This feature used to be called `stabilityDays`.

If this is set _and_ an update has a release timestamp header, then Renovate will check if the set duration has passed.
If `minimumReleaseAge` is set to a number value _and_ the update has a release timestamp header, then Renovate will check if the set duration has passed.

Note: Renovate will wait for the set duration to pass for each **separate** version.
Renovate does not wait until the package has seen no releases for x time-duration(`minimumReleaseAge`).
`minimumReleaseAge` is not intended to help with slowing down fast releasing project updates.
If you want to slow down PRs for a specific package, setup a custom schedule for that package.
Read [our selective-scheduling help](./noise-reduction.md#selective-scheduling) to learn how to set the schedule.

If the time since the release is less than the set `minimumReleaseAge` a "pending" status check is added to the branch.
If enough days have passed then the "pending" status is removed, and a "passing" status check is added.
Do _not_ use `minimumReleaseAge` to slow down fast releasing project updates.
Instead setup a custom `schedule` for that package, read [our selective-scheduling help](./noise-reduction.md#selective-scheduling) to learn how.

Some datasources don't have a release timestamp, in which case this feature is not compatible.
Other datasources may have a release timestamp, but Renovate does not support it yet, in which case a feature request needs to be implemented.
When the time passed since the release is _less_ than the set `minimumReleaseAge`: Renovate adds a "pending" status check to that update's branch.
After enough days have passed: Renovate replaces the "pending" status with a "passing" status check.

Maven users: you cannot use `minimumReleaseAge` if a Maven source returns unreliable `last-modified` headers.
The datasource that Renovate uses must have a release timestamp for the `minimumReleaseAge` config option to work.
Some datasources may have a release timestamp, but in a format that's Renovate does not support.
In those cases a feature request needs to be implemented.

For `minimumReleaseAge` to work, the Maven source must return reliable `last-modified` headers.

Configuring this option will add a `renovate/stability-days` option to the status checks.

There are a couple of uses for `minimumReleaseAge`:
Examples of how you can use `minimumReleaseAge`:

#### Suppress branch/PR creation for X days

If you combine `minimumReleaseAge=3 days` and `internalChecksFilter="strict"` then Renovate will hold back from creating branches until 3 or more days have elapsed since the version was released.
We recommend that you set `dependencyDashboard=true` so you can see these pending PRs.

#### Prevent holding broken npm packages

npm packages less than 72 hours (3 days) old can be unpublished, which could result in a service impact if you have already updated to it.
npm packages less than 72 hours (3 days) old can be unpublished from the npm registry, which could result in a service impact if you have already updated to it.
Set `minimumReleaseAge` to `3 days` for npm packages to prevent relying on a package that can be removed from the registry:

#### Await X time duration before Automerging

If you enabled `automerge` _and_ `minimumReleaseAge`, it means that PRs will be created immediately but automerging will be delayed until the time-duration has passed.
This works because Renovate will add a "renovate/stability-days" pending status check to each branch/PR and that pending check will prevent the branch going green to automerge.
If you enable `automerge` _and_ `minimumReleaseAge`, Renovate will create PRs immediately, but only automerge them when the `minimumReleaseAge` time-duration has passed.

Renovate adds a "renovate/stability-days" pending status check to each branch/PR.
This pending check prevents the branch going green to automerge before the time has passed.
