v2.14

# Agent Zero v2.14

## Highlights

- **Significantly faster startup and chat loading** — Embedding warm-up now overlaps with chat restoration and startup watchdogs, reducing median boot-to-first-token by ~27% and chat-switch latency by running model/profile refreshes independently of snapshot rendering.
- **Upgraded LiteLLM (1.104.0) and OpenAI SDK (2.54.0)** with an automatic startup migration for existing Docker instances, including installed-SDK HTTP test coverage.
- **Native LiteLLM routing for core providers** — Nebius, Venice chat, Z.AI/Coding, and OpenRouter embeddings now use LiteLLM's built-in integrations, simplifying provider configuration while preserving existing overrides.
- **Responses prompt caching fix for long conversations** — Completed Responses turns now retain masked extras at their original boundaries, preventing growing conversations from discarding cacheable prompt prefixes. A live test reached 99.3% cache hit rate at 131K input tokens.

## Browser & Performance

- Reduced browser startup and rendering overhead — avoids launching Chromium for empty tab listings, eliminates redundant load waits, and reuses native viewer display size. Local navigation medians improved from 474→83 ms, content reads from 82→19 ms.
- Simplified Browser quick settings to focus on preset, Host/Container, zoom, and extensions; moved extension management and Chromium settings pages into Browser config. Added annotation screenshots as an opt-in setting.
- Removed overlapping tooltips from Browser quick settings popover.

## Chat & Sidebar

- **Fixed disappearing chats** when Sidebar Folders was disabled and another plugin imported the folders store.
- **Fixed sidebar folder lag** during activity and focus updates by replacing repeated full-context scans with a shared parent-child index. Median activity updates dropped from ~67 ms to 15 ms.
- **Persisted sidebar Project, Status, and Last Activity filters** across reloads.
- Fixed chat activity timestamps not updating when continuing a chat, by writing to the context timestamp in the shared history writer.
- Revealed children of selected subagents at every delegation depth.
- Fixed chat naming to preserve manual names under "always" mode and validate custom names before marking them manual.
- Fixed pruning of just-saved chat contexts by re-checking disk before removal.

## Model & Preset Management

- **Reload model presets before the preset editor opens**, preventing stale drafts from deleting presets created in other tabs or via the API. Fixes #1928.
- Capped preset and agent profile selector menus to stay within the viewport.
- Detect Claude models across all providers (OpenRouter, Vertex AI, Bedrock, etc.) for thoughts-prompt adaptation, not just those with "anthropic" in the provider name.
- Restored full-response repeat checks for native tool calls, including commentary comparison.
- Added context window display controls and price currency selection with Frankfurter exchange-rate conversion and 24-hour caching.
- Enabled Venice and Agent Zero API cache routing; exposed `a0_prompt_cache_mode` for custom providers.

## OAuth & Codex

- Improved Codex reconnection flow — handles rejected refresh tokens with actionable toasts, offers Reconnect without manual disconnect, and displays device challenge codes in a copyable box with accessible feedback.
- Pinned Codex client version to 0.160.1.
- Added success feedback when copying OAuth device codes.

## Agent Execution

- **Direct subordinate delegation now runs through the child's own context task**, making child chats visible as Working/Paused and independently stoppable. Propagates caller cancellation while treating child-only Stop as recoverable.
- Terminal I/O no longer blocks shared event loops — uses nonblocking POSIX PTY reads and cooperative writes.
- Fixed native Windows TTY cleanup to avoid evaluating POSIX-only SIGKILL.
- Fixed SSH command truncation — uses `sendall` through `asyncio.to_thread` to deliver complete commands including large heredocs.
- Host Computer Use sessions now start automatically on the first action within the same tool call.

## Plugins & Configuration

- **Fixed user plugin precedence** — bundled values no longer overwrite community provider/profile definitions or subordinate profile settings during merges.
- Scheduler prompt editing now uses full-width resizable fields with an expanded modal view; supports optional `tasks.yaml` files alongside JSON.
- Added Paradee Heart as the default Local TTS voice alongside Kokoro, with lazy CPU ONNX synthesis and cached model assets.
- Single-folder downloads are now named after the folder instead of using a generic timestamped archive name.

## Infrastructure

- Raised security floors for aiohttp, anyio, urllib3, filelock, fsspec, and multidict.
- Seeded APT indexes only when absent, skipping refresh on normal container boots.
- Added Chat Completions reasoning fallback test coverage.
- Updated Launcher README links to v1.9.
