- update to 1.12.1:
  * improved compatibility with NumPy 2.0 and CPython 3.12

  * https://github.com/sympy/sympy/wiki/release-notes-for-1.12
  * There was a regression in 1.7 that meant that __slots__
    would not work correctly for Basic instances and they
    would end up having __dict__. This also made it possible
    to set arbitrary attributes on Basic instances such as
    symbols which breaks immutability. This was fixed in
    1.7.1 to ensure that Basic instances do not have
    __dict__ and it is not possible to set attributes on
  * Fixed lazy iteration of series with expr.series(x,
     n=None) which was broken in the 1.7 release. (#20589 by
     @oscarbenjamin and @sachin-4099)
  * Updated documentation for sympy.stats.sample for seed
  * sympy.stats.sample now has an optional seed argument.
  * Random failures with sympy.stats.sample have now been
  * Modules and names that were accidentally importable from
    sympy are no longer importable. In sympy 1.6 importing and
    using these names would give a deprecation warning. In
    sympy 1.7 these names are removed. As an example from
    sympy import add would need to be from sympy.core import
    add or import sympy.core.add as add. (#19554 by
