Angular v21 has been released, featuring innovative tools like Signal Forms and the stable Angular MCP Server. Signal Forms is an experimental library utilizing Signals for scalable, reactive forms, enabling developers to create type-safe, schema-based validations effortlessly. The MCP Server enhances AI integration, providing tools for LLMs to utilize Angular’s latest features and streamline application migrations. Notably, Angular Aria introduces accessible headless components for improved UI patterns. Furthermore, the Angular CLI now defaults to Vitest as the primary test runner while still supporting Karma and Jasmine. Importantly, new Angular apps will no longer include zone.js, addressing performance issues in complex applications. In related news, Svelte launched its MCP Server, enhancing developer experience, while Postman acquired Liblab to automate SDK generation for APIs. Lastly, Avalonia extends .NET MAUI to Linux and web browsers, promoting cross-platform support with improved performance, allowing developers to leverage existing MAUI codebases seamlessly.
