What's new in Angular CLI 12.1?
Angular CLI 12.1.0 is out!✨
If you want to upgrade to 12.1.0 without pain (or to any other version, by the way), I have created a Github project to help: angular-cli-diff. Choose the version you’re currently using (11.0.0 for example), and the target version (12.1.0 for example), and it gives you a diff of all files created by the CLI: angular-cli-diff/compare/12.0.0…12.1.0.
It can be a great help along with the official
ng update @angular/core @angular/cli command.
You have no excuse for staying behind anymore!

--configuration production in the scripts section of the
When generating a component, it is now possible to specify
style=none to avoid generating a style file.
Previously it was only possible to specify
all of which were generating a style file.
Experimental faster builds
An experimental persistent build cache can be enabled by running:
NG_PERSISTENT_BUILD_CACHE=1 ng serve
This should improve cold build times, as it causes
node_modules to be treated as immutable by Webpack.
