LiveKit Server

This version includes a breaking change for SIP service. SIP service now requires sip.admin in the token's permission grant to interact with trunks and dispatch rules; and sip.call to dial out to phone numbers. The latest versions of server SDKs will include the permission grants automatically.

In this release, we are introducing a major update to our connection quality algorithm. The improved algorithm boasts greater accuracy and quicker responsiveness to network conditions, providing users with early notifications about poor network connections.

We have also introduced a new internal transport between signal and RTC nodes for signal messages. Instead of relying on unreliable one-way pubsub messages, you can now opt for an RPC transport using psrpc. Note: Before setting signal_relay.enabled, please ensure every instance in your cluster is running v1.4.0+; otherwise, instances will be unable to communicate with each other.
