ghc-prim 0.5.1.1 not on Hackage

The Stackage issue tracker just received an issue about ghc-prim 0.5.1.1. https://github.com/fpco/stackage/issues/3115 This version of the package has not been uploaded to Hackage, so: * The Stackage snapshots refer to 0.5.1.1 * The stackage.org documentation shows version 0.5.1.1 * `stack unpack` and `cabal unpack` both fail on ghc-prim-0.5.1.1 Also, it appears that the GHC 8.2.2 release notes still refer to ghc-prim 0.5.1.0. I'm happy to file an issue for this, but last time this popped up it was unclear if the issue should be filed on GHC Trac or the Hackage Trustees issue tracker. Michael
