Technical notes

This section describes technical changes associated with this release of Grafana.

Use of unencrypted passwords for data sources no longer supported

As of Grafana v8.1, we no longer support unencrypted storage of passwords and basic auth passwords.

{{< admonition type="note" >}} Since Grafana v6.2, new or updated data sources store passwords and basic auth passwords encrypted. However, unencrypted passwords and basic auth passwords were also allowed. {{< /admonition >}}

To migrate to encrypted storage, use a grafana-cli command to migrate all of your data sources to use encrypted storage of secrets. See migrate data and encrypt passwords for further instructions.
