## What's Changed
* fix(llm): detect Claude model identity in deployment_name too (#13443) to release v4.4 by @onyx-cherry-pick[bot] in https://github.com/onyx-dot-app/onyx/pull/13468
  * Fixes Claude 5 models (e.g. claude-opus-5) rejecting requests with "'temperature' is deprecated" when the model identity lives in a custom provider's deployment alias, and makes adaptive thinking reachable for those configs.
* fix(chat): explain empty attachments to the model instead of silent emptiness (#13446) to release v4.4 by @onyx-cherry-pick[bot] in https://github.com/onyx-dot-app/onyx/pull/13469
  * Image-only/scanned documents no longer appear to the model as silently empty files; adds still-processing/unavailable notices and stops the chat path from pre-empting the worker's plaintext cache.
* fix(tools): disabling web search puts open_url in indexed-only mode (#13442) to release v4.4 by @onyx-cherry-pick[bot] in https://github.com/onyx-dot-app/onyx/pull/13471
  * Turning off Web Search in chat now actually cuts off live web access; pasted links are still served from indexed documents.
* fix(auth): password auth kill switch for SSO cutover (#12887) to release v4.4 by @nmgarza5 in https://github.com/onyx-dot-app/onyx/pull/13473
