Changelog

​

[2.1.0] - 2026.09.08

​

Added

• MeetingKit adds virtual background: installVirtualBackground:, uninstallVirtualBackground, enabledVirtualBackground:, setVirtualBackgroundBlur:, setVirtualBackgroundImage:, setVirtualBackgroundInferenceInterval:, setVirtualBackgroundMaskSync:, and isVirtualBackgroundEnabled. It performs person segmentation and then blurs or replaces the background, and installing it doesn’t require a license key.
• Virtual background applies to the single shared camera capture pipeline in the process. It’s a device-level setting that applies to all rooms at once. After a camera switch during the meeting or a reconnect, the SDK automatically re-applies the current configuration, so your app doesn’t need to do it. For usage, see Virtual background.
• SEADeviceType adds SEADeviceTypeHarmonyOS (8) to identify HarmonyOS members.

​

Changed

• The minimum OS requirement is raised from iOS 10.0 to iOS 16.0.
• The RTCEngineKit dependency is upgraded to 3.1.0, and the podspec’s minimum dependency is raised from >= 3.0.0 to >= 3.1.0. The virtual background inference engine onnxruntime-c is pulled in transitively through the RTCEngineKit podspec, so you don’t need to declare it explicitly in your Podfile.

​

Fixed

• Picks up the local preview fix in RTCEngineKit 3.1.0: with virtual background on, the local preview now shows the processed video, matching what the other side sees. Previously the local side could only see the raw camera video.
• Picks up the fix in RTCEngineKit 3.1.0 for video freezing caused by the pre-processing output buffer being released too early and the display buffer conflicting with writes of the next frame.

​

[2.0.2] - 2026.08.28

​

Changed

• The RTCEngineKit dependency is upgraded to 3.0.2, picking up a fix for parsing media streaming service responses.

​

Fixed

• Fixed a crash caused by an underlying parsing error when the media streaming service response no longer returns the upload field.

​

[2.0.1] - 2026.08.14

​

Changed

• The RTCEngineKit dependency is upgraded to 3.0.1, picking up a screen sharing fix.

​

Fixed

• Fixed screen sharing failing to publish in 2.0.0: after the system screen recording started, the extension failed to connect and the system showed “尝试开始无效的直播会话” (“Attempted to start an invalid broadcast session”).
• Fixed -[MeetingKitRoom stopScreenRecord] only canceling publishing without actually ending the system screen recording.

​

[2.0.0] - 2026.08.12

​

Added

• Added the meeting room instance class MeetingKitRoom, which carries all in-meeting capabilities: entering and exiting rooms, local audio, video, and sharing, chat and raise hand, host management, cloud recording, the waiting room, sub-meetings, sign-in, and room data queries.
• Added the room event protocol MeetingKitRoomDelegate, which carries all in-room events.
• MeetingKit adds createRoomWithDelegate: and getRooms to create room instances and query the rooms you have entered.
• MeetingKitRoom adds publishLocalVideo: and enabledSendAudio: to control publishing of local video and audio per room.
• MeetingKitRoomDelegate adds the meetingRoom:onUserUpdate: callback for updates to your own data and the meetingRoom:onReceiveCustomMessage:action:userId:sessionId:nickname: callback for room custom messages.

​

Changed

• MeetingKit is narrowed down to a global singleton that keeps only login and logout, IM, meeting queries and scheduling, device lists, local capture preview, audio routing, and screen capture process integration.
• enterRoom:onSuccess:onFailed:, exitRoom:, callUser:onSuccess:onFailed:, requestOpenCamera:view:onSuccess:onFailed:, requestShare:onSuccess:onFailed:, sendRoomChatMessage:messageType:targetId:onSuccess:onFailed:, switchSpeaker:, enabledAudioModule:, startRemoteView:streamType:view:, the adminXxx family, and the cloud recording, waiting room, sub-meeting, sign-in, room data query, and media configuration APIs move from MeetingKit to MeetingKitRoom.
• MeetingKitDelegate keeps only two global events: onAudioRouteChange:previousRoute: and onApplicationPerformance:cpuUsage:.
• The other in-meeting callbacks move to MeetingKitRoomDelegate and all carry the source room instance as the first parameter. For example, onEnterRoom:userId: becomes meetingRoom:onEnterRoom:userId:, onUserMicStateChanged:micState:reason: becomes meetingRoom:onUserMicStateChanged:micState:reason:, and onReconnecting becomes meetingRoomOnReconnecting:.
• The RTCEngineKit dependency is upgraded to 3.0.0, and the podspec’s minimum dependency is raised from >= 2.5.0 to >= 3.0.0.

​

Improved

• The same account can create multiple room instances at once and enter multiple rooms. Each room’s media and business state is independent, and member data for the same userId across rooms is isolated per room.
• Camera capture and preview, audio routing, and screen capture are managed centrally by MeetingKit as shared device capabilities; whether they are pushed to a given room is controlled separately by that room instance.
• logout exits and destroys all room instances before releasing resources, so your app doesn’t need to exit each room one by one.

​

[1.3.7] - 2026.08.05

​

Changed

Changed

• switchSpeaker: controls only remote audio playback; use switchAudioRoute: to switch the audio output device.
• currentAudioRoute and onAudioRouteChange:previousRoute: reflect the actual system route.
