npx @buildinternet/releases get livekit-client-sdk-jsfix: add code 1000 to onclose handler in WebSocketStream - #2086 (@phaitonican)
fix: don't reset mid track map on publisher answers with empty map - #2089 (@lukasIO)
Support simulcast for svc codecs (vp9/av1) - #2083 (@cnderrauber)
Fix the subscriber silently buffering remote ICE candidates after a reconnect - #2054 (@xianshijing-lk)
triggerIceRestart put the subscriber into restartingIce on every reconnect, but only
setRemoteDescription clears that — and the server re-offers the subscriber only when the
reconnect moved the participant to a different node. After an ordinary signal-only resume no
offer arrives, so the flag stayed set for the lifetime of the transport and every subsequent
remote candidate was queued instead of applied, leaving the subscriber unable to adopt any new
network path the server proposed. The subscriber no longer enters that state: the server does
not send candidates ahead of the offer that introduces them, so queueing them gains nothing.
fix: ensure buffered events are flushed on signal reconnection - #2044 (@lukasIO)
fix: error on datastreams when chunks are missing - #2073 (@lukasIO)
Forward DisconnectReason to the ParticipantDisconnected event - #2055 (@seonghunYang)
fix: enqueue signal requests until queue has been drained - #2061 (@lukasIO)
Add roomOptions.dataStream.maxPayloadByteLength to control max data stream size - #2060 (@1egoman)
Fix supportsAdaptiveStream always returning true by comparing typeof against the 'undefined' string. It now returns false in environments without ResizeObserver or IntersectionObserver. - #2059 (@mrpmohiburrahman)
Treat TokenSource JWTs without exp as expired, and still honor exp when nbf is absent - #2057 (@SashaMIT)
Convert internal exports to be external in examples/demo - #2067 (@1egoman)
Decode text data streams without TextDecoder fatal mode for broader runtime support - #2037 (@JoelTowell)
fix: ensure buffered events are flushed on signal reconnection - #2043 (@lukasIO)
fix: cancel pending onTrack callbacks when subscription fails - #2019 (@lukasIO)
fix: match opus fmtp parameters by exact token and look up the opus codec case-insensitively when munging SDP - #2036 (@lukasIO)
Only run the TrackEvent.TimeSyncUpdate animation frame loop while something is subscribed to the event, and clear the frame handle when a track's monitor is stopped so the loop can be restarted - #2038 (@U-OK)
fix: emit TrackStreamStateChanged again by reading the previous stream state before overwriting it - #2039 (@tomkail)
Apply the resolved degradation preference to the backup codec's sender - #2040 (@xianshijing-lk)
Degradation preference is a property of the sender, not of the track, and a backup codec publishes over its own sender. Previously only the primary sender was configured, so the backup encoder resolved a preference implicitly and could adapt along a different axis than the primary.
fix: recover broken publish paths — act on local ConnectionQuality.Lost, recreate the peer connection when an ICE restart has no remote description, bound how long a transport may stay connecting, and reconnect (instead of disconnecting) on a detected connection state mismatch - #2030 (@lukasIO)
fix: enable Terser mangle.safari10 to fix scoping issues for variables in react-native - #2028 (@davidliu)
fix: ensure dd extension also for recvonly - #2052 (@lukasIO)
fix: emit events that were buffered during resume after declaring the room as reconnected - #2018 (@lukasIO)
Ensure empty error reasons use fallback notation - #1999 (@lukasIO)
Remove stale data track subscriber handles from the packet routing table - #2011 (@ladvoc)
Fix the reliable data channel dying under concurrent / multi-packet writes (#1995). Data-channel sends now use two-watermark flow control (fill up to a high-water mark, resume when drained to a low-water mark) and serialize contended senders through a per-kind lock, which prevents the SCTP send buffer from overflowing while keeping throughput saturated for data tracks. - #2013 (@1egoman)
Keep attached audio elements muted in startAudio() when webAudioMix is enabled, preventing double playback on platforms where element.volume has no effect (e.g. iOS Safari) - #2004 (@sawa-zen)
Add a localAudioTrack.applyConstraints method with a subset of AudioCaptureOptions - #2001 (@lukasIO)
Conform placeholder sections to the canonical fmtp for each shared payload - #1993 (@lukasIO)
Include the NonSharedUint8Array type polyfill in the published declarations. - #1997 (@1egoman)
The type was declared in an ambient .d.ts that was resolved during our own
build but never emitted to dist, so the published .d.ts files referenced a
type consumers could not resolve — surfacing as Cannot find name 'NonSharedUint8Array' under skipLibCheck: false and as Unable to follow symbol for "NonSharedUint8Array" in API Extractor (which broke downstream
packages such as @livekit/components-*). The polyfill is now an exported type
that is imported explicitly wherever it is used, so it ships in dist and the
published types type-check standalone.

Disable publisher offer with join in firefox - #1954 (@cnderrauber)
Fix memory leak where the constructor-registered devicechange listener on navigator.mediaDevices was not removed when a Room was constructed but never connected. The listener kept the Room instance reachable from the global navigator.mediaDevices EventTarget, defeating the FinalizationRegistry cleanup. - #1944 (@nikhilgupta58)
