LiveSwitch 1.27 Release

Release Notes for Client SDK 1.27

1.27.0.22319

Release date: July 31, 2026

Client SDK

Improvements
  • [LS1-3462] [Web] The example app now displays a remote mute indicator, so participants can see when another participant has muted their microphone.
  • [LS1-3733] [Web] The example app now shows audio and video mute state overlays on video tiles.
Bug Fixes
  • [LS1-2613] [MAUI Android] Fixed an issue in the example app where backgrounding the app during a call caused video to freeze and the connection to reconnect on return. The example now runs the call in a foreground service while the app is in the background. Because Android requires each app to declare its own foreground service and lifecycle handling, this isn't something the SDK applies for you — see the MAUI Chat example for the pattern, or contact support for guidance on applying it to your own app.
  • [LS1-2876] [MAUI Android] Fixed an app crash when accepting the notification prompt while joining in Screen Share Only mode. Joining a Screen Share Only session now works reliably across P2P and SFU connections.
  • [LS1-3472] [Unity iOS] Fixed an issue where call audio played through the earpiece instead of the loudspeaker when joining an SFU call, making calls hard to hear. Audio now routes to the loudspeaker by default.
  • [LS1-3522] [MAUI Android] Fixed the device screen turning off and going to sleep during an active call, which could interrupt video and audio. The screen now stays awake for the duration of a call.
  • [LS1-3523] [MAUI Android] Fixed local self-video freezing after the app returned from the background. The camera now resumes automatically on return to the foreground.
  • [LS1-3670] Fixed an issue where peer-to-peer calls could unnecessarily fall back to TURN relay even when a direct connection between clients was available, resulting in avoidable relay bandwidth usage and added connection latency.
  • [LS1-3678] [Web] Fixed an issue in P2P mode where the answer SDP always contained sendrecv regardless of the joining client's configured direction (receive-only or send-only), causing setRemoteDescription to fail with an InvalidAccessError.
  • [LS1-3694] [.NET] Fixed an issue where the SDK NuGet packages were missing the native OpenSSL library (libopensslfm.dylib) on macOS, causing applications referencing SDK 1.23.0 or later to fail at runtime with a missing native library error.
  • [LS1-3704] Fixed an issue where MCU receive-only clients would see permanently degraded, blocky video after all receivers disconnected and rejoined a session, because the server failed to request a new keyframe from the upstream publisher.
  • [LS1-3705] [Web] Fixed an issue in the example app where muting audio or video after switching from SFU to MCU mode would throw an error instead of updating the connection.
  • [LS1-3706] [Web] Fixed several connection lifecycle issues in the example app, including stale connection references and missing cleanup.
  • [LS1-3723] Fixed an issue where channel update messages could be silently discarded, so OnRemoteClientUpdate never fired for other participants even though the sending client's update() call succeeded.
  • [LS1-3733] Fixed an issue where SFU downstream connections did not reflect the upstream participant's muted audio/video state until the first connection update after connecting.
  • [LS1-3739] [Web] Fixed an issue in the example app where audio and video mute buttons had no effect in P2P mode before any peer had joined the channel.
  • [LS1-3742] Fixed a race condition where calling Update() twice in rapid succession (e.g. muting audio and video within ~100ms of each other) could silently drop one of the state changes.
  • [LS1-3744] Fixed an issue where a connection's reported maximum video resolution could incorrectly reflect the send stream dimensions instead of the larger receive stream dimensions.
  • [LS1-3746] [Unity] Fixed an issue where libopensslfm_stub.c was missing from the package, causing LNK2019 linker errors when building IL2CPP targets.
  • [LS1-3747] [MAUI iOS] Fixed an issue in the example app where backgrounding the app during a call dropped audio and caused the connection to reconnect on return. The example now declares background audio/VoIP modes and pauses/resumes the camera on background/foreground transitions. As with the Android fix above, this is an application-level change you'll need to replicate yourself — see the MAUI Chat example for the pattern, or contact support for guidance on applying it to your own app.
