Apr 1, 2026

April 2026 monthly summary focusing on security, reliability, and deployment flexibility across Mattermost mobile and Calls plugin. Implemented TLS 1.3-enabled WebSocket on iOS with migration to URLSession, native sendBinary support, message validation, robust error handling, and updated tests. Enhanced the Job Service with environment-variable passthrough for recorder/transcriber containers and TLS CA certificate support, plus refactoring to avoid import cycles. Fixed clock synchronization in the Call Widget using server-time-based timestamps to prevent negative durations and ensure consistent behavior, with added unit tests. Completed cross-repo maintenance including dependency updates and build/test stability improvements (RN network client updates, go.work adjustments, and test coverage enhancements).

December 2025 monthly summary: Delivered a security-focused enhancement for the mattermost-plugin-calls by implementing Secure TURN Credentials Management. The feature sets the default TURN credential expiration to 4 hours and marks TURN/ICE credentials as secret, reducing credential exposure and strengthening access control for real-time communications. This aligns with security best practices and improves the plugin’s resilience and trust for operators and end users. The work enhances credential lifecycle management and supports easier rotation and auditing across the plugin’s connectivity workflow.
