Websockets 16.0, released in January 10, 2026, breaks CAT-SOOP. There are non-backwards compatible changes that prevent an instance from starting up. Until code can be updated to reflect the new changes, there should be a hard version requirement to prevent installing websockets >=16.0.

I can't replicate this on the current main branch (which seems to be working fine with websockets v16). I could imagine the lts-19 branch having trouble with it, but there I have websockets==12.0 in the requirements.txt.

Can you share some more info about how you're running this and, e.g., what kind of error message you're getting?

I had done the following:

Create new venv
pip install catsoop=19.0.6
try to start up catsoop instance (catsoop start)
error:RuntimeError: no running event loop
[start_catsoop.py 1624894] reporter!r (pid 1625672) died. restarting.
Traceback (most recent call last):

self.loop = asyncio.get_running_loop()

I also tried the above steps but with most recent catsoop. The requirement of websockets==12.0 prevents this issue. A forced upgrade to 16.0 reproduces this error, but there is only select reasons why that may be necessary. An extra note from my own usage: I was able to safely upgrade to 15.0.1 to satisfy additional dependencies for software used in conjunction with catsoop.

Sorry I think this is actually be a false alarm. It looks like this is only an issue when installing older versions of CAT-SOOP. The most recent version has the requirement you had mentioned, so there is no issue. I had done the following: 1. Create new venv 2. pip install catsoop=19.0.6 3. try to start up catsoop instance (catsoop start) 4. error:RuntimeError: no running event loop [start_catsoop.py 1624894] reporter!r (pid 1625672) died. restarting.
