+- [ONCEHUB-112987](https://scheduleonce.atlassian.net/browse/ONCEHUB-112987) Upgrade to Angular 21 and Node 24
+  - **BREAKING**: Upgraded Angular packages to v21.1.x
+  - **BREAKING**: Minimum Node.js version is now 24 (updated CI to Node 24.13.0)
+  - **BREAKING**: Migrated ESLint configuration to flat config format (ESLint v9) with `angular-eslint` v21.3.0, replacing the legacy `.eslintrc`-based setup
+  - Removed individual `@angular-eslint/*`, `@typescript-eslint/*`, `eslint-plugin-import`, `eslint-plugin-jsdoc`, and `eslint-plugin-prefer-arrow` packages in favour of the unified `angular-eslint` package
+  - Updated `tslib` to `^2.8.1`
+
 ## [5.1.6] - 2026-01-15
