ITK 4.8.0 Release Candidate 1 is ready for testing!

June 11, 2015

On behalf of the Insight Toolkit community, we are proud to announce that ITK 4.8.0 release candidate 1 has been tagged and is available for testing! Please take this opportunity to test the new features in the release candidate.


To obtain the source code,


 git clone

 cd ITK

 git checkout -q –detach v4.8rc01


For more details, please see the Git documentation.



A few selected highlights for this release:


  • New remote modules: BridgeNumPy, LabelErodeDilate, and ParabolicMorphology.

  • itk::FFTPadImageFilter to automatically pad images for the FFT implementation’s supported greatest prime factor

  • Additional point set registration capabilities.

  • More modules can be built as shared libraries.

  • GDCM, MetaIO, KWSys, MINC have been updated to their latest upstream versions.

  • Python wrapping is in excellent shape and works with the latest GCC, Clang, and MSVC.

  • Experimental cross-compilation support for Windows (MinGW-w64), ARMv6 (Raspberry Pi), ARMv7 (Android), ppc64le (POWER8), and JavaScript (Emscripten).

A more complete, detailed set of release notes will follow in subsequent release candidates.


Please test the release candidate and share your experiences on the mailing list, issue tracker, and Gerrit Code Review. Since GDCM has seen a major upgrade to the latest version, please exercise DICOM IO, and be on the lookout for regressions.


An Experimental build, which demonstrates how the test suite performs on your local build system, can be submitted to the dashboard with:


 mkdir ../ITK-build

 cd ../ITK-build

 cmake ../ITK

 ctest -j 4 -M Experimental  -T Configure -T Build -T Test -T Submit

Notify the mailing list if there are any unexpected failures.  Testing your own applications against the RC is also appreciated.


Congratulations and well done to the 31 contributors to this release. We would especially like to recognize the new contributors, David Froger, Cyril Mory, Dzenan Zukic, Ivan Setiawan, Jan Bergmeier, Rolf Eike Beer, Davis Vigneault, Gary JIA, and Alexander Hewer.


The final release will be approximately three weeks from now.
