This PR was opened by the Changesets release GitHub action. When you're ready to do a release, you can merge this and the packages will be published to npm automatically. If you're not ready to do a release yet, that's fine, whenever you add more changesets to main, this PR will be updated.

Releases

@livekit/protocol@1.51.0

Minor Changes

• egress v2: add passthrough to the encoding oneof on StartEgressRequest and ExportReplayRequest; remove the unused EgressHandler.UpdateEgress RPC and the livekit.UpdateEgressRequest message - #1716 (@frostbyte73)

• add RoomEndReason enum and report it on room-ended telemetry: AnalyticsEvent.room_end_reason and WebhookEvent.room_end_reason now say why a room ended (ROOM_END_API_DELETE, ROOM_END_IDLE_TIMEOUT, ROOM_END_SERVER_SHUTDOWN, ROOM_END_SUPERSEDED, ROOM_END_OPEN_FAILED), so room-end volume can be broken down by cause the way participant disconnects already are - #1748 (@paulwe)

• TransferSIPParticipant now returns TransferSIPParticipantResponse instead of google.protobuf.Empty, carrying the transfer id, status, a new SIPTransferReason and the SIP status when the outcome came from a SIP response. SIPTransferInfo gains the same reason. This changes the generated method signature: a transfer that reports a non-successful status without an error means the transfer did not complete. - #1730 (@genseric-ghiro)

• Moved egress passthrough option to an encoding preset. - #1718 (@frostbyte73)

Patch Changes

• Add agent_job_started / agent_job_ended webhook events and a job field on WebhookEvent - #1711 (@erikhortsch)

• agent simulation: add conciseness and conversation_progression to SimulationRun.RunMetrics - #1742 (@u9g)

• Add background_noise, low_quality_microphone, and packet_loss to SimulationRun.Create.Request, so an audio simulation run can impair the simulated user's audio. - #1723 (@u9g)

• Add to_user_override to CreateSIPParticipantRequest to override the user part of the To header, and warn when To/Via are set in the SIP headers map. - #1717 (@genseric-ghiro)

• Remove extraneous format specifier from log string. - #1682 (@alexfish8)

• Move the config observer into utils/configutil and drop the stuttering Config prefix. utils.ConfigObserver, utils.ConfigBuilder, utils.ConfigDefaulter and utils.NewConfigObserver remain as aliases. - #1712 (@paulwe)

• Add data track subscription to sync state - #1703 (@boks1971)

Patch Changes

• Add agent_job_started / agent_job_ended webhook events and a job field on WebhookEvent - #1711 (@erikhortsch)

• utils/list: mutations involving a node the list does not own — removing or moving an unlinked node, inserting an already-linked node, or inserting relative to an unlinked mark — are now no-ops, as in container/list. Previously an unlinked node's zeroed hook made Remove/MoveToFront/MoveToBack clear the list's head and tail, silently stranding every remaining element, and re-inserting a linked node forked the list. - #1753 (@paulwe)

• utils.Promise gains Then(func(T, error)), registering a callback to run when the promise resolves. Callbacks run on the goroutine that calls Resolve, in registration order; registering on an already-resolved promise runs the callback inline on the caller. NewPromise no longer allocates the done channel up front — Done() already created it lazily. - #1747 (@paulwe)

• Add an error_code label to the livekit_psrpc_error_total metric. - #1699 (@paulwe)

• Add realtime (speech-to-speech) reporter methods to gatewayobs, regenerated from cloud-observability schema/gateway.yaml realtime billing columns (split participant and room services #502). - #1663 (@russellmartin-livekit)

• agent simulation: add conciseness and conversation_progression to SimulationRun.RunMetrics - #1742 (@u9g)

• Add background_noise, low_quality_microphone, and packet_loss to SimulationRun.Create.Request, so an audio simulation run can impair the simulated user's audio. - #1723 (@u9g)

• Add to_user_override to CreateSIPParticipantRequest to override the user part of the To header, and warn when To/Via are set in the SIP headers map. - #1717 (@genseric-ghiro)

• Move the config observer into utils/configutil and drop the stuttering Config prefix. utils.ConfigObserver, utils.ConfigBuilder, utils.ConfigDefaulter and utils.NewConfigObserver remain as aliases. - #1712 (@paulwe)

• Track holder goroutines of stuck locks (all RWMutex readers up to 8) and resolve their current stacks - #1701 (@erikhortsch)

• Add data track subscription to sync state - #1703 (@boks1971)
