I'm writing to let you know that CAT-SOOP v2019.9.5 (LTS) has been released and is now available via PyPI. This is a bugfix release that I believe resolves a long-standing issue that prevented a small fraction of students from logging in successfully without using Incognito mode or clearing cookies.
You can upgrade your installation via pip:
$ pip3 install --upgrade 'catsoop~=2019.9'
...or by cloning the repository and checking out the v2019.9-lts branch.
If you have any questions about the changes, or if you need help with the process of updating your catsoop install, please feel free to reach out!
