[Insight-developers] ITK 4.0.0 is available for download!

[Matt McCormick]

We are happy to announce the release of ITK version 4.0.0!

Download links for release tarballs can be found at the project download page:

  http://www.itk.org/ITK/resources/software.html

The revision is identified in the Git repository with the tag
“v4.0.0”.  To obtain the source code for the 4.0.0 release with Git,

  git clone http://itk.org/ITK.git
  cd ITK
  git checkout -q --detach v4.0.0


ITKv4 marks a huge step forward for the project as it make strides in
improving the software process, revising, simplifying, and
accelerating the toolkit.  According to Ohloh, there are currently 74
active contributors to the “mature, well-established codebase” with
2.5M lines of code amounting to 713 person years and $39M of
development.  Highlights of the advances in ITKv4 are found here:

Note that the ITKv4 effort, supported by the National Library of
Medicine (NLM), is still on-going, and improvements will continue to
be added until June 2012.  For more information, see the release
schedule:

  http://www.itk.org/Wiki/ITK_Release_4/ReleaseSchedules

*IMPORTANT*: The new classes and methods are still subject to
improvement with further testing, and a moratorium has been placed on
backwards compatibility of API changes until June, 2012.

For help in transitioning from ITKv3 code, please see the Migration guide:

  http://itk.org/migrationv4/

and note the ITKV3_COMPATIBILITY CMake configuration variable, if you
want to force ITKv4 to behave closer to ITKv3.


Congratulations to the members of the ITKv4 development team

We are particularly thankful to Hans Johnson, Bill Lorensen, and Gaëtan Lehmann.
