# Resource iteration events API **(STARTER)**

> - [Introduced](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/40850) in [GitLab Starter](https://about.gitlab.com/pricing/) 13.4
> - It's [deployed behind a feature flag](../user/feature_flags.md), enabled by default.
> - It's enabled on GitLab.com.
> - It's recommended for production use.
> - For GitLab self-managed instances, GitLab administrators can opt to [disable it](#enable-or-disable-iterations-events-tracking).

NOTE: **Note:**
This feature might not be available to you. Check the **version history** note above for details.

Resource iteration events keep track of what happens to GitLab [issues](../user/project/issues/).

Use them to track which iteration was set, who did it, and when it happened.

### Enable or disable iterations events tracking **(STARTER)**

Iterations events tracking is under development but ready for production use.
It is deployed behind a feature flag that is **enabled by default**.
[GitLab administrators with access to the GitLab Rails console](../administration/feature_flags.md)
can opt to disable it.

To enable it:

```ruby
Feature.enable(:track_iteration_change_events)
```

To disable it:

```ruby
Feature.disable(:track_iteration_change_events)
```
