Hi,

I am having trouble running 2.3.0:

$ roundup-server --help
...
File "/path/to/virtualenvs/roundup/lib/python3.11/site-packages/roundup/mailer.py", line 24, in <module>
    from roundup import __version__
ImportError: cannot import name '__version__' from 'roundup' (/path/to/virtualenvs/roundup/lib/python3.11/site-packages/roundup/__init__.py)


Adding this to the mentioned __init__.py file fixes the problem:

__version__ = '2.3.0'


It seems that nobody is actually using this software - otherwise, I can't imagine how this problem could have slipped through the release process.
