Release Highlights

Grafana Upgrade Embedded Grafana version was upgraded from 7.5.7 to 7.5.11 to improve some Grafana instrumentation metrics. Also, the upgrade is delivering a security fix that impacted Grafana. Please upgrade to the latest version of PMM ASAP. Read more about CVE issue here
Backup Management (Technical preview):
- An ability to view logs of the backup process for better visibility over the backup process
- An ability to schedule Point-In-Time-Recoverable backup from MongoDB clusters with the correct configuration. Note: there is no UI to restore PITR for MongoDB at the moment. It will come with future releases, but it is possible to restore a PITR backup with Percona Backup for MongoDB manually
DBaaS (Technical preview): From this release on, PMM users who are using the DBaaS feature will be able to update versions of their DBaaS controlled Databases by the push of a button according to each DB's compatibility matrix.
Please note that we recently found a bug PMM-8723 that was causing significant problems with DBaaS usage. This bug was fixed in this release, and no additional actions will be required.
