Done: https://pypi.org/project/emcee/3.1.5/

Please report back if there are any issues!

You can install the numpy 2.0.0 release candidate from pypi, but only for python>=3.9.

You need at least numpy 1.25.0: https://numpy.org/doc/1.25/release/1.25.0-notes.html#numpy-now-has-an-np-exceptions-namespace

There should be a workaround to support earlier versions. Will do a PR.

Hi team, I haven't looked into the details yet, but emcee v3.1.5 seems to conflict with numpy v1.24.4 (the highest numpy version under python 3.8). I get the following error message under the mentioned version:

AttributeError: module 'numpy' has no attribute 'exceptions'

Is there any possible fix (e.g. specifying emcee v3.1.5 to only require numpy >= 2, or do I have to just wait for numpy to officially release the new major version?

@dfm this should get another bug fix release, since emcee 3.1.5 unintentionally dropped support for a lot of numpy versions.
