Release 4.2.0

4.2.0 (2026-08-25)

Enhancements

• WebRTC 150: Upgraded the CocoaPods and Swift Package Manager WebRTC dependencies to 150.0.0 (#391).
• Call Report Diagnostics: Expanded call reports with native codec, media-source, transport, selected ICE-pair, gathered-candidate, and ICE lifecycle data; report logs now redact ICE credentials (#385, #389).
• Reliable Call Report Uploads: Added periodic flushing, chunking for oversized reports, and persistent retry for failed uploads.
• Media Recovery: Added inbound-media health monitoring, ICE restart verification, and relay-only fallback for failed direct VPN media paths (#379, #380, #381, #384).

Bug Fixes

• Push Reconnect Voice SDK ID: Prefer the fresh voice_sdk_id supplied in VoIP push metadata when reconnecting, preventing reconnects from using a stale cached ID (#386).
