ITK Release 5.0 Beta 3#
We are happy to announce the Insight Toolkit (ITK) version 5 Beta 3 release! :tada: This release celebrates the community’s migration to GitHub. :octocat: As a true open source project, community participation is a high priority. :handshake: Our migration to GitHub facilitates collaboration with the broader scientific open source community. :microscope:
This release also includes major improvements in the areas of performance and third party libraries. A new, experimental
ImageRange class enables iteration over an image’s pixels in a modern, performant way. Fundamental ITK data structures were improved to enabled compiler optimizations for Plain Old Data objects. VXL was modernized to C++11, and Eigen is now available in the toolkit; ITK’s gradual transition from VXL to Eigen for linear algebra has begun.
In addition, four new remote modules are available, FFT’s can be computed on the GPU via cuFFTW, and ITK Python’s
itk.imread now supports image series. More information can be found in the feature summary below.
For an overview of ITK 5’s transition to modern C++, performance-related changes, and the new, Pythonic API, see the ITK 5 Alpha 1: Modern C++, ITK 5 Alpha 2: Performance, and ITK 5 Beta 1: Pythonic Interface release announcements.
GitHub now hosts the official ITK, ITKExamples, and ITKSoftwareGuide Git repositories:
The InsightSoftwareConsortium GitHub Organization is currently home to 88 other ITK-related repositories. Many of these repositories are externally developed ITK modules. If you would like create a new repository or transfer a repository to the InsightSoftwareConsortium GitHub organization, let us know on ITK’s Discourse discussion forum.
Documentation on how to contribute has been updated and improved. Contribution documentation is available in the ITK Software Guide and as Markdown files in the source code repository, browsable in GitHub’s web interface. Our CONTRIBUTING.md file is a starting point for contributors. We also have a Git cheatsheet for quick reference.
Our Code of Conduct describes our motivation to build impactful, open source image analysis software through a welcoming and productive community. The Code of Conduct also describes our values: to be open, welcoming, inclusive, civil and considerate, respectful, collaborative, careful in the words that we choose, responsible, and inquisitive. We expect community members to lead by example, but we also define a set of unacceptable behaviors and mechanisms to enforce conduct violations.
To guide submission of pull requests and issues, we created templates used when issues and pull requests are opened. Release notes from previous releases were migrated from the Wiki; release notes can be browsed in repository Markdown files.
Plans for upcoming releases can now be found in the project GitHub Milestones. Release artifacts will now be published on ITK’s GitHub Releases as opposed to Sourceforge. Release artifact archives are now also available in the ITK data.kitware.com Girder Collection.
./Utilities/SetupForDevelopment.sh script now guides repository configuration for GitHub contributions. Git client-side hooks help submit a well-formatted commit message. Git aliases,
pr, are provided to submit pull requests for review and download submitted pull requests for local testing.
A new cross platform script,
ITK/Utilities/UploadBinaryData.sh, is available to upload binary testing data. This script, invoked directly or through the
data-upload alias, performs an authenticated upload to data.kitware.com and generates an ExternalData content link to avoid inflation of the source code repository’s size. This script can be used to upload testing data for ITK or an externally developed module.
A static archive of our previous code review system, the https://review.source.kitware.com/ Gerrit Code Review instance, was created to preserve the code review discussions for nearly 24,000 changes on ITK and other Kitware supported projects.
Continuous integration testing ensures the continued quality and productive development of the toolkit. CircleCI and Azure Pipelines CI testing run over 2,800 regression tests on Linux, macOS, and Windows for both C++ and Python builds. Pull requests content is checked by ghostflow-director to prevent integration of large files, etc.

The ITK 5 Migration Guide is available to help transition a code base from ITK 4 to ITK 5. Please discuss your experiences on Discourse. We are approaching the 5.0.0 final release! The next release will be the first ITK 5 release candidate; it is scheduled for the end of January.
