 # Changelog
 
+## 2026-04-01 - 3.49.1 - fix(ts_web)
+resolve TypeScript nullability and event typing issues across web components
+
+- adds explicit non-null assertions and nullable types to component properties, shadowRoot queries, and modal references
+- normalizes demo and component event listeners by casting generic Event objects to CustomEvent where needed
+- guards optional form, dropdown, menu, and DOM interactions to prevent invalid access under stricter TypeScript checks
+- updates tsconfig to include Node types for the web build environment
+
 ## 2026-03-18 - 3.49.0 - feat(dataview-statusobject)
 add last updated footer to status object and refresh demo data
