Questions about Angular version 9, the web framework from Google.

New Breaking Changes

  • Angular now compiles with Ivy by default. See Ivy compatibility section.

  • CLI apps compile in AOT mode by default (which includes template type-checking). Users who only built with JIT before may see new type errors. See our template type-checking guide for more information and debugging tips.

  • Typescript 3.4 and 3.5 are no longer supported. Please update to Typescript 3.6.

  • tslib is now listed as a peer dependency rather than a direct dependency. If you are not using the CLI, you must manually install tslib, using yarn add tslib or npm install tslib --save.

See the changelog for latest version information.

As of December 2019, the current RC version is 9.0.0-rc.7

Consider using the Update Guide for tips before changing the version.
