Hi all, It is my pleasure to announce the final release of SymPy 1.6.1. The wheel and sdist files for this release are already uploaded to pypi. You can install sympy 1.6.1 with:
$ pip install -U sympy There have not been many changes since 1.6.1. The full release notes are here: https://github.com/sympy/sympy/wiki/Release-Notes-for-1.6.1 There are no known backwards compatibility breaks or deprecations since 1.6. Mostly this release fixes a few small bugs that were uncovered in the 1.6 release. There is one particularly significant change: SymPy 1.6 changed the way that matrix arithmetic works to speed up some simple matrix operations that were unnecessarily slow. However although this lead to a speed up in most cases some more complicated cases were slowed down significantly: https://github.com/sympy/sympy/issues/19532 The changes to matrix arithmetic introduced in SymPy 1.6 have been reverted in SymPy 1.6.1. It is still possible to opt in to the new arithmetic but it is turned off by default: https://github.com/sympy/sympy/pull/19612 There are ways to speed up the simple cases without slowing down the more complicated cases so hopefully some part of that will be usable in 1.7: https://github.com/sympy/sympy/pull/18844 https://github.com/sympy/sympy/pull/19686 The following people contributed at least one patch to this release (names are given in alphabetical order by last name).
