0.6.7001.0

• Fix bug with infinity in range bounds

• Fix incompatibility with GHC 8.4

0.6.7000.0

This is a pre-release of version 0.7.0.0. GHC >= 8.0 is required. It contains the following new important features

• A new API for manipulation, including ON CONFLICT DO NOTHING support for UPDATE

• Initial support for product types written in “Higher kinded data” style (but deriving of related functionality using TH or Generics is not yet provided).
