On Saturday, November 9th, websockets 14.0 was released to PyPI which is incompatible with python-libjuju < 3.5.2.1. You will quickly encounter this version incompatibility if you’re using the juju and pytest-operator packages to run your charm integration tests as you will start to see several AttributeError’s raised instead of charms being deployed:

To avoid the issue, you will either need to bump the version of python-libjuju you’re using to the newly released 3.5.2.1 version that specifies an upper-bound for the version of websockets pulled from PyPI, or pin the version of websockets pulled to be less than 14.0 in your test requirements.
