Changes

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

  • Builds warning-free on GHC 7.10

0.3.0.1

  • Constraint bumps for lens and generic-deriving
