doc: Add release notes for v2.1

* Rename Windows.h uses to windows.h
  * Comment out structured exception handling usage

Makes MinGW happier. Mostly the same as previous work by
Nicolas Dufresne <nicolas.dufresne@collabora.com>, with the exception
that we now don't try to invoke RaiseException which would fail in MinGW
as it raises a Windows structured exception.
