The updated [Docker Subscription Service Agreement](https://www.docker.com/legal/docker-subscription-service-agreement) includes a change to the terms for **Docker Desktop**. - Docker Desktop **remains free** for small businesses (fewer than 250 employees AND less than $10 million in annual revenue), personal use, education, and non-commercial open source projects. - It requires a paid subscription (**Pro, Team, or Business**), for as little as $5 a month, for professional use in larger enterprises. - The effective date of these terms is August 31, 2021. There is a grace period until January 31, 2022 for those that will require a paid subscription to use Docker Desktop. - The Docker Pro and Docker Team subscriptions now **include commercial use** of Docker Desktop. - The existing Docker Free subscription has been renamed **Docker Personal**. - **No changes** to Docker Engine or any other upstream **open source** Docker or Moby project. To understand how these changes affect you, read the [FAQs](https://www.docker.com/pricing/faq). For more information, see [Docker subscription overview](../subscription/_index.md). ### Upgrades - [Compose V2 RC2](https://github.com/docker/compose-cli/releases/tag/v2.0.0-rc.2) - Fixed project name to be case-insensitive for `compose down`.
