Breaking Changes

@angular-devkit/build-angular: use `sass` instead of `node-sass` (ce15899)

we no longer use `node-sass` by default, instead we use `sass` (dart-sass).

While in most cases this should not have an impact the generated code, dart sass has some differences from Ruby Sass. See https://github.com/sass/dart-sass#behavioral-differences-from-ruby-sass
for more details

If you wish to use node-sass instead of sass you need to install node-sass as a dev dependency.

npm users

npm install node-sass --save-dev

yarn users

yarn add node-sass --dev

Note: for larger Sass projects to avoid this performance hit you might want to install fibers. See: https://www.npmjs.com/package/fibers

Ref: TOOL-748

The sample you pasted above seems to have the BREAKING CHANGE: text removed. It should remain in the text because it is not obvious where it was before being removed.

Other than that LGTM, great work!

[alan-agius4]

@filipesilva the breaking change is the entire description, in the body there is only the breaking change text.
