Release Notes for LiveSwitch Server v1.21

1.21.3.60993

Release date: October 21, 2024

Client SDK

Bug Fixes
  • [LS1-2358] [Web] Resolved intermittent WebSocket signaling disconnections on macOS Sequoia (15.0, 15.0.1) that caused unexpected client unregistration. Implemented client-side keep-alive mechanisms and increased Gateway signaling timeout to 15 seconds to prevent "604::Client does not exist" errors and unwanted connection drops. Applications using affected macOS versions should upgrade to ensure stable WebSocket connectivity.

  • [LS1-2035] [Media-over-WebSockets] Fixed a client bug such that now it only displays frames at the rate they are being sent rather than updating it at a fixed 30 fps.
  • [LS1-2034] [Media-over-WebSockets] Updated client to support dynamically changing the bitrate during a session.

Media Server

Improvements
