Wrong information about the previous version of the time library in GHC 7.10.1 RC2 release notes
From https://downloads.haskell.org/\~ghc/7.10.1-rc2/docs/users_guide.pdf:
Version number ... (was 1.4.1)
The right information is:
Version number ... (was 1.4.2)
(Note also that the information about the (previous) version of the time library is wrong in the release notes of GHC 7.8.3 and GHC 7.6.1).
