v2.2

Release Notes

Onboarding & Model Setup

• Introduced a deferred first-send model gate: missing-model setup now happens in-thread instead of on the welcome screen, preserving the pending prompt across refresh and auto-dispatching once a model is configured.
• Unified the onboarding provider selection into a single step covering Cloud, Account, and Local choices, replacing the previous separate illustrated paths.
• Utility model selection is now explicit — no longer silently synced to the main model — and defaults to each provider's utility model when available.
• OAuth account connections no longer auto-populate Main and Utility models; users are routed to model configuration to make an explicit choice.
• Fixed stale OAuth model provider appearing selected when the stored model slot points at a non-connected provider.
• Updated default main model to anthropic/claude-sonnet-5 across bundled config, Balance preset, and onboarding defaults.
• Refreshed Codex OAuth defaults: removed stale model metadata so connected accounts use upstream /models responses instead of the retired gpt-5.2-codex default; fallback model updated to gpt-5.5.

LLM Transport & Streaming

• Stabilized LiteLLM provider fallback: Responses endpoint failures now fall back to Chat Completions before any output is emitted, including when the Responses mock encounters real SSE streams.
• Streamed Chat Completions tool-call deltas are now preserved as structured function-call items, so fallback providers can still drive tools.
• Fixed streamed parallel tool extraction so nested tool_calls objects no longer prematurely end the stream before the parallel wrapper closes.

Chat & Memory

• Pruned deleted saved chats from sidebar state so stale in-memory contexts disappear after their chat files are removed.
• Normalized memory_load threshold and limit values from model calls before vector search, preventing numeric strings from reaching FAISS unchanged.
• Users are now notified when automatic chat renaming cannot reach the Utility Model, while the rename task remains best-effort.

Web UI

• Chat composer now supports Markdown-backed code blocks: typing a triple-backtick fence and pressing Enter creates a visual code block, serialized back to fenced Markdown on send.
• File browser action menus now render outside the scroll container with fixed positioning, fixing dropdown clipping.
• Message action button chrome is now non-selectable so copy/paste captures message text without toolbar labels.
• Settings secrets render as masked text inputs instead of browser password fields, avoiding password-manager prompts.
• What's New cards are disabled until new content is added; manual access remains available with an empty state.

Documentation

• Refreshed onboarding screenshots and first-run docs for the new welcome screen, in-chat model gate, and provider paths.
• Documented Docker host-gateway addressing for local model servers where container localhost does not reach host loopback.
• Clarified that the memory plugin is optional and removed memory-plugin assumptions from non-plugin documentation.
• Updated A0 Launcher download links to v1.1.
