# CircleCI server v4.2 release notes

## Overview

The v4.2 release introduces the config policies feature to CircleCI server. Use config policies to create organization-level policies to impose rules and scopes to govern which configuration elements are required, allowed, not allowed etc. For more information see the [Config policies overview](https://circleci.com/docs/guides/config-policies/config-policy-management-overview/). To use config policies CLI commands with server, append all commands shown in the docs with `--policy-base-url [https://<CIRCLECI-SERVER-DOMAIN>.com](https://<CIRCLECI-SERVER-DOMAIN>.com)`

The last fully compatible CircleCI CLI version for v4.2 is [v0.1.30549](https://github.com/CircleCI-Public/circleci-cli/releases/tag/v0.1.30549), specifically for operations on self-hosted runners.
