Additionally, the package requires the following patch to compile once the new base package is allowed:

@jgoerzen @bjornbm

please let us know if you need help cutting a release, and or if you'd like me or another hackage trustee to do a quick fix update using the patch @davean shared.

a large number of things seem to depend on missingH in a number of ways, and its always nicer to make sure tools and libs upgrade smoothly with a new ghc release :)

[jgoerzen]

Please feel free to make a release. My time for Haskell is pretty limited right now.

[jgoerzen]

I would also be fine if somebody would like to adopt MissingH

[cartazio]

Could you add Davean https://hackage.haskell.org/user/davean To the uploaders group for missingH so we can do the NMU?

Many thanks.
