ITK 6.0 Beta 2 has been released!

Announcements

1

We are excited to announce the second beta release of ITK 6.0! This release introduces modern CMake module targets — a major build system modernization that makes it easier than ever to link ITK into your projects. Alongside this headline feature, Beta 2 delivers continued C++ modernization, Python enhancements, performance improvements, and expanded agentic engineering practices. As a beta release, we actively encourage the community to test and provide feedback as we approach the first Release Candidate. :rocket: :sparkles: :tada:

:flashlight: Highlights

CMake Module Targets

The most significant change in Beta 2 is the introduction of modern CMake interface library targets for every ITK module. Each module now exports a namespaced target — for example, ITK::ITKCommonModule, ITK::ITKImageGradientModule, or ITK::ITKThresholdingModule — enabling clean, explicit dependency management with proper transitive dependency resolution.

Pre-defined factory meta-modules simplify linking for common IO use cases:

  • ITK::ITKImageIO — all image IO modules (JPEG, PNG, NIFTI, DICOM, etc.)
  • ITK::ITKMeshIO — all mesh IO modules
  • ITK::ITKTransformIO — all transform IO modules

Before (ITK 5):

find_package(ITK REQUIRED)
include(${ITK_USE_FILE})

add_executable(HelloWorld HelloWorld.cxx)
target_link_libraries(HelloWorld ${ITK_LIBRARIES})

After (ITK 6):

find_package(ITK REQUIRED)
itk_generate_factory_registration()

add_executable(HelloWorld HelloWorld.cxx)
target_link_libraries(HelloWorld ITK::ITKCommonModule)

For projects that read images, simply link the IO meta-module:

find_package(ITK REQUIRED)
itk_generate_factory_registration()

add_executable(MyFilter MyFilter.cxx)
target_link_libraries(
  MyFilter
  PRIVATE
    ITK::ITKImageGradientModule
    ITK::ITKImageIO
)

UseITK.cmake (${ITK_USE_FILE}) is now deprecated in favor of these interface library targets. ITK can also be consumed via CMake FetchContent, illustrated in the new HelloFetchITK example.

For full migration details, see the ITK 6 Migration Guide — also a useful reference for both humans and AI agents working with ITK projects.

We especially welcome feedback on the CMake module targets during this beta period. Please report any issues you encounter with the new build system on GitHub.

C++ Modernization

  • VariableLengthVector gains a std::vector-like interface: front(), back(), data(), and a (length, value) constructor
  • FixedArray gains front(), back(), and empty() member functions
  • ImageConstIterator::ComputeIndex() added as the replacement for GetIndex() (now deprecated), with performance benefits from avoiding redundant offset table lookups
  • New itk::MakeIndexRange utility functions for convenient index-space iteration
  • SobelOperator extended to N-D with corrected 3D coefficients and a UseLegacyCoefficients option
  • NumericTraits::GetLength is now constexpr
  • Replaced vnl/vnl_sample.h with standard <random> across tests
  • Expanded use of constexpr, [[nodiscard]], aggregate initialization, and range-based for loops

Python Enhancements

  • Python 3.10+ is now required for wrapping
  • New ITK_PYTHON_RELEASE_GIL build option enables GIL release during ITK filter execution
  • Updated bundled pygccxml to v3.0.2

Performance Improvements

  • Tuned ImageRegionRange copy used in CastImageFilter
  • IndexRange iterators made significantly faster via m_Position data member
  • ImageRegionRange bypasses OffsetTable[0] (which is always 1)
  • Prefer “with index” iterators when the index is used in each iteration, avoiding redundant ComputeIndex() calls

Third-Party Library Updates

  • GDCM 3.2.2, double-conversion 3.4.0, Expat, VXL, NrrdIO, CastXML v2026.01.30

Platform & CI Updates

  • Updated CI to Windows 2022 images
  • Added Linux ARM CI testing
  • Migrated to macOS 15 runners (Apple Silicon)
  • Support building with system Eigen3 >= 5
  • New ITK_FREEZE_REMOTE_MODULES option to prevent remote module updates during build

Remote Module Updates

  • CudaCommon v2.0.0 with __cuda_array_interface__ support for interoperability with CuPy and PyTorch
  • RTK major updates: new Python applications, CUDA improvements, spectral CT documentation
  • Remote modules updated for CMake modernization (itk_module_add_library)

Agentic Engineering

ITK continues to advance its agentic engineering practices, improving the developer experience with agent-friendly workflows, better CI, and review agents. In this release, copilot-swe-agent[bot] contributed the GIL release feature, NumericLocale GoogleTest coverage, bug fixes for imread and locale-dependent NRRD parsing, and more. The AGENTS.md guide and GitHub Copilot setup workflow continue to be refined.

Now is as great a time as ever to contribute to ITK and learn from an active and friendly community of experienced medical imaging professionals.
