======
derive-topdown-0.0.0.9
--------------
- `0.0.0.9`
* Changed API for `strategy_derivng(s)`. Deriving strategy should be specified first as the default grammar of `deriving`.
* Provided `deriving_with_breaks` function so that one can specify the types that prevent further standalone deriving declarations from generating process. This is mainly for `Generic` class. See the test of deriving `Generic` for `HsModule`.
* Fixed Strategy deriving problem. Deriving with NewtypeStrategy on data type defined by `data` keyword will be ignored.
* Fixed problem with class context generation for phantom types. Phantom types will not be in the context now.
* Fixed `ArrowT` problem. It should be not a type variable and should appear in the context.
* Handled data constructor which contains explicit `forall`.
* Added test. It generates class instances for data types in `template-haskell` and `haskell-src`.
derive-topdown-0.0.0.7
--------------
- `0.0.0.7` is a more carefully implemented version of derive-topdown.
All APIs are **totally** changed compared with 0.0.0.2. Originally it did not work with types that contain type synonyms and polymorphic types. It can work for most common cases in this version now.
derive-topdown-0.0.0.2
--------------
- Fixed some cabal file and API problems.
derive-topdown-0.0.0.1
--------------
- This is only an experimental implementation for deriving class instances from top to bottom.
There is a lot of deficiencies.
