[ITK-users] [ANNOUNCE] ITK 4.8.0 Release Candidate 3 is ready for testing!

[Matt McCormick]

On behalf of the Insight Toolkit community, we are proud to announce
that ITK 4.8.0 release candidate 3 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 http://itk.org/ITK.git
  cd ITK
  git checkout -q --detach v4.8rc03


For more details, please see the Git documentation [1].


A few selected highlights for this release:

- New remote modules: BridgeNumPy, LabelErodeDilate,
ParabolicMorphology, MinimalPathExtraction
- 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 [2]
with:


  mkdir ../ITK-build
  cd ../ITK-build
  cmake ../ITK
  ctest -j 4 -M Experimental  -T Configure -T Build -T Test -T Submit


Visual Studio builds must also add “-C Release” to the ctest command.

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 one week from now.
