# Revision history for red-black-record
## 2.0.2.2
- Improved compilation times for type-level deletion.
## 2.0.0.0
- BREAKING CHANGES
- The constructors for the type-level map are now hidden.
- The name of the type-level map has changed from RBT to Map, to
de-emphasize implementation details.
- Added the "Deletable" typeclass with de "delete" and "winnow" methods.
- Solved bugs with coloring/balancing, added new tests.
- Data.RBR.Internal is still exported, but it doesn't appear in the Haddocks.
It appears that Haddock doesn't play well with reexported-modules sections in
Cabal.
## 1.1.0.0
- Field and Branch type families to help speed up type-level computations.
Apparently, having identical invocations of a "costly to compute" type family
in a signature slowed things down.
## 1.0.0.2
- Improved compilation times for getters by refactoring `KeyHelper`.
## 1.0.0.0
- First version. Released on an unsuspecting world.
