Quoting the release note entry: | Warnings can now be controlled with `-W(no-)...` flags in addition to | the old `-f(no-)warn...` ones. This was done as the first part of a | rewrite of the warning system to provide better control over warnings, | better warning messages, and more common syntax compared to other | compilers. The old `-fwarn...`-based warning flags will remain | functional for the forseeable future.
