 - Removed
   - Python 3.6 support
   - Support for text file objects as `load` input. Use binary file objects instead.
+  - First argument of `load` and `loads` can no longer be passed by keyword.
 - Improved
   - Raise an error when dotted keys define values outside the "current table".
     Technically speaking TOML v1.0.0 does allow such assignments
