Jul 1, 2025July 2025 monthly summary for NordSecurity/nordvpn-linux focusing on delivering user-facing OS accuracy, richer analytics, and more reliable settings tests. Key work included: switching OS version retrieval to a D-Bus-based approach for more accurate, user-friendly OS strings (benefiting Snap packaging) with telemetry updated accordingly; adding architecture metrics to analytics by refactoring initialization to accept a BuildTarget struct that encapsulates version, environment, and architecture details for richer reports; and hardening settings handling and test reliability by refining test parsers, adding an environment variable to disable the TUI loader during automated tests, and improving parsing of allowlisted ports by introducing a Protocol enum constructor and supporting multi-line parameters, with corresponding CI script updates.
