Constants
const A = 'a';
const B = 'b';
Will become
const A = 'a';
const B = 'b';
The spacing of one line will still be enforced for methods and properties, just not for constants.
Strict types
Strict types will now by default be enabled for all files in a project. Make sure to disable the rule if you're working with a legacy project that breaks in such a case.
