0.20.x adds gemma4 architecture and tools support. Chart 11.x+ took ownership of REDIS_URL injection from websocket.url, so use websocket.existingSecret instead of duplicate extraEnvVars overrides which were causing strategic-merge-patch failures on upgrade. Disable Ollama cloud features.

There was a problem hiding this comment.
I think backward compatibility with the database is what matters most, apart from ensuring that Knowledge and Filters still work in the newer version.

I did another upgrade test and it went cleanly this time, no issues with helm (unclear why it complained about the REDIS_URL last time). The filters and knowledge still worked (during testing yesterday and today). |

Backward compatibility
The chart upgrade did not work so I did a helm uninstall of open-webui (but kept the db in CNPG). I think it's related to the
REDIS_URLenv / secret.Testing
See backward compatibility for more info. I had to helm uninstall then make install-chat on dev02. Ollama 0.20.6 runs and gemma4 models load a run in Chat using same Open Web UI settings as gpt-oss.
Note for reviewers
Let me know your thoughts on backward compatibility. I could look into this more but we have just been starting fresh with Chat the last couple upgrade cycles.
