Changes

0.4.0.1

  • Added vector 0.11 support.

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
