Percona Monitoring and Management (PMM) is a free and open-source platform for managing and monitoring MySQL, MongoDB, and PostgreSQL performance.

## Release Highlights

- Custom certificates help define proper security levels for remotely monitored MySQL instances, including Google Cloud SQL.

- Usability improvements to the External Monitoring UI. When filling parameters, you can enter the parts of an endpoint (scheme, host, path) or let PMM automatically extract them from a URL.

- pg_stat_monitor 0.9.0 support. This change will give you compatibility with the latest version. Support for new features will be in an upcoming release.

- Single-line install of PMM Server on supported Linux distributions (this feature is in Technical Preview).

- DBaaS Changes: (this feature is in Technical Preview)
    - It is easier to experience DBaaS functionality; you can quickly turn it ON/OFF in *Advanced settings* on the *Settings* page. ([Read more](../how-to/configure.md#advanced-settings))
    - Database components management will enable PMM administrators to limit users in your organization to specific (admin-approved) database versions in their DBaaS DB Clusters.
    - For PXC clusters created using DBaaS, HAProxy will now be used by default.  Please note: Monitoring of the HAProxy in DBaaS will be enabled in an upcoming release.

- Changes to *Sign in to Percona Platform*. From this release, Registration of the Percona account will be more secure and require additional confirmation.
