Use `Alternative` or `Monad` + `MonoidK` instead. * `CartesianBuilder` (i.e. `|@|`) syntax is deprecated, use the apply syntax on tuples instead. E.g. `(x |@| y |@| z).map(...)` should be replaced by `(x, y, z).mapN(...)`. If you are getting "`mapN` not found" error message, it could be due to SI-2712, see the 3rd migration item above. * Apply syntax on tuple (e.g. `(x, y, z).map3(...)`) was moved from `cats.syntax.tuple._` to `cats.syntax.apply._` and renamed to `mapN`, `contramapN` and `imapN` respectively. * The creation methods (`left`, `right`, `apply`, `pure`, etc.) in `EitherT` were improved to take less
