+## Major Changes
+
+### etcd Upgrade Path
+
+We have changed the default etcd version to `3.5.17`.
+
+You can upgrade by changing your YAML file to use the new Docker Image (`quay.io/coreos/etcd:v3.5.17`).
+
+### MySQL Upgrade Path
+
+With the latest version of Vitess (`v22.0.0`) the default MySQL version changed from `8.0.30` to `8.0.40`.
+
+In order for you to correctly upgrade, there is a certain path to follow:
+
+1. Add `innodb_fast_shutdown=0` to your extra cnf in your YAML file.
+2. Apply this file.
+3. Wait for all the pods to be healthy.
+4. Then change your YAML file to use the new Docker Image (`mysql:8.0.40`).
+5. Remove `innodb_fast_shutdown=0` from your extra cnf in your YAML file.
+6. Apply this file.
