Release 4.2.1 was a bugfix/patch release.  This release addressed some critical
build and performance issues.

* Important performance gains were the result of efforts by community members
  Bradley Lowekamp and Kent Williams through the removal of filter
  GetInput/GetOutput calls in inner loops.
* Compilation errors were fixed for Visual Studio 2012.
* A number of CMake/WrapITK issues were addressed to improve Python wrapping on
  Windows.
* There were also other assorted fixes.
* The next minor feature release, v4.3.0, is scheduled for December.
