Breaking Changes

@​angular/cli

• The ng commands will no longer automatically detect and use cnpm as the package manager. As an alternative use the .npmrc file to ensure npm uses the cnpm registry.

@​angular/build

• • TypeScript versions older than 5.9 are no longer supported.
• The javascriptEnabled option for Less is no longer supported. Projects relying on inline JavaScript within Less files will need to refactor their stylesheets to remove this dependency.

Breaking Changes

forms

• The shape of SignalFormsConfig.classes has changed

  Previously each function in the classes map took a FieldState. Now
  it takes a Field directive.

  For example if you previously had:

  provideSignalFormsConfig({
    classes: {
      'my-valid': (state) => state.valid()
    }
  })
  

  You would need to update to:

  provideSignalFormsConfig({
    classes: {
      'my-valid': ({state}) => state().valid()
    }
  })
