them. It can be done by GitLab administrators with access to GitLab Rails
console.
When you disable a feature flag, the feature is hidden from users and all of the functionality is turned off.
For example, data is not recorded and services do not run.
If you used a certain feature and identified a bug, a misbehavior, or an
error, it's very important that you [**provide feedback**](https://gitlab.com/gitlab-org/gitlab/-/issues/new?issue[title]=Docs%20-%20feature%20flag%20feedback%3A%20Feature%20Name&issue[description]=Describe%20the%20problem%20you%27ve%20encountered.%0A%0A%3C!--%20Don%27t%20edit%20below%20this%20line%20--%3E%0A%0A%2Flabel%20~%22docs%5C-comments%22%20) to GitLab as soon
as possible so we can improve or fix it while behind a flag. When you upgrade
GitLab to an earlier version, the feature flag status may change.
WARNING:
Features deployed behind feature flags may not be ready for
production use. However, disabling features behind flags that were deployed
enabled by default may also present a risk. If they're enabled, we recommend
you leave them as-is.
## Risks when enabling features still in development
Features that are disabled by default may change or be removed without notice in a future version of GitLab.
Data corruption, stability degradation, or performance degradation might occur if
you enable a feature that's disabled by default. Problems caused by using a default
disabled feature aren't covered by GitLab support, unless you were directed by GitLab
to enable the feature.
## Risks when disabling released features
In most cases, the feature flag code is removed in a future version of GitLab.
If and when that occurs, from that point onward you can't keep the feature in a disabled state.
