# Release Notes for Cluster Management API 1.6.2

Cluster Management API (CMAPI) 1.6.2 is a maintenance release of CMAPI. CMAPI is a REST API for administering [MariaDB ColumnStore](/docs/analytics/mariadb-columnstore.md) in multi-node topologies.

Cluster Management API 1.6.2 was released on 2022-02-23. This release is of General Availability (GA) maturity.

CMAPI 1.6.2 is compatible with MariaDB ColumnStore 5.6 and 6. CMAPI 1.6.2 was first released with [MariaDB ColumnStore 5.6.5](/docs/release-notes/columnstore/old-releases/mariadb-columnstore-5-6-release-notes/mariadb-columnstore-5-6-5-release-notes.md) and [MariaDB ColumnStore 6.2.3.](/docs/release-notes/columnstore/old-releases/mariadb-columnstore-6-release-notes/mariadb-columnstore-6-2-3-release-notes.md)

## Notable Changes

* Compatibility added for MariaDB ColumnStore 6.2.3. ([MCOL-4954](https://jira.mariadb.org/browse/MCOL-4954))
* Compatibility added for ColumnStore 6.2.3 cross engine join encrypted passwords. ([MCOL-4978](https://jira.mariadb.org/browse/MCOL-4978))
* Added support for using a custom port for cross engine join support. ([MCOL-4898](https://jira.mariadb.org/browse/MCOL-4898))

## Issues Fixed

* During upgrade CMAPI configuration information is lost. Customer data is not impacted. ([MCOL-4979](https://jira.mariadb.org/browse/MCOL-4979))
* `mcsStatus` incorrectly returns `"cluster_mode": null`. This is a cosmetic issue that does not affect operation. ([MCOL-4973](https://jira.mariadb.org/browse/MCOL-4973))
