     Every Git repository has an initial branch, which is named `master` by default. It's the first branch to be created automatically when you create a new repository. Future [Git versions](https://lore.kernel.org/git/pull.656.v4.git.1593009996.gitgitgadget@gmail.com/) will change the default branch name in Git from `master` to `main`. In coordination with the Git project and the broader community, [GitLab has changed the default branch name](https://gitlab.com/gitlab-org/gitlab/-/issues/223789) for new projects on both our SaaS (GitLab.com) and self-managed offerings starting with GitLab 14.0. This will not affect existing projects.

Also, make sure the strategies and environments match the deleted flag. We created a [video tutorial](https://www.youtube.com/watch?v=CAJY2IGep7Y) to help with this migration.

 As mentioned in [13.9](https://about.gitlab.com/releases/2021/02/22/gitlab-13-9-released/#deprecations-for-dependency-scanning) and [this blog post](https://about.gitlab.com/blog/2021/02/08/composition-analysis-14-deprecations-and-removals/) several removals for Dependency Scanning take effect.
 
 Previously, to exclude a DS analyzer, you needed to remove it from the default list of analyzers, and use that to set the `DS_DEFAULT_ANALYZERS` variable in your project’s CI template. We determined it should be easier to avoid running a particular analyzer without losing the benefit of newly added analyzers. As a result, we ask you to migrate from `DS_DEFAULT_ANALYZERS` to `DS_EXCLUDED_ANALYZERS` when it is available. Read about it in [issue #287691](https://gitlab.com/gitlab-org/gitlab/-/issues/287691).

 For self-managed instances using the experimental [external pipeline validation service](https://docs.gitlab.com/ee/administration/external_pipeline_validation.html), the range of error codes GitLab accepts will be reduced. Currently, pipelines are invalidated when the validation service returns a response code from `400` to `499`. In GitLab 14.0 and later, pipelines will be invalidated for the `406: Not Accepted` response code only.

 Legacy feature flags became read-only in GitLab 13.4. GitLab 14.0 removes support for legacy feature flags, so you must migrate them to the [new version](https://docs.gitlab.com/ee/operations/feature_flags.html). You can do this by first taking a note (screenshot) of the legacy flag, then deleting the flag through the API or UI (you don't need to alter the code), and finally create a new Feature Flag with the same name as the legacy flag you deleted. Also, make sure the strategies and environments match the deleted flag. We created a [video tutorial](https://www.youtube.com/watch?v=CAJY2IGep7Y) to help with this migration.

 Until GitLab 13.9, if you wanted to avoid running one particular GitLab SAST analyzer, you needed to remove it from the [long string of analyzers in the `SAST.gitlab-ci.yml` file](https://gitlab.com/gitlab-org/gitlab/-/blob/390afc431e7ce1ac253b35beb39f19e49c746bff/lib/gitlab/ci/templates/Security/SAST.gitlab-ci.yml#L12) and use that to set the [`SAST_DEFAULT_ANALYZERS`](https://docs.gitlab.com/ee/user/application_security/sast/#docker-images) variable in your project's CI file. If you did this, it would exclude you from future new analyzers because this string hard codes the list of analyzers to execute. We avoid this problem by inverting this variable's logic to exclude, rather than choose default analyzers.
 Beginning with 13.9, [we migrated](https://gitlab.com/gitlab-org/gitlab/-/blob/14fed7a33bfdbd4663d8928e46002a5ef3e3282c/lib/gitlab/ci/templates/Security/SAST.gitlab-ci.yml#L13) to `SAST_EXCLUDED_ANALYZERS` in our `SAST.gitlab-ci.yml` file. We encourage anyone who uses a [customized SAST configuration](https://docs.gitlab.com/ee/user/application_security/sast/#customizing-the-sast-settings) in their project CI file to migrate to this new variable. If you have not overridden `SAST_DEFAULT_ANALYZERS`, no action is needed. The CI/CD variable `SAST_DEFAULT_ANALYZERS` has been removed in GitLab 14.0, which released on June 22, 2021.

 As a part of the migration to a common report format for all of the Secure scanners in GitLab, DAST is making changes to the DAST JSON report. Certain legacy fields were deprecated in 13.8 and have been completely removed in 14.0. These fields are `@generated`, `@version`, `site`, and `spider`. This should not affect any normal DAST operation, but does affect users who consume the JSON report in an automated way and use these fields. Anyone affected by these changes, and needs these fields for business reasons, is encouraged to open a new GitLab issue and explain the need.

 To ensure Secret Detection was scanning both default branches and feature branches, we introduced two separate secret detection CI jobs (`secret_detection_default_branch` and `secret_detection`) in our managed [`Secret-Detection.gitlab-ci.yml`](https://gitlab.com/gitlab-org/gitlab/-/blob/master/lib/gitlab/ci/templates/Security/Secret-Detection.gitlab-ci.yml) template. These two CI jobs created confusion and complexity in the CI rules logic. This deprecation moves the `rule` logic into the `script` section, which then determines how the `secret_detection` job is run (historic, on a branch, commits, etc).
 If you override or maintain custom versions of `SAST.gitlab-ci.yml` or `Secret-Detection.gitlab-ci.yml`, you must update your CI templates. We strongly encourage [inheriting and overriding our managed CI templates](https://docs.gitlab.com/ee/user/application_security/secret_detection/#custom-settings-example) to future-proof your CI templates.

 The legacy method of DAST Domain Validation for CI/CD scans was deprecated in GitLab 13.8, and is removed in GitLab 14.0. This method of domain validation only disallows scans if the `DAST_FULL_SCAN_DOMAIN_VALIDATION_REQUIRED` environment variable is set to `true` in the `gitlab-ci.yml` file, and a `Gitlab-DAST-Permission` header on the site is not set to `allow`. This two-step method required users to opt in to using the variable before they could opt out from using the header.

 The [deployment frequency project-level API](https://docs.gitlab.com/ee/api/dora4_project_analytics.html#list-project-deployment-frequencies) endpoint has been deprecated in favor of the [DORA 4 API](https://docs.gitlab.com/ee/api/dora/metrics.html), which consolidates all the metrics under one API with the specific metric as a required field. As a result, the timestamp field, which doesn't allow adding future extensions and causes performance issues, will be removed. With the old API, an example response would be `{ "2021-03-01": 3, "date": "2021-03-01", "value": 3 }`. The first key/value (`"2021-03-01": 3`) will be removed and replaced by the last two (`"date": "2021-03-01", "value": 3`).
 
 ### Remove success and failure for finished build metric conversion

+
 In GitLab Runner 13.5, we introduced `failed` and `success` states for a job. To support Prometheus rules, we chose to convert `success/failure` to `finished` for the metric. In 14.0, the conversion has now been removed. Refer to [issue #26900](https://gitlab.com/gitlab-org/gitlab-runner/-/issues/26900) for details.

 ### Removed Global `SAST_ANALYZER_IMAGE_TAG` in SAST CI template

 With the maturity of GitLab Secure scanning tools, we've needed to add more granularity to our release process. Previously, GitLab shared a major version number for [all analyzers and tools](https://docs.gitlab.com/ee/user/application_security/sast/#supported-languages-and-frameworks). This requires all tools to share a major version, and prevents the use of [semantic version numbering](https://semver.org/). In GitLab 14.0, SAST removes the `SAST_ANALYZER_IMAGE_TAG` global variable in our [managed `SAST.gitlab-ci.yml`](https://gitlab.com/gitlab-org/gitlab/-/blob/master/lib/gitlab/ci/templates/Jobs/SAST.gitlab-ci.yml) CI template, in favor of the analyzer job variable setting the `major.minor` tag in the SAST vendored template.
 
 Each analyzer job now has a scoped `SAST_ANALYZER_IMAGE_TAG` variable, which will be actively managed by GitLab and set to the `major` tag for the respective analyzer. To pin to a specific version, [change the variable value to the specific version tag](https://docs.gitlab.com/ee/user/application_security/sast/#pinning-to-minor-image-version).

 ### Segments removed from DevOps Adoption API
 
+WARNING:

 The first release of the DevOps Adoption report had a concept of **Segments**. Segments were [quickly removed from the report](https://gitlab.com/groups/gitlab-org/-/epics/5251) because they introduced an additional layer of complexity on top of **Groups** and **Projects**. Subsequent iterations of the DevOps Adoption report focus on comparing adoption across groups rather than segments. GitLab 14.0 removes all references to **Segments** [from the GraphQL API](https://gitlab.com/gitlab-org/gitlab/-/issues/324414) and replaces them with **Enabled groups**.
 
 ### Service Templates removed

 Service Templates are [removed in GitLab 14.0](https://gitlab.com/groups/gitlab-org/-/epics/5672). They were used to apply identical settings to a large number of projects, but they only did so at the time of project creation.
 
 While they solved part of the problem, _updating_ those values later proved to be a major pain point. [Project Integration Management](https://docs.gitlab.com/ee/user/admin_area/settings/project_integration_management.html) solves this problem by enabling you to create settings at the Group or Instance level, and projects within that namespace inheriting those settings.
 
 ### Sidekiq queue selector options no longer accept the 'experimental' prefix

 GitLab supports a [queue selector](https://docs.gitlab.com/ee/administration/operations/extra_sidekiq_processes.html#queue-selector) to run only a subset of background jobs for a given process. When it was introduced, this option had an 'experimental' prefix (`experimental_queue_selector` in Omnibus, `experimentalQueueSelector` in Helm charts).
 
 As announced in the [13.6 release post](https://about.gitlab.com/releases/2020/11/22/gitlab-13-6-released/#sidekiq-cluster-queue-selector-configuration-option-has-been-renamed), the 'experimental' prefix is no longer supported. Instead, `queue_selector` for Omnibus and `queueSelector` in Helm charts should be used.

 Ubuntu 16.04 [reached end-of-life in April 2021](https://ubuntu.com/about/release-cycle), and no longer receives maintenance updates. We strongly recommend users to upgrade to a newer release, such as 20.04.
 
 GitLab 13.12 will be the last release with Ubuntu 16.04 support.

 [Support for Unicorn](https://gitlab.com/gitlab-org/omnibus-gitlab/-/issues/6078) has been removed in GitLab 14.0 in favor of Puma. [Puma has a multi-threaded architecture](https://docs.gitlab.com/ee/administration/operations/puma.html) which uses less memory than a multi-process application server like Unicorn. On GitLab.com, we saw a 40% reduction in memory consumption by using Puma.
 
 ### Update Auto Deploy template version
 
+WARNING:
+This feature was changed or removed in 14.0

+Before updating GitLab, review the details carefully to determine if you need to make any

+
 In GitLab 14.0, we will update the [Auto Deploy](https://docs.gitlab.com/ee/topics/autodevops/stages.html#auto-deploy) CI template to the latest version. This includes new features, bug fixes, and performance improvements with a dependency on the v2 [auto-deploy-image](https://gitlab.com/gitlab-org/cluster-integration/auto-deploy-image). Auto Deploy CI tempalte v1 will is deprecated going forward.
 
 Since the v1 and v2 versions are not backward-compatible, your project might encounter an unexpected failure if you already have a deployed application. Follow the [upgrade guide](https://docs.gitlab.com/ee/topics/autodevops/upgrading_auto_deploy_dependencies.html#upgrade-guide) to upgrade your environments. You can also start using the latest template today by following the [early adoption guide](https://docs.gitlab.com/ee/topics/autodevops/upgrading_auto_deploy_dependencies.html#early-adopters).

+
 Our CI/CD templates have been updated to no longer use hard-coded references to a `master` branch. In 14.0, they all use a variable that points to your project's configured default branch instead. If your CI/CD pipeline relies on our built-in templates, verify that this change works with your current configuration. For example, if you have a `master` branch and a different default branch, the updates to the templates may cause changes to your pipeline behavior.

 The WIP (work in progress) status for merge requests signaled to reviewers that the merge request in question wasn't ready to merge. We've renamed the WIP feature to **Draft**, a more inclusive and self-explanatory term. **Draft** clearly communicates the merge request in question isn't ready for review, and makes no assumptions about the progress being made toward it. **Draft** also reduces the cognitive load for new users, non-English speakers, and anyone unfamiliar with the WIP acronym.
 
 ### Web Application Firewall (WAF)

+
 The Web Application Firewall (WAF) was deprecated in GitLab 13.6 and is removed from GitLab 14.0. The WAF had limitations inherent in the architectural design that made it difficult to meet the requirements traditionally expected of a WAF. By removing the WAF, GitLab is able to focus on improving other areas in the product where more value can be provided to users. Users who currently rely on the WAF can continue to use the free and open source [ModSecurity](https://github.com/SpiderLabs/ModSecurity) project, which is independent from GitLab. Additional details are available in the [deprecation issue](https://gitlab.com/gitlab-org/gitlab/-/issues/271276).
