Agent Zero v2.2 makes model setup explicit
Agent Zero v2.2 makes model setup explicit in-thread, removes silent OAuth
model auto-population, sets the default main model to
anthropic/claude-sonnet-5, sets the Codex fallback to gpt-5.5, and fixes
LiteLLM/streaming fallback paths. Channel: tagged-release. Operator consequence:
model defaults keep moving; pin models if cost or behavior must stay stable.
