11# Supported GHC Versions
22
3−This table shows which versions of GHC are defined, built by CI, and tested.
4−If you use a combination of nixpkgs version and GHC version which is built by our CI, you should get cache hits from our cache.
53
6−The "nixpkgs versions" refer to the versions that `haskell.nix` provides; if you use your own version of nixpkgs you will likely not get cache hit
4+The following GHC versions are defined in `haskell.nix` (i.e. there is a derivation for them even if it isn't necessarily cached):
5+- 8.4.4
6+- 8.6.{1,2,3,4,5}
7+- 8.8.{1,2,3,4}
8+- 8.10.{1,2,3}
