### `GHC2021`
|
|
|
|
|
|
When GHC or GHCi is invoked, it will now enable the language extensions included as a part of `GHC2021`. See [here](https://github.com/ghc-proposals/ghc-proposals/blob/f0b86694de131a89a26e12253d922fba186654f2/proposals/0380-ghc2021.rst#id2) for the full list of language extensions. If your project no longer compiles with `GHC2021`, you can disable the appropriate language extensions as needed (e.g., use `{-# LANGUAGE NoPolyKinds #-}` to disable `PolyKinds`).

|
|
|
|
Note that this is unlikely to affect projects with `.cabal` files, as they typically use the `Haskell98` or `Haskell2010` sets of language extensions.
