+## GHC support policy
+
+We support at least three versions of GHC at a time. We are not aggressive about
+dropping older versions, but will generally do so for versions outside of the
+support window if either (1) maintaining that support would require significant
+effort, such as significant numbers of C pre-processor `ifdef` sections or Cabal
+`if` sections, or (2) the codebase could benefit significantly from features
+that are only available on more recent versions of GHC. We try to support new
+versions as soon as they are supported by the libraries that we depend on.
