    🚀 New Features

    • • Time-sensitive notifications - Added ability for users to join live AI assistant calls when they miss the initial invite
    • • Enhanced call details UI - Implemented richer information display for calls, callers, and call analysis
    • • Known caller identification - Added visual indicators to distinguish known callers in call logs and agent calls
    • • Agent call analysis caching - Implemented local storage of AI assistant call analysis to prevent redundant API calls

    🛠️ Improvements

    • • Targeted websocket messaging - Enhanced server to send messages only to relevant client connections based on user ID
    • • Extended ring duration - Increased dial time for unwanted callers from 15 to 20+ seconds using Twilio redirect timeouts
    • • Simplified call notification system - Streamlined incoming call handling by leveraging Twilio's direct notification capabilities
    • • Robust encryption management - Upgraded to actor model for thread-safe key management and data encryption
    • • Call cost calculation - Improved accuracy of cost tracking after call completion
    • • Push notification reliability - Enhanced device re-registration for notification token updates

    🐛 Fixes

    • • Terminated state crashes - Resolved app crashes during incoming calls due to encryption initialization failures
    • • Conference call guardrails - Prevented users from joining ended live listening spaces
    • • UI state management - Fixed screens failing to update and reset after being triggered
    • • Blank screen handling - Eliminated blank screens when errors occur on chat call screens
    • • Call termination - Ensured all calls can be properly ended from system level, including active Twilio calls
    • • Websocket connection drops - Addressed recurring connection stability issues affecting caller information retrieval

    🧪 Experiments / Beta

    • • SIP connection exploration - Investigated Drachtio, Signalwire, and Telnyx for direct SIP integration (ultimately postponed)
    • • Actor model websocket system - Built new concurrent-safe websocket architecture but decided against migration for now
    • • Concurrent call tracking - Developed solution for monitoring multiple AI assistant calls (postponed for launch focus)
    • • AI Outbound call — Similar to Google Duplex, allow the user to offload mundane call tasks to an AI assistant

    🎯 Next Week Priorities

    • • Renew Apple Developer Account - Critical blocker for TestFlight and App Store releases
    • • Release external TestFlight build - Distribute to broader testing audience once account is restored
    • • Complete App Store submission - Finalize paywall testing through production environment
    • • Create Apple reviewer account - Set up credentials for App Store review process
    • • Address websocket reliability - Continue improving connection stability in terminated states
