# Aug 25, 2026 — MSL5 Production Release

This release introduces enhanced streaming capabilities, expanded data export options, and improved API compatibility to support diverse customer use cases and operational requirements.

# MSL Origin updates

* **HLS Live Stream Retention**: Extended HLS live segment download and scrub back retention from 12 to 24 hours to support longer streaming events with lookback capability.
* **Stream API Backward Compatibility**: Stream API GET/List responses no longer return the legacy `dvr_window_in_min` field, and PUT/POST requests now ignore it in favor of `playlist_duration_in_min`, enabling seamless GET-then-PUT workflows without manual payload modification.
* **Enhanced Ingest Log Export**: Extended Ingest Log Export with additional fields (`request_id`, `body_bytes_sent`, `request_length`).
* **TrafficPeak Integration**: Added support for exporting ingest logs and origin HTTP access logs to TrafficPeak (API only, no Portal UI support yet).

# MSL Portal update

* Fixed **Metrics Report** relative time range filter to correctly update on subsequent Apply actions, ensuring accurate time-based data queries.
