parsec 3.1.14.0

- Add `parseFromFile` to `Text.Parsec.Text.Lazy` and `Text.Parsec.Text` (#103, #104).

- Clarify Haddock documentation in various places (#105,#101,#102).

- Add support for `base-4.13`.

parsec 3.1.14.0 release candidate

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.

parsec 3.1.12.0

- Add `MonadFail` instance for `ParsecT`
- Add `Semigroup`/`Monoid` instances for `ParsecT` (#80,#82)
- Fix space leak in Applicative/Monad interface (#37)
- Add `parserTrace` and `parserTraced` combinators for debugging.
