Update changelog for version 0.7.0
## Changelog
+### 0.7.0
+
+- Tuples from pairs to octuples have been made instances of `FromLuaStack` and
+ `ToLuaStack`.
+- New functions `dostring` and `dofile` are provided to load and run strings and
+ files in a single step.
+- `LuaStatus` was renamed to `Status`, the *Lua* prefix was removed from its
+ type constructors.
+- The constructor `ErrFile` was added to `Status`. It is returned by `loadfile`
+ if the file cannot be read.
+- Remove unused FFI bindings and unused types, including all functions unsafe to
+ use from within Haskell and the library functions added with 0.5.0. Users with
+ special requirements should define their own wrappers and raw bindings.
+- The module *Foreign.Lua.Api.SafeBindings* was merge into
+ *Foreign.Lua.Api.RawBindings*.
+- FFI bindings are changed to use newtypes where sensible, most notably
+ `StackIndex`, `NumArgs`, and `NumResults`, but also the newly introduced
+ newtypes `StatusCode`, `TypeCode`, and `LuaBool`.
+- Add functions `tointegerx` and `tonumberx` which can be used to get and check
+ values from the stack in a single step.
+- The signature of `concat` was changed from `Int -> Lua ()` to
+ `NumArgs -> Lua ()`.
+- The signature of `loadfile` was changed from `String -> Lua Int` to
+ `String -> Lua Status`.
+- The type `LTYPE` was renamed to `Type`, its constructors were renamed to
+ follow the pattern `Type<Typename>`. `LuaRelation` was renamed to
+ `RelationalOperator`, the *Lua* prefix was removed from its constructors.
+- Add function `tolist` to allow getting a generic list from the stack without
+ having to worry about the overlapping instance with `[Char]`.
