### JKS Keystore Minimum Password Length

[JKS Keystores][jks-keystore] now have a minimum password length of 6 characters,
ℹ️ This no longer applies as it was fixed in `v1.6.1`, but will remain here for
informational purposes. If you haven't upgraded cert-manager to `v1.6.0` from any `v1.5`
release, we recommend upgrading straight to the latest version, skipping `v1.6.0`.

In cert-manager `v1.6.0` [JKS Keystores][jks-keystore] had a minimum password length of 6 characters,
as an unintended side effect of [upgrading keystore-go from `v2` to `v4`][jks-keystore-upgrade-pr].
If you are using a shorter password, certificates will fail to renew,
and the only observable error will be in the cert-manager logs.
We are discussing the best remediation for a future `v1.6.1` release.
If you are using a shorter password, certificates would have failed to renew,
and the only observable error was in the cert-manager logs.
This was fixed in cert-manager `v1.6.1`.
