Read this when you need to publish or unpublish multiple entries and assets together to a specific environment. ## About Releases You can define a “Release” as a set of [entries](https://www.contentstack.com/docs/content-managers/working-with-entries/about-entries/) and [assets](https://www.contentstack.com/docs/content-managers/working-with-assets/about-assets/) that needs to be deployed ([published](https://www.contentstack.com/docs/content-managers/working-with-entries/publish-an-entry/) or [unpublished](https://www.contentstack.com/docs/content-managers/working-with-entries/unpublish-an-entry/)) all at once to a particular [environment](https://www.contentstack.com/docs/developers/set-up-environments/about-environments/). If you are using a CMS to manage and publish your content, you know that publishing large amounts of time-sensitive content (for example, when there’s a product launch, press release, or sales promotion) is a daunting task. You have to publish multiple entries/assets and their publishing status, and, in most cases, you have to find and keep track of the content pieces one by one. This is a time-consuming process and is prone to errors. Releases dramatically simplify this task for you. All you need to do is simply pin all the required entries and assets to a “Release.” When you deploy this Release, all the pinned items are published/unpublished at the same time to whatever environment you choose. ## Tutorial Video **Note:** To use Releases with web framework, you will need contentstack-express version 3.1.9 or above.
