+sidebar_order: 50
+description: "Learn how to stop Sentry from automatically creating releases from ingested events so you can manage releases yourself."
+---
+
+<Alert level="info">
+
+This feature is currently in early access. To access it, enable the Early Adopter flag in your [organization settings](https://sentry.io/orgredirect/organizations/:orgslug/settings/).
+
+</Alert>
+
+By default, Sentry creates a release the first time it sees a new release identifier in ingested events. If you'd rather manage releases yourself, you can turn this off in **Project Settings > General Settings > Event Settings** by disabling **Enable release auto-creation from telemetry**.
+
+When this setting is disabled:
+
+- Sentry no longer creates releases from ingested events.
+- Events are still ingested as normal. If the release doesn't already exist, the event just won't have an associated release.
+- Events still associate with releases that already exist, so you keep creating releases explicitly, for example using the [Sentry CLI](/cli/releases/).
+
+This is useful when you want release names to match exactly what your deploy pipeline creates and don't want extra releases generated from telemetry.
