## 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. |
