[ITK-users] [ANN] ITK 4.9 Release Candidate 2 is ready for testing!

Wed Dec 2 10:26:19 EST 2015

On behalf of the Insight Toolkit community, we are proud to announce that
ITK 4.9 release candidate 2 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 v4.9rc02

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

A few selected highlights for this release:

* New Remote modules: the Cuberille module for smooth generation of meshes
from binary segmentation images, and the AnisotropicDiffusionLBR module
improved edge-preserving smoothing.
* Build your own ITK module outside the source tree, add continuous
integration testing on GitHub, and easily add Python wrapping for your C++
algorithms.
* Python wrapping, including Python 3, builds faster with a more standard
installation
* Improved performance of itk::Image::GetPixel and operations on
itk::VariableLengthVector’s
* Generate a FlatStructuringElement from an image
* Point-set registration with time-varying B-splines
* Module dependencies can now be specified as public / private / compile /
test

Please test the release candidate and share your experiences on the mailing
list, issue tracker, and Gerrit Code Review. The new module dependency
specification mechanism may unearth missing dependencies for projects that
use ITK COMPONENTS with the CMake find_package command.

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 35 contributors to this release. We
would especially like to recognize the new contributors: Mikhail Isakov,
Betsy McPhail, Alexander Leinoff, Shawn Waldon, Tobias Wood, Seun Odutola,
Hyun Jae Kang, Lucas Gandel, Adam Snyder, Junjie Bai, Pablo
Hernandez-Cerdan, Abhishek Tiwari, Eugene Prilepin, Zach Williamson, Luc
Hermitte, Laurentiu Nicola, and Floris Berendsen.

The final release is scheduled for mid-December.
