 # Changelog
 
+## 2026-03-27 - 3.6.3 - fix(tapbundle_serverside)
+add TapNodeTools cleanup hooks to stop SmartNetwork processes after tests
+
+- replace the exported tapNodeTools singleton with a TapNodeTools class that registers cleanup on the tap instance
+- run registered cleanup functions at the end of tap.start() to prevent lingering background processes from keeping Node.js alive
+- stop SmartNetwork after selecting Chromium runtime ports and update smartnetwork to ^4.5.2
+
 ## 2026-03-27 - 3.6.2 - fix(cli,chromium-runtime)

+### How cleanup works
+
+`TapNodeTools` accepts any object with a `registerCleanup()` method (the `tap` instance). On construction, it registers a cleanup callback that stops long-lived background processes (e.g. the SmartNetwork Rust bridge). When `tap.start()` finishes running all tests, it calls all registered cleanup functions automatically, so the Node.js event loop can drain and the process exits cleanly.
