# KCM Version 2.20.1

## Support for EL9 <a href="#support-for-el9" id="support-for-el9"></a>

**KCM-408**: Add EL9 build for Keeper Connection Manager

KCM has historically support EL7 and EL8 versions of Red Hat and derivatives, with EL7 support having been dropped in our previous release. This release introduces package builds and support for EL9.

## Production of SBOMs as part of KCM build <a href="#production-of-sboms-as-part-of-kcm-build" id="production-of-sboms-as-part-of-kcm-build"></a>

**KCM-429**: Produce SBOM for all packages included with Keeper Connection Manager

Each RPM package produced as part of KCM now includes at least one SBOM describing its contents, and the Docker images that contain KCM packages also contain these SBOM files.

The files can be found beneath `/opt/keeper/share` for each relevant component of each KCM package installed.<br>

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.keeper.io/release-notes/enterprise/keeper-connection-manager/kcm-version-2.20.1.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
