### Upgrade Notes

* When upgrading to 2.3.14+, replace any references to `hash:` with `lmdb:` in your config files.

* When upgrading to 2.4+, there are a lot of gratuitous [config-directive changes](https://doc.dovecot.org/main/installation/upgrade/2.3-to-2.4.html). The Docker image doesn't contain configs but the helm chart provided here has a configmap template that contains the following changes:
