# Breaking changes

Here we address changes that may cause previously working configurations to stop working after the update, if they are not adjusted to handle the changes below.

### Updated default encryption

As of 3.1.0 default encryption has been changed. This will only affect systems where encryption is enabled.

To keep previous implementation ensure environment setting:

FORTIFIED\_SECRETS\_IMPL = local<br>

### 3.0.0

### Best Practice Configuration Recommendation

While it is possible to upgrade and continue using the previous configuration, we strongly recommend updating to the new configuration outlined in the *Release Notes*.
