We’re pleased to announce the release of Coder v1.14.0!

This release includes new features like the ability to run system-level applications in your environments, account dormancy, environment variables, UI improvements, security updates, and bug fixes.

## Container-Based Virtual Machines (CVMs)

Coder now allows you to create environments capable of running system-level applications like Docker, Docker Compose, Kubernetes, or systemd. We call this variant of our standard environment a [Container-based Virtual Machine](https://coder.com/docs/environments/cvms#container-based-virtual-machine%20(CVM)). When you choose this option, your environments behave like virtual machines with all of the image, security, and performance properties of typical containers.

## Account Dormancy

Coder now flags accounts that haven’t been used in 90 days as dormant. [Dormant accounts](https://coder.com/docs/admin/account-dormancy) do not count toward your license seats.

You can also set a deletion threshold. After this threshold, Coder will automatically delete dormant accounts (e.g. if you set a deletion threshold of 30 days, Coder will delete accounts that haven’t been used in 120 days).

## Coder Environment Variables

Coder injects a standard set of [environment variables](https://help.coder.com/hc/en-us/articles/360059484653-Working-with-CODER-Environment-Variables) that allow you to access contextual information about your Coder environment.

## UI Improvements

Admin-level users (such as site managers) will notice that we’ve redesigned all of the **Admin** pages.

Improved admin UI in Coder

We’ve also redesigned the toggles in the Coder UI, the Progressive Web App icon, and the **Rebuild Environment** icon.

Other UI changes include the displaying of SSH information (as well as links to educational material) on the environment overview page and improved code blocks.

## Security Updates, Bug Fixes, and Other Under-the-Hood Improvements

We’ve enhanced security around the use of API keys within your environments and fixed an upstream SSH server [DoS vulnerability](https://groups.google.com/g/golang-announce/c/CqSxrm7Mpr0/m/BGVPu5DJAgAJ).
