Announce: passagemath 10.6.1.rc1 - modularized pip-installable fork of Sage

[Matthias Koeppe]

Dropped support for Python 3.9

The passagemath-10.6.x series has dropped support for Python 3.9. This is the system Python on Debian bullseye (end of standard support: 2024-08) and Ubuntu focal (2025-04), and the Python shipped with Xcode on macOS. When installing passagemath in the traditional Sage-the-distribution mode on these systems, a suitable Python, now version 3.13.5, will be built from source.

The language standard for the Sage library is now Python 3.10 plus backport packages, most importantly typing_extensions.

The supported versions of Python are now 3.10.x–3.13.x. Support for Python 3.14 will be added either later in the passagemath-10.6.x series or in the passagemath-10.7.x series.

Initial support for GCC 15
