Hi all SymPy community,
It is with great sadness that I bring the news that Kalevi Suominen
(@jksuom on GitHub) passed away on the 4th of March. Kalevi's son
Risto passed on this news to me and some others by email yesterday.
I never met Kalevi in person but we had many conversations online over
Hi Anton,
To be clear I am not against adding SymPy to SPEC 0. I just want to
understand what this means in practice. Presumably if SymPy is added
there then people will have some expectation that it means something
somehow.

Hi Anton,
What difference does it make to you in practice whether or not SymPy
is listed in SPEC 0?
SymPy does not really support old versions with maintenance releases
so it does not really have a "support cycle" in the sense that SPEC 0
seems to describe. There can be a bugfix release shortly
You don't need to worry about those errors. They are not related to
the changes in your PR and any PR can be merged even if those tests
fail. It looks like those same errors are showing on all PRs right
now.

Hi all,
It is past time that a new release of SymPy is needed. Let's get SymPy
1.13 out ASAP.
I had been meaning to put out a bugfix release of SymPy 1.12.1 because
of a few things that have been fixed since SymPy 1.12 but it didn't
happen. In particular compatibility with Python 12's ast module

Hi Aaron,
I think we should start by removing everything from the ideas page and
moving it to an "old ideas" page with a clear note indicating that
some might still be relevant but others are likely not. I don't think

Hi Shishir,
There is a guide for contributing to SymPy here:

The main thing is to find something that you can work on to improve
SymPy. The starting point for that is usually to look at the open
issues on GitHub, especially those

"symbols". You might want to try using Spyder which can show you the

I have a new blog post following the last one:

Hi all,
There are two open PRs discussing the potential use of pre-commit and
pre-commit.ci in SymPy:
https://github.com/sympy/sympy/pull/24908

There already is mathics which is a Wolfram Language interpreter that
is based on SymPy. It would seem a bit odd to create a new one.

That's a separate issue that should also be fixed.

It would be better to have a simple way of disabling integration in dsolve.

Sometimes things sort of work in some cases but don't really work
properly and it isn't possible to fix them

Hi Simon,
Yes, I think that SymPy 1.11 was released shortly before CPython 3.11.
It was tested against 3.11 through all the beta versions etc.
I don't immediately have 3.11 to hand. Does pip still install SymPy
from PyPI under 3.11?
