passagemath-10.6.40

MSYS2 packages for Windows on x86_64 and ARM

The downstream effort to package passagemath for MSYS2 has reached an important milestone. All packages for which passagemath provides Windows wheels are now available as MSYS2 packages, too.

After installing MSYS2, use pacman to install some of the available packages, for example:

$ pacman -S mingw-w64-ucrt-x86_64-python-passagemath-{cmr,repl}

Then start the Sage REPL:

$ sage
...
sage: from passagemath_cmr import *

First binary wheels for Windows on ARM

FLINT has been upgraded to version 3.4.0; blog post, release notes.

New package for linear inequality systems

The new package certlin by @MarcusAichmayr computes certificates for the solvability or insolvability of systems of linear inequalities.

passagemath-10.6.37

New top-level import names for the modularized pip-installable packages

The top-level bindings of each of the modularized pip-installable packages of the Sage library can now be accessed using the same import name as the distribution name. This is, in particular, convenient when using the marimo notebook, as marimo will infer what package needs to be installed from PyPI based on the import name.

For example, for passagemath-modules, you can use

from passagemath_modules import *

This is equivalent to from sage.all__sagemath_modules import *. Likewise, for the passagemath-standard distribution, you can now use

from passagemath_standard import *

instead of from sage.all import *.

All of the above is intended for interactive use only. Libraries should instead import specific bindings from the sage namespace.

Downstream packages for MSYS2 / mingw-w64 available

A downstream packaging effort for Windows (MSYS2 / mingw-w64) has begun, see msys2/MINGW-packages#24738. See the MSYS2 package search for the passagemath packages already available.
