Hi,
Everything is built now in f30-ghc: waiting for releng to tag the builds to f30 and f31.
With the move to ghc-8.4 I am planning to retire the following groups of packages:
[enumerator is long deprecated and no longer builds out of the box]
ghc-attoparsec-enumerator
ghc-blaze-builder-enumerator
ghc-enumerator
ghc-zlib-enum
[FTBFS]
ghc-bytestring-trie
haskell-platform [more or less deprecated - no release for 8.4.4]
[weldr packages FTBFS since 8.2]
ghc-bdcs-api
ghc-bdcs
ghc-conduit-combinators
ghc-content-store
[Elliot: this seems no longer needed (has a new dep on cabal-plan) - ghc-mod is no longer maintained or in Fedora]
ghc-cabal-helper
[got retired recently, but I built bustle without it, so maybe we don't need it after all]
ghc-hgettext
[the following important core libraries now included in ghc]
ghc-mtl
ghc-parsec
ghc-stm
ghc-text
