Angular Hot Reload - Fixed critical issue where Angular projects would crash after 2-3 code edits with "Maximum call stack size exceeded" or "JIT compiler not available" errors. The fix: upgraded to Angular 21 with zoneless mode. No more zone.js, cleaner hot reload, smaller bundles, and better performance.
Improvements
Angular 21.0.2 - Updated from Angular 17 to the latest Angular 21 with modern features and improved performance.
Zoneless Change Detection - Angular template now uses provideZonelessChangeDetection() for cleaner architecture without zone.js overhead.
