Changes

0.4.2

  • Add a library dependency on the doctests test suite

0.4.1

  • Revamp Setup.hs to use cabal-doctest. This makes it build with Cabal-2.0, and makes the doctests work with cabal new-build and sandboxes.
  • Drop (unused) hashable-extras dependency
  • Add NFData instance for HyperLogLog
  • Require GHC 7.8 or later

0.4.0.4

  • Support cereal 0.5 and safecopy 0.9.

0.4.0.3

  • Fixed doctest issues caused by vector 0.11
  • Unfortunately the herbie changes turned out to be flawed (due to issue mikeizbicki/HerbiePlugin#8). Rolling them back for now.

0.4.0.2

  • Fixed a haddock issue caused by the comments in the herbie code.

0.4.0.1

  • Added vector 0.11 support.
  • Incorporated some changes suggested by the HerbiePlugin.

0.3.4

  • Support generic-deriving 1.8. We no longer incur a generic-deriving requirement at all except on GHC < 7.6.

0.3.3.1

  • Support reflection 2

0.3.3

  • Added bytes and binary instances.
  • Compiles warning-free on GHC 7.10.

0.3.2

  • Simplified reifyConfig internals.

0.3.1

  • Added insertHash. This enables users of the 0.2 era version of hyperloglog to manually pick the hash used and load their old data.
  • Builds warning-free on GHC 7.10

0.3.0.1

  • Constraint bumps for lens and generic-deriving

0.3

  • Switched to SipHash, so the package actually works.

0.2.3.2

  • More #ifdef bugfixes

0.2.3.1

  • #ifdef bugfix

0.2.3

  • GHC 7.8 compatibility
  • Bumped cereal dependency.

0.2.1

  • Exported insert from Data.HyperLogLog.

0.2

  • Made compatible with lens 4

0.1

  • Ported Data.Analytics.Approximate.HyperLogLog from analytics into a separate package.
