Feb 1, 2026February 2026 -- NordVPN Linux: Added automated tests for Encrypted Client Hello (ECH) Remote Configuration. The new autotests validate ECH remote config options, ensuring correct functionality and logging behavior across settings, and were implemented under LVPN-10034 in NordSecurity/nordvpn-linux. This work strengthens release confidence by catching misconfigurations early, improving stability and security posture for Linux deployments. It also lays groundwork for CI coverage of future ECH-related changes.

Aug 1, 2025Month: 2025-08 — NordSecurity/nordvpn-linux: Delivered a robust Remote Configuration (RC) automation testing framework and immediate reliability improvements. Established automated tests for RC initialization, local/remote configuration interactions, and edge scenarios (local file deletion, hash changes, remote disable). Introduced test fixtures, environment detection checks, and tests covering initial RC loading and cross-behavior scenarios. Refactored test suite to improve reliability by leveraging shell utilities and expanded integration coverage across RC initialization and behavior. This work reduces RC-related risk, accelerates feedback, and sets the foundation for ongoing automation expansion within the NordVPN Linux repository.
