Announcing the SimpleITK 2.5.5 Release!

Release Highlights

  • SimpleITK in R on the Windows operating system is available!

    SimpleITK 2.5.5 is the first official release to support building SimpleITK with R wrapping for all major operating systems. It is recommended to use the SimpleITKRInstaller to configure standard or custom builds without explicitly cloning the source code repository. Alternatively, R packages can be built from the SimpleITK source code directly by turning the WRAP_R flag on in the CMake configuration and following the R-specific installation instructions.

  • Added Support for R 4.6.0

  • Added Python Wheels for Free-Threaded CPython 3.14

    In the ABI section of the wheel filename, the t in cp314t indicates support for free-threading.

    The small t in the wheel filename is a significant change. The Global Interpreter Lock (GIL) is now optional in CPython (PEP 703). With this change, Python natively supports true multithreading, running threads in parallel on multi-core systems and not in a serial fashion managed by the GIL. Read more about free-threaded Python on python.org. While this change may affect your native Python code, and requires a compatible SimpleITK built wheel, the other wheels continue to unlock the GIL during ITK code execution for parallel processing.

  • ITK 5.4.6

    This distribution is based on the Insight Toolkit 5.4.6 release. Please see the ITK release notes for details.
