Released: 2026-06-24 Updated: 2026-07-01 [Visit Changelog](https://developers.zoom.us/changelog/video-sdk/android/2.6.0) Summary: Breaking changes include updated audio configuration API naming for consistency, and modifications to external video source handling with new I420Limited and I420Full color range support. Adds a pre-connection flow to accelerate session joins, machine-answer detection for PSTN call-outs, and comprehensive audio QoS statistics. Additional improvements include user failover status tracking, expanded command channel payload limits (now 1024 bytes), and new callbacks for subsession status changes that trigger when users join or leave subsessions. ## Breaking Changes - Support the I420Limited and I420Full color ranges for the external video source. - Rename several audio configuration APIs for naming consistency. - Joining or leaving a subsession now triggers the `onSubSessionStatusChanged` and `onSessionLeave` callbacks in `ZoomVideoSDKDelegate`. ## Added - Add machine-answer detection for PSTN call-out, so the host can tell whether a call was answered by a person or forwarded to voicemail. - Add a pre-connection (two-step join) flow to speed up the actual session join. - Provide audio QoS statistics data. - Support user failover status change. ## Changed - Increase the command channel payload size limit to 1024.
