# Release Notes for Cluster Management API 22.08.1

Cluster Management API (CMAPI) 22.08.1 is a maintenance release of CMAPI. CMAPI is a REST API for administering [MariaDB ColumnStore](https://github.com/mariadb-corporation/docs-release-notes/blob/test/en/mariadb-columnstore/README.md) in multi-node topologies.

Cluster Management API 22.08.1 was released on 2022-09-12. This release is of General Availability (GA) maturity.

CMAPI 22.08.1 is compatible with MariaDB ColumnStore 22.08. CMAPI 22.08.1 was first released with [MariaDB ColumnStore 22.08.1.](/docs/release-notes/columnstore/22.08/22.08.1.md)

## Notable Changes

* CMAPI configures ColumnStore to allow read queries to be executed on any node. ([MCOL-4770](https://jira.mariadb.org/browse/MCOL-4770))
  * In previous releases, CMAPI only added an `ExeMgr` section for the primary node to `Columnstore.xml`.
  * Starting with this release, CMAPI adds an `ExeMgr` section for every node to `Columnstore.xml`, which means that any node can execute read queries.
* Since ColumnStore 22.08 merges the `ExeMgr` process into the PrimProc process, CMAPI no longer tries to start ExeMgr on a node when the binary is not present. ([MCOL-5138](https://jira.mariadb.org/browse/MCOL-5138))
* Some redundant log messages have been removed from the CMAPI log. ([MCOL-5157](https://jira.mariadb.org/browse/MCOL-5157))
