Update changelog for version 1.2.0
## Changelog
+### 1.2.0
+
+Release pending
+
+- New module `Foreign.Lua.Call`: the module offers an alternative
+ method of exposing Haskell functions to Lua. The focus is on
+ maintainability: types and marshaling methods are made explicit;
+ the possibility of adding documentation and parameter names
+ improves error messages and allows for automatic documentation
+ extraction.
+
+ Work on this module is ongoing; the interface is likely to
+ change. Suggestions and feedback are welcome.
+
+- New types `Module`, `Field`, and new functions `registerModule`,
+ `preloadModule`, `pushModule`, and `render` exported from
+ `Foreign.Lua.Module`: this builds on the new `Call` module and
+ allows the creation of documented modules as well as automatic
+ generation of Markdown-formatted module documentation.
+
+- Export new items `nth` and `top` from Foreign.Lua.Core and
+ Foreign.Lua. They are short-hands for `nthFromTop` and
+ `stackTop`.
+
+- Performance improvements: Calling of Lua functions and creation
+ of Haskell data wrapping userdata has been sped up by about 10%.
+ This is mostly due to using of previously missed optimization
+ opportunities.
+
+- All foreign imports have been moved to into the new
+ `Foreign.Lua.Raw` module. This module will replace the current
+ `Foreign.Lua.Core` module in the future and will be distributed
+ as a separate package (likely starting with the 2.0 release);
+ the remaining parts of the current `Core` module will be
+ promoted one level in the module hierarchy.
+
+ The `Raw` module can be used whenever the full power of HsLua is
+ not needed.
+
+- Error-signaling of API wrapper functions has been changed:
+ instead of returning special integer values, functions now take
+ an additional pointer argument, which is set to the status
+ result of the computation.
+
+ The `Failable` type in Core.Error is no longer needed and has
+ been removed.
+
+- CI builds now include GHC 8.8 and GHC 8.10, ensuring that all
+ GHC 8.* versions are supported.
