Angular 9.1 has arrived, with improvements for performance and concurrency to the ngcc compatibility compiler. The Ivy compilation and rendering pipeline received attention as well, resulting in better performance.

Angular 9.1, published March 25, follows the Angular 9.0 release, which became available as a production release on February 6, 2020. The version 9.0 upgrade to the popular TypeScript-based framework switches applications to the Ivy compiler and runtime by default.

Ivy offers faster, AOT compilation as well as smaller bundle sizes, faster testing, and better debugging. Improved CSS class and style binding is featured in Ivy as well, along with improvements in type checking, build errors, and build times. Also part of Angular 9 is ng update, which promises to be a more reliable and informative tool for updating applications and their dependencies.
