Releases

Introduced in GitLab 11.7.

It's typical to create a Git tag at the moment of release to introduce a checkpoint in your source code history, but in most cases your users will need compiled objects or other assets output by your CI system to use them, not just the raw source code.

GitLab's Releases are a way to track deliverables in your project. Consider them a snapshot in time of the source, build output, and other metadata or artifacts associated with a released version of your code.

At the moment, you can create Release entries via the Releases API; we recommend doing this as one of the last steps in your CI/CD release pipeline.

Getting started with Releases

Start by giving a description to the Release and including its assets, as follows.

Release description

Every Release has a description. You can add any text you like, but we recommend including a changelog to describe the content of your release. This will allow your users to quickly scan the differences between each one you publish.

NOTE: Note: Git's tagging messages and Release descriptions are unrelated. Description supports markdown.

Release assets

You can currently add the following types of assets to each Release:

  • Source code: state of the repo at the time of the Release
  • Links: to content such as built binaries or documentation

GitLab will support more asset types in the future, including objects such as pre-built packages, compliance/security evidence, or container images.

Source code

GitLab automatically generate zip, tar.gz, tar.bz2 and tar archived source code from the given Git tag. These are read-only assets.

Links

A link is any URL which can point to whatever you like; documentation, built binaries, or other related materials. These can be both internal or external links from your GitLab instance.

NOTE: NOTE You can manipulate links of each release entry with Release Links API

Releases associated with milestones

Introduced in GitLab 12.5.

Releases can optionally be associated with one or more project milestones by including a milestones array in your requests to the Releases API.

Releases display this association with the Milestone indicator near the top of the Release block on the Project overview > Releases page.

A Release with one associated milestone

Below is an example of milestones with no Releases, one Release, and two Releases, respectively.

Milestones with and without Release associations

This relationship is also visible in the Releases section of the sidebar when viewing a specific milestone. Below is an example of a milestone associated with a large number of Releases.

Milestone with lots of associated Releases

Navigate to Project > Releases in order to see the list of releases for a given project.

Editing a release

Introduced in GitLab 12.5.

To edit the details of a release, navigate to Project overview > Releases and click the edit button (pencil icon) in the top-right corner of the release you want to modify.

A release with an edit button

This will bring you to the Edit Release page, from which you can change some of the release's details.

Edit release page

Currently, it is only possible to edit the release title and notes. To change other release information, such as its tag, associated milestones, or release date, use the Releases API. Editing this information through the Edit Release page is planned for a future version of GitLab.

Notification for Releases

Introduced in GitLab 12.4.

You can be notified by email when a new Release is created for your project.

To subscribe to these notifications, navigate to your Project's landing page, then click on the bell icon. Choose Custom from the dropdown menu. The following modal window will be then displayed, from which you can select New release to complete your subscription to new Releases notifications.

Add release notes to Git tags

You can add release notes to any Git tag using the notes feature. Release notes behave like any other markdown form in GitLab so you can write text and drag and drop files to it. Release notes are stored in GitLab's database.

There are several ways to add release notes:

  • In the interface, when you create a new Git tag.
  • In the interface, by adding a note to an existing Git tag.
  • Using the GitLab API.

To create a new tag, navigate to your project's Repository > Tags and click New tag. From there, you can fill the form with all the information about the release:

new_tag

You can also edit an existing tag to add release notes:

Release Evidence

Introduced in GitLab 12.5.

Each time a new release is created, specific related data is collected in parallel. This dataset will be a snapshot this new release (including linked milestones and issues) at moment of creation. Such collection of data will provide a chain of custody and facilitate processes like external audits, for example.

The gathered Evidence data is stored in the database upon creation of a new release as a JSON object. In GitLab 12.5, a link to the Evidence data is provided for each Release.

Here's what this object can look like:

{
  "release": {
    "id": 5,
    "tag": "v4.0",
    "name": "New release",
    "project_id": 45,
    "project_name": "Project name",
    "released_at": "2019-06-28 13:23:40 UTC",
    "milestones": [

          }
        ]
      },
