ANN: cabal-install 1.22, 1.20 & 1.18 releases

[Ryan Thomas]

Hi all,

I have released 1.22.8.0, 1.20.2.0 and 1.18.2.0 of cabal-install, after a
fix was found for #3003 <https://github.com/haskell/cabal/issues/3003>:

If you encounter an error similar to the following when running
`cabal install cabal-install` or 'cabal install Cabal':

/tmp/cabal-tmp-7012/Cabal-1.22.6.0/Distribution/Version.hs:135:10:
    Duplicate instance declarations:
      instance Binary Version
        -- Defined at
/tmp/cabal-tmp-7012/Cabal-1.22.6.0/Distribution/Version.hs:135:10
      instance [safe] Binary Version
        -- Defined in ‘binary-0.8.0.0:Data.Binary.Class’

try running 'cabal install -j1 Cabal' to work around the 'binary-0.8'
compatibility issue.


Cheers,

ryan
