Description

We are pleased to announce the release of ITK 5.4.3, the latest maintenance update for this cross-platform, open-source toolkit supporting N-dimensional scientific image analysis with spatially-aware algorithms. 🎉 🍻 🥳 This patch release addresses several key issues identified since ITK 5.4.2 while maintaining API stability.

🔦 Highlights

As a maintenance update following 5.4.2, version 5.4.3 incorporates critical improvements including:

  • Bug Fixes: Resolved issues affecting the default number of threads, particularly in multi-threaded image processing pipelines where thread limits were not respected, and corrected the b-spline size calculation for closed parametric dimensions, ensuring accurate interpolation in applications such as 3D image registration and deformation modeling.
  • License Fixes: Removed unused VNL Netlib rpoly files to ensure compliance with our Apache 2.0 licensing requirements.
  • Software Guide Updates: Spelling corrections for the ITK Software Guide.
  • Doxygen Documentation: Updated Doxygen documentation to reflect the latest changes and improvements in ITK, including links to the ReadTheDocs site.
  • Remote Module Updates: Improvements to the LabelErodeDilate and MeshToPolyData remote modules, including bug fixes and enhancements.

A full list of changes can be found in the changelog below.
