Release Notes for LiveSwitch Server v1.13

1.13.1.54330

Release date: August 4, 2021

[LS-6193] Data sent on a webhook configured as Reliable now expires after three attempts instead of retrying forever. Also, Webhook requests attempted with an invalid URL or to a server that returns an SSL certificate error fail immediately instead of retrying.

[IL-3451] Upgraded the Gradle plugin to 4.2.2 and the Gradle version to 7.1 to ensure compatibility with Android Studio 4.2.

[LS-6704] Fixed a bug in the Web SDK where the set value of MaxSendBitrate for an audio or video stream was overwritten by a higher value sent from a remote client or server. MaxSendBitrate will now take whichever value is lower between the remote and local values.
[LS-6719] Fixed a bug where web-based clients were not responding to bitrate requests to suspend media flow. Clients continued sending media when only one client was present on a channel. Under certain conditions, this bug also increased signalling traffic.
[LS-6734] Added a workaround for a bug in Chrome 90, 91, and 92 where video jitter in getStats is reported as 90 times higher than it actually is.
[LS-6958] Fixed a bug in the Web SDK where destroying an instance of LocalMedia or RemoteMedia would not fully clean up the underlying resources in Chrome. This caused an issue in Chrome 92 where after a large number of overall connections, further instances of LocalMedia or RemoteMedia could not be rendered.

[LS-6824] Fixed a bug where Media Servers would send bitrate requests to clients on versions older than 1.13.1 when they were alone in a channel. These clients cannot handle these requests, but the Media Server would continue sending them redundantly. Clients on version 1.13.1 will continue to receive bitrate requests.

[LS-5536] The Custom MCU Layout function now returns an optional crop parameter.
[LS-5838] A new DefaultRegisterExpiry parameter has been added to the SipTrunk data model in the REST API and Gateway configuration to support configuring the default register expiry.
[LS-5795] Added configuration for ICE and TURN port ranges to the Deployment configuration console.
[LS-5938] New Bus Configuration control in the Deployment configuration that allows you to set an AMQP server.
[LS-5922] New External Redirect controls in the Deployment and Application configuration consoles that allow you to configure your own sync and admin URLs.

[LS-5891] Updated the Windows installer to .NET Framework 4.8.
[LS-5940] Started routing TMMBR and TMMBN control messages over internal data streams instead of signalling channels. This allows to decrease the load on Media Server and Gateway signalling, increasing system capacity. If data streams are not requested by the application code, they will be added in the offer. Internal data channels will have a label with an "fm/" prefix. LiveSwitch will not allow public data channel with labels starting with "fm/".
[IL-3426] New content parameter for inputs in custom MCU video layouts. This parameter is set to either camera or screen if the source content is known.
[IL-3426] New videoContent field in recording JSON metadata. This field is set to either camera or screen if the source content is known.
[LS-6026] Improved MCU simulcast efficiency.

[LS-5891] Updated the Windows installer to .NET Framework 4.8.
[LS-5935] New channel.client.message event type for webhooks. This event type is triggered by messages sent to a channel from a client using the Channel API in the client SDK.
[LS-5935] New channel.server.message event type for webhooks. This event type is triggered by messages sent to a channel from the server using the REST API.
[LS-5937] New client.message event type for webhooks. This event type is triggered by messages sent to the server from a client using the Client API in the client SDK.
[LS-5937] New server.message event type for webhooks. This event type is triggered by messages sent to a client from the server using the REST API.
[LS-5937] New REST API endpoint v1/applications/{applicationId}/users/{userId}/devices/{deviceId}/clients/{clientId}/message for sending messages directly to a client outside a channel.
[LS-5937] New REST API endpoint v1/applications/{applicationId}/users/{userId}/devices/{deviceId}/message for sending messages directly to a device outside a channel.
[LS-5937] New REST API endpoint v1/applications/{applicationId}/users/{userId}/message for sending messages directly to a user outside a channel.
[LS-5937] New REST API endpoint v1/applications/{applicationId}/message for sending application-wide messages.

[LS-5891] Updated the Windows installer to .NET Framework 4.8.
[LS-6111] Updated naming conventions for SIP Connector executable and configuration file to match other services.

[LS-5937] New sendMessage method in the Client API. This method can be used to send messages to the server that do not propagate, i.e. go to webhooks only.
[LS-5937] New OnMessage, OnDeviceMessage, OnUserMessage, and OnApplicationMessage events in the Client API for messages sent to the current client, device, user, or application outside a channel.
[IL-3426] New SendContent and ReceiveContent properties in MediaStreamInfo. These properties are set to either camera or screen for video streams if the source contents are known.
[IL-3426] New Content property in MediaSource, MediaPipe, MediaSink, and MediaStream. This property is set to either camera or screen for video pipeline elements if the source content is known.

[LS-5995] Fixed an issue where generateClientRegisterToken would not allow omission of clientRoles as an argument.

[LS-6183] Fixed a bug that prevented recording in a channel from activating after being deactivated using the REST API.

[LS-5933] Fixed an ephemeral Redis leak for channels that were active for extended periods of time and used multiple Media Servers during their lifetime.
[LS-5937] Fixed a bug where client roles could be prefixed with white-space if multiple client roles were provided.
[LS-5937] Fixed a bug where user alias, device alias, tag, roles, external ID, region, and version did not appear in client unregistered and channel join/leave events.

[LS-6207] Fixed a bug causing the SIP Connector to timeout outbound calls after 32 seconds despite receiving a provisional response from the remote server.
[LS-6153] Fixed a bug causing the SIP Connector to timeout calls after 40 seconds for the SIP providers not supporting RTCP multiplexing and with infrequent (or no) RTCP traffic.
