Reading the file with 12000+ examples is slow as it's deserialized with
'read'.

Use bases built-in float/word32 and double/word64 casts

Travis keeps breaking due to its very fragile build script.
Switching to an approach which I hope will be more robust.

Only use recent version of cabal when building for all GHC versions.
This means we no longer test older cabal install binaries.

cabal-install is unable to come up with a build plan for the tests and
benchmarks. The problem seems to be that building binary's
tests/benchmarks requires having binary, which is what we're trying to
build. Cabal doesn't seem to separate the lib/tests/benchmarks into
distinct build units, so it fails to come up with a plan.

To work around this, when building on travis, we rename the binary
library. With a new name, cabal can find a plan and run the tests.

Remove GHC 7.4.2 and 7.6.3 from the testing matrix.
They fail with this new build setup for a reason I haven't investigated.

Remove a redundant catch-all clause

Handle {Int,Word}32Rep

The clause will be rendered redundant by [GHC MR 963](ghc/ghc!963).

Remove 7.4.1 as it's broken upstream.

Prepare 0.8.7.0

Haddock markup fixes

  * Use the standard `@since` notation (since it plays well with
    re-exports in other packages)
  * Use `@ ... @` for monospacing things that aren't identifiers
  * Qualify some linked identifiers (so that they actually link)

'Binary (NonEmpty a)' should 'fail' on empty lists

Compatibility with future ghc-8.8/base-4.13

Typofix

Remove unused imports.

Add support for Int16#, Word16#

Due to a bug in ghc, some unused imports do not yield warnings.
This commit will remove such unused imports in preparation for
the ghc bug fix (see https://ghc.haskell.org/trac/ghc/ticket/13064).

Add GHC 8.6.1 to travis and docker.

Add support for Int8Rep/Word8Rep added in GHC 8.7

The failure should be in the context of 'MonadFail'.

There was no breaking changes in version 0.10.0.0,
so let's also release under 0.8.6.0.
