 ## [Unreleased]
 
-### Removing S3 storage-event webhooks for recordings
-
-Recordings were previously confirmed as saved by an S3 storage-event webhook posting to `/api/v1.0/recordings/storage-hook/`. That endpoint has been removed: recordings are now always finalized from LiveKit's own `egress_ended` webhook, which has been the default path since v1.22.0.
-
-**Required for every deployment:** LiveKit must be able to deliver webhooks to the backend at `/api/v1.0/rooms/webhooks-livekit/`. This is now the only way a recording reaches a saved state; if `egress_ended` is never delivered, recordings stay in the `active` state.
-
-For hosters who had configured storage-event webhooks:
-- Recordings reach the same final state, but they are now finalized when LiveKit reports the egress as ended rather than when the storage backend reports the upload.
-- Remove the event notification from your bucket configuration: it now targets a non-existent endpoint and will fail on every delivery.
-
-For hosters who had **not** configured storage-event webhooks:
-- Nothing changes. Recordings have been finalized from the `egress_ended` webhook since v1.22.0.
-
-In both cases, the following settings are no longer used and can be removed from your env: `RECORDING_EVENT_PARSER_CLASS`, `RECORDING_ENABLE_STORAGE_EVENT_AUTH`, `RECORDING_STORAGE_EVENT_ENABLE`, `RECORDING_STORAGE_EVENT_TOKEN`.
-
-On completion of the egress, a recording moves to `notification_succeeded`, or to `saved` if notifying external services failed.
-
 ## v1.23.0
 
 As part of the 1.23.0 release, the legacy `api/v1` implementation has been removed from the _experimental_ Summary service and Meet has been migrated to the new `api/v2`.

+### Manual Storage Webhook
+
+Storage events must be configured manually; the Kubernetes chart does not do this automatically.
+
+1. Configure your S3 bucket to send file creation events to the backend webhook.
+2. Enable events and token in settings:
+
+```python
+RECORDING_STORAGE_EVENT_ENABLE = True
+RECORDING_ENABLE_STORAGE_EVENT_AUTH = True
+RECORDING_STORAGE_EVENT_TOKEN = <token>
+```
