The+  default is @D.P.S.Search@ based on binary search.+- All array operations, pure or mutable are now based on a single, unified class. Mostly because+  mutable operations go via a data family anyway.++0.10.0.0+--------++- Rewrote Data.PrimitiveArray.Dense to accept all vector types using one+  interface. This is a breaking change, since @Unboxed@ becomes @Dense+  Data.Vector.Unboxed.Vector@, but now @Dense v@ accepts any @v@ as underlying+  storage vector. Breaking occurs only at user sites where the actual vector+  type needs to be specified. This tends to be very localized.++0.9.1.1+-------++- OrderedBits version bump++0.9.1.0+-------++- Arbitrary instance(s), field lenses that are probably not a good idea (don't use them!)++0.9.0.0+-------++- large-scale changes+- associated data families for bounds++0.8.1.0+-------++- inclusion of Upperlimit data family to simplify declaration of upper limits++0.8.0.1+-------++- PointL delays inlining to phase 0 for table filling.
