General#

Added#

• ESM support.

Breaking Changes#

• Migrated from webpack to Vite 8; UMD is now supported via ESM wrapping.
  • This migration to Vite and ESM-by-default introduces breaking changes for existing users.
  • The UMD bundle has been renamed: zoomus-websdk.umd.min.js is now split into client-view.umd.min.js and component-view.umd.min.js. Update your build configuration accordingly to resolve CI errors.
  • The default entry point is now ESM.
  • package.json now declares the following peerDependencies, which must be installed manually: react, react-dom, redux, react-redux, redux-thunk, and lodash. Make sure to state the version requirements.

Enhanced#

• Improved WebRTC connection recovery and failover on weak networks.
• Improved WebCodecs fallback to prevent incorrect fallback, false stalls, and out-of-order frames.
• Improved audio device selection accuracy on mobile.
• Support for WebRTC video on Firefox, Island Browser, and Chrome on Linux.
• Support for audio denoising across a wider range of devices and browser environments.

Client view#

Breaking Changes#

• Migration webpack to vite 8 and support UMD by wrap ESM.

Enhanced#

• Updated PEPC usermedia handling for browser compatibility.
• Optimized the overall Zoom AI workflow.
• Footer layout optimization.
• Adjusted the position of the mobile "Leave" button.
• Draggable annotation button.
• Webinar add onUserAdd, onUserJoin, and onUserLeft API support.
• Host Tools UI changes.
• Enhanced all dialog to support dark theme.
• Reaction settings: restrict to hosts, panelists, or allow all.
• Support for mixed messages sent by native client.
• Update Participants user experience.

Fixed#

• Duplicate meeting.participant_jbh_waiting_left events generated by web users on leave.
• Copy URL includes passcode when "Embed passcode in invite link" toggle is OFF.

Component view#

Fixed#

• Default view: without defaultViewType, the default view in non-SAB environments is Gallery again.
• Resizing during a share: the resize handle resizes the whole view and the share area, and the video container keeps its width. The share divider still changes the video container width.
• Popups: when there is not enough room, popups overlap the video view instead of rendering off-screen.
• DOM change: the share view element changed from canvas[aria-label="Screen share"] to video-player-container > div > video-player[aria-label="Screen share"].Custom CSS that targets canvas needs updating.
• Webinar Q&A button hidden when only isSupportNewQA is set, or host or panelist is in Ribbon view.
