Version 10.0.0 is here! This is a major release that spans the entire platform, including the framework, Angular Material, and the CLI. This release is smaller than typical; it has only been 4 months since we released version 9.0 of Angular.

We try to release two major versions each year to keep Angular synchronized with the rest of the JavaScript ecosystem and to have a predictable schedule. We plan to release version 11 this fall.

What’s in this release?

New Date Range Picker

Angular Material now includes a new date range picker.

To use the new date range picker, you can use the mat-date-range-input and mat-date-range-picker components.

See this example on StackBlitz.

Warnings about CommonJS imports

When you use a dependency that is packaged with CommonJS, it can result in larger slower applications.

Starting with version 10, we now warn you when your build pulls in one of these bundles. If you’ve started seeing these warnings for your dependencies, let your dependency know that you’d prefer an ECMAScript module (ESM) bundle.

CommonJS or AMD dependencies can cause optimization bailouts

Optional Stricter Settings

Version 10 offers a more strict project setup when you create a new workspace with ng new.

ng new --strict

Enabling this flag initializes your new project with a few new settings that improve maintainability, help you catch bugs ahead of time, and allow the CLI to perform advanced optimizations on your app. Specifically, the strict flag does the following:

• Enables strict mode in TypeScript
• Turns template type checking to Strict
• Default bundle budgets have been reduced by ~75%
• Configures linting rules to prevent declarations of type any
• Configures your app as side-effect free to enable more advanced tree-shaking

Keeping Up to Date with the Ecosystem

As usual, we have made a few updates to the dependencies of Angular to stay synchronized with the JavaScript ecosystem.

• TypeScript bumped to TypeScript 3.9
• TSLib has been updated to v2.0
• TSLint has been updated to v6

We’ve also updated our project layout. Starting with version 10 you will see a new tsconfig.base.json. This additional tsconfig.json file better supports the way that IDEs and build tooling resolve type and package configurations.
