parsec 3.1.13.0
- Add official support for [`SafeHaskell`](http://downloads.haskell.org/~ghc/latest/docs/html/users_guide/safe_haskell.html)
**NOTE**: This is the first version whose `SafeHaskell` properties
have become an intentional part of the API contract; previous
versions were merely accidentally safe-inferred (or not depending
on various factors; in other words, this was a fragile
property). If you rely on `SafeHaskell` to consider module imports
from `parsec` *safe*, this is the first version of `parsec` which
actually guarantees a well-defined state; you can declare this
requirement by either specifying
build-depends: parsec >= 3.1.13.0 && < 3.2
or, starting with `cabal-version:2.0`, via
build-depends: parsec ^>= 3.1.13.0
- Drop support for GHC 7.0, GHC 7.2, and GHC 7.4.1; support window
starts with GHC 7.4.2.
