@angular-devkit/schematics

Node.js v20 is no longer supported. The minimum supported Node.js versions are now v22.22.0 and v24.13.1.

The @angular-devkit/architect-cli package is no longer available. The architect CLI tool has been moved to the @angular-devkit/architect package.

The experimental @angular-devkit/build-angular:jest and @angular-devkit/build-angular:web-test-runner builders have been removed.

The @angular/build:dev-server (ng serve) now assigns the highest priority to the PORT environment variable. This value will override any port configurations specified in angular.json or via the --port command-line flag. This includes the default port 4200.

istanbul-lib-instrument is now an optional peer dependency.

The server no longer falls back to Client-Side Rendering (CSR) when a request fails host validation. Requests with unrecognized 'Host' headers will now return a 400 Bad Request status code. Users must ensure all valid hosts are correctly configured in the 'allowedHosts' option.

The splitting option in the unit-test builder is deprecated as it is no longer needed with Vitest 5.

stringToFileBuffer and fileBufferToString are deprecated. Use standard Web APIs (TextEncoder and TextDecoder) instead.

Webpack builders in build-angular are deprecated. Use @angular/build builders instead.

Webpack builders in build-webpack are deprecated. Use @angular/build builders instead.
