Hi SymPy users and contributors,
It is my pleasure to announce the *beta release* of SymPy 1.5. This is
is intended for advance testing rather than production use.
I have just made version 1.5b1 available to install as a pre-release
from PyPI. You can install this with
$ pip install --pre sympy
This will not be a long-lasting beta phase. The final release of 1.5
is expected in a few weeks. I hope that making a beta release
available via pip will encourage as many people as possible to try
this out and report any regressions before the final release.
The release notes for SymPy 1.5 can be found here:
https://github.com/sympy/sympy/wiki/Release-Notes-for-1.5
Note that there are some features that are deprecated and also some
changes that are not backwards compatible. We try to ensure backwards
compatibility and to use a deprecation process wherever possible.
However it is not always possible to avoid potentially breaking
changes.
Note also that SymPy 1.5 drops support for Python 3.4 and most
importantly will be the last release of SymPy that supports Python
2.7. This makes it especially important to try and avoid regressions
in this release so I hope that it gets as much pre-release testing as
possible.
Issues with the release should be reported on Github (make sure to
specify if the issue is a regression since 1.4):
