The Task Runner pod is used to execute periodic housekeeping tasks within the GitLab application and is often confused with the GitLab Runner. Thus, [Task Runner will be renamed to Toolbox](https://gitlab.com/groups/gitlab-org/charts/-/epics/25).
This will result in the rename of the sub-chart: `gitlab/task-runner` to `gitlab/toolbox`. Resulting pods will be named along the lines of `{{ .Release.Name }}-toolbox`, which will often be `gitlab-toolbox`. They will be locatable with the label `app=toolbox`.
### Release CLI be distributed as a generic package
The [release-cli](https://gitlab.com/gitlab-org/release-cli) will be released as a [generic package](https://gitlab.com/gitlab-org/release-cli/-/packages) starting in GitLab 14.2. We will continue to deploy it as a binary to S3 until GitLab 14.5 and stop distributing it in S3 in GitLab 14.6.
Audit events for [repository events](https://docs.gitlab.com/ee/administration/audit_events.html#repository-push) are now deprecated and will be removed in GitLab 15.0.
As part of the work to create a [Package Registry GraphQL API](https://gitlab.com/groups/gitlab-org/-/epics/6318), the Package group deprecated the `Version` type for the basic `PackageType` type and moved it to [`PackageDetailsType`](https://docs.gitlab.com/ee/api/graphql/reference/index.html#packagedetailstype).
In milestone 15.0, we will completely remove `Version` from `PackageType`.
[GitLab Serverless](https://docs.gitlab.com/ee/user/project/clusters/serverless/) is a feature set to support Knative-based serverless development with automatic deployments and monitoring.
We decided to remove the GitLab Serverless features as they never really resonated with our users. Besides, given the continuous development of Kubernetes and Knative, our current implementations do not even work with recent versions.
### Known host required for GitLab Runner SSH executor
In [GitLab 14.3](https://gitlab.com/gitlab-org/gitlab-runner/-/merge_requests/3074), we added a configuration setting in the GitLab Runner `config.toml` file. This setting, [`[runners.ssh.disable_strict_host_key_checking]`](https://docs.gitlab.com/runner/executors/ssh.html#security), controls whether or not to use strict host key checking with the SSH executor.
In GitLab 15.0 and later, the default value for this configuration option will change from `true` to `false`. This means that strict host key checking will be enforced when using the GitLab Runner SSH executor.
The syntax of [GitLabs database](https://docs.gitlab.com/omnibus/settings/database.html)
configuration located in `database.yml` is changing and the legacy format is deprecated. The legacy format
supported using a single PostgreSQL adapter, whereas the new format is changing to support multiple databases. The `main:` database needs to be defined as a first configuration item.
This deprecation mainly impacts users compiling GitLab from source because Omnibus will handle this configuration automatically.
This gem has not been maintained and has very little usage. We therefore plan to remove support for this authentication method and recommend using the Kerberos [SPNEGO](https://en.wikipedia.org/wiki/SPNEGO) integration instead. You can follow the [upgrade instructions](https://docs.gitlab.com/ee/integration/kerberos.html#upgrading-from-password-based-to-ticket-based-kerberos-sign-ins) to upgrade from the `omniauth-kerberos` integration to the supported one.
Note that we are not deprecating the Kerberos SPNEGO integration, only the old password-based Kerberos integration.
### Remove the `:dependency_proxy_for_private_groups` feature flag
We added a feature flag because [GitLab-#11582](https://gitlab.com/gitlab-org/gitlab/-/issues/11582) changed how public groups use the Dependency Proxy. Prior to this change, you could use the Dependency Proxy without authentication. The change requires authentication to use the Dependency Proxy.
In milestone 15.0, we will remove the feature flag entirely. Moving forward, you must authenticate when using the Dependency Proxy.
### `AuthenticationType` for `[runners.cache.s3]` must be explicitly assigned
In GitLab 15.0 and later, to access the AWS S3 cache, you must specify the `AuthenticationType` for [`[runners.cache.s3]`](https://docs.gitlab.com/runner/configuration/advanced-configuration.html#the-runnerscaches3-section). The `AuthenticationType` must be `IAM` or `credentials`.
Prior to 14.5, if you did not define the `AuthenticationType`, GitLab Runner chose a type for you.
With the general availability of Gitaly Cluster ([introduced in GitLab 13.0](https://about.gitlab.com/releases/2020/05/22/gitlab-13-0-released/)), we have deprecated development (bugfixes, performance improvements, etc) for NFS for Git repository storage in GitLab 14.0. We will continue to provide technical support for NFS for Git repositories throughout 14.x, but we will remove all support for NFS in GitLab 15.0. Please see our official [Statement of Support](https://about.gitlab.com/support/statement-of-support.html#gitaly-and-nfs) for further information.
We encourage customers currently using NFS for Git repositories to plan their migration by reviewing our documentation on [migrating to Gitaly Cluster](https://docs.gitlab.com/ee/administration/gitaly/index.html#migrate-to-gitaly-cluster).
