[racket-dev] Release Announcement for v6.1.1

For TR:

* Exception handling changed to be safe. This may break existing
  programs that rely on unsafe behavior.

* Exports from the GUI and framework libraries have types, and can be
  used transparently from typed programs.

* Casts and predicates are supported in typed regions.
