  • This is for public notes only. Remove the BWE viewer as that is an internal tool.
  • Also remove the ABR strategy feature flags item
  • Also remove the Sequenced cascading item (will be deployed as a larger feature together with backend)
  • Update the RTMP one to mention RTMP restream
  • For the ABR one lets word it better for a customer. It makes the ABR more resilient to high RTT variation on a link nso it doesn switch down layers unnecessarily
  • pingInterval is internal only remove
  • viewer-count leak, need a better view of the outcome for the customer. A viewr count leak doesnt make it clear the impact to the customer.
  • Remove semantic-pull-request change it is internal
  • Remove rts-cli it is internal

Addressed in e454b14: removed the internal-only items and rewrote the remaining fixes around customer impact, including RTMP re-stream reliability, high-RTT ABR resilience, and regional playback recovery.

- Improved RTMP re-stream reliability by handling output back-pressure to prevent stream corruption.
- Fixed audio distortion that could occur with loud audio sources during WebRTC playback.
- Improved Adaptive Bitrate (ABR) resilience on links with high RTT variation, preventing unnecessary switches to lower-quality layers.
- Fixed an issue where abnormal viewer disconnections could prevent new viewers in a region from receiving media.

add one more customer reported bug fix: fixed a recording issue where simulcast WebRTC may lost video in recording. Reference is ticket https://opentelly.atlassian.net/browse/OPTI-3471, but don't show this detail in the release note.
