This update focuses on accuracy and reliability, making test results more trustworthy across the board. Improvements - Connection ramp-up now matches your configured rate exactly, even when the test spans multiple worker processes - Tests now complete reliably when the broker drops established connections mid-test — exactly the scenario a load tester is for - Real-time connection events (history and first-failure detection) are reported reliably again - Client IDs now follow the documented prefix-worker-connection format shown in the app - Broker passwords in saved presets are now stored securely in the Keychain - Configuration is validated before starting, with clear error messages instead of silent failures - Number fields can now be cleared and retyped freely Fixes - Fixed a hang on "Spawning workers…" when a worker process failed to start - Fixed duplicate test runs in distributed client mode caused by repeated start broadcasts - Fixed stale workers receiving connection assignments after reducing the connection count - Fixed metrics briefly flickering between two different sets of numbers during a test - Fixed a potential crash when scanning network interfaces in distributed mode
