## Available feature flags

The feature flags available to you depend on:

- Whether you use the GitLab Community Edition or GitLab Enterprise Edition [software distribution](https://about.gitlab.com/install/ce-or-ee/).
- The version of GitLab you use.
- Whether the feature is enabled or disabled on your GitLab self-managed instance or GitLab
  SaaS.

The following sections describe the **default** state of each feature flag.

<% feature_flags_yaml[:products].each do |product, ffs| %>
### <%= product %>

<%= ffs.count %> feature flags are available in <%= product %>.

<% sorted_ff = ffs.sort_by { |ff| ff[:name] } %>

| Name | Group  | Milestone | Default state | Rollout issue |
|------|--------|-----------|---------------|---------------|
<% sorted_ff.each do |ff| %>| <%= ff[:introduced_by_url] ? "[`#{ff[:name]}`](#{ff[:introduced_by_url]})" : "`#{ff[:name]}`" %> | `<%= ff[:group] || 'Not defined' %>` | <%= ff[:milestone] || 'Not defined' %> | <%= enabled_state(ff) %> | <%= ff[:rollout_issue_url] ? "<#{ff[:rollout_issue_url]}>" : 'Not defined' %> |
<% end %>

<% end %>

## Ownership by group

GitLab features are developed by
[engineering groups](https://about.gitlab.com/handbook/product/categories/) that implement features
using feature flags.

<% all_ffs = feature_flags_yaml[:products].map { |_, ffs| ffs }.flatten %>
<% ff_groups = all_ffs.group_by { |ff| ff[:group] || 'Not defined' }.sort_by { |group, _| group } %>

| Group | Count | Enabled | Disabled |
|-------|-------|---------|----------|
<% ff_groups.each do |group, ffs| %> | `<%= group %>` | <%= ffs.count %> | <%= enabled_count(ffs) %> | <%= disabled_count(ffs) %> |
<% end %>

## Count by milestone

GitLab features [are delivered](https://about.gitlab.com/handbook/engineering/releases/):

- Continuously for GitLab SaaS.
- On the 22nd of every month according to specific milestones for GitLab self-managed.

<% all_ffs = feature_flags_yaml[:products].map { |_, ffs| ffs }.flatten %>
<% ff_milestones = all_ffs.group_by { |ff| ff[:milestone].to_s || 'Not defined' }.sort_by { |milestone, _| milestone } %>

| Milestone | Count | Enabled | Disabled |
|-----------|-------|---------|----------|
<% ff_milestones.each do |milestone, ffs| %> | <%= milestone %> | <%= ffs.count %> | <%= enabled_count(ffs) %> | <%= disabled_count(ffs) %> |
<% end %>
<% end %>
