+synopsis: Reimplementing `cabal check`
+packages: Cabal
+prs: #8427
+issues: #7423
+
+description: {
+
+- For `cabal-install` users: `cabal check` do not warn on -O2 or similar
+  options if under an off-by-default cabal flag.
+- For `Cabal` the library users: `checkPackage` signature has been simplified,
+  you do not need to pass a specific configuration of the package, since
+  we do not flatten GenericPackageDescription no more.
+- For `Cabal` the library users: `checkPackageFileNames` has been removed,
+  use `checkPackageFiles` instead.
