above no longer support Python2.7, this means Python2.7 support has been dropped from redis as well.

 ## Enhancements
 
 * **Add support for Firestore**
