The release candidate 10.8.5rc0 of passagemath-ecl now ships ECL 26.3.27 in its binary wheels on PyPI for Linux and macOS. https://pypi.org/project/passagemath-ecl/10.8.5rc0/ I would welcome testing of this prerelease by experienced ECL users. If anyone knows a Jupyter kernel that works with ECL, please let me know; I would like to ship it with passagemath-ecl. https://github.com/passagemath/passagemath/issues/1394 passagemath-ecl is one of the pip-installable components of the modularized Sage library, developed by the passagemath project (https://github.com/passagemath). It supports CPython 3.10-3.14 on Linux and macOS and provides binary wheels for these platforms on PyPI. Matthias -- Matthias Koeppe -- http://www.math.ucdavis.edu/~mkoeppe
