Agent Zero v2.2 Release Notes

Browser Viewer & Streaming

Fixed URL intent routing so custom Agent Zero schemes are no longer misrouted to the browser handler
Replaced the 50 ms idle poll with a blocking frame read so live screencast delivery follows the producer cadence
Negotiated binary and slim screencast frames to avoid base64-in-JSON overhead and repeated metadata on every frame; clamped capture to subscriber viewport and DPR with lower streaming JPEG quality
WebUI binary-frame negotiation is disabled until Socket.IO properly reconstructs binary attachments; base64 fallback is preserved
Browser frames now use contain sizing during resize to stay proportional instead of stretching
Introduced a canvas/ImageBitmap rendering path for live frames with WebSocket streams attached as runtime screencast consumers, removing per-frame round trips
Hardened frame push completion so the WebSocket supervisor wakes correctly when the runtime frame task stops early; canvas backing store is no longer needlessly reallocated on every frame
Fixed viewer input (hover, click, wheel) after screencast stream restarts by notifying consumers on stream stop and preserving the active canvas as the input surface

Added configurable per-chat vs. shared tab scope with a maximum-tabs-per-chat cap exposed in Browser settings
Added BYOB (Bring Your Own Browser) host browser selection with config normalization, settings UI, and CLI-advertised inventory forwarding
BYOB browser inventory now refreshes while Browser Settings is open; added labels and guidance for Brave, Opera, Vivaldi, and Chromium-family browsers
Refined BYOB endpoint selection to automatic, advertised debug endpoints, or a validated custom endpoint with faster inventory refresh
Browser keyboard capture no longer prevents typing in chat composer or other editable fields

Skills are now loaded into chat history instead of being injected as scope-wide prompt pins; legacy active-skill prompt injection is disabled
Simplified relevant skill recall by searching the raw user message with structural matching (name terms, tag/trigger phrases, description phrases) instead of a stopword catalog
Removed legacy skill prompt cleanup code
Active-project AGENTS.md path-chain guidance is now loaded into the protocol area without duplicating root project instructions

Added built-in Orchestrator plugin (_orchestrator) with adapter status APIs, settings UI, per-agent skill references, and thumbnail asset
Added built-in Slash Commands plugin (_commands) with command storage, picker UI, bundled canonical command pack, and legacy migration
Added built-in Goal Management plugin (_goal) with per-chat goal storage, WebUI goal strip, /goal slash command, and agent-facing goal tools
Plugins declaring the external settings section are now exposed from the External Services settings page

Defaulted direct Venice chat provider to chat-completions transport
Local and broad OpenAI-compatible chat providers (LM Studio, llama.cpp, Ollama, Ollama Cloud, oMLX, vLLM, and other compatible) now default to chat-completions transport, since their Responses API implementations are often missing or unstable
Fixed Responses provider state after history compaction — stale provider-side context is cleared when automatic compression or manual compaction rewrites local history
Migrated saved Venice model config so Venice slots use chat completions with the Venice system prompt disabled
Fixed Codex OAuth request metadata and model slug handling for proxied Responses requests
Normalized Codex Responses input shape so empty continuation turns forward list-shaped input correctly

Shell-style local MCP command values (e.g. uvx workspace-mcp) are now properly parsed before spawning stdio clients; collapsed option/value argument lines are split correctly

Fixed PTY reset hangs by starting local shells in a new process session and escalating from SIGTERM to SIGKILL when a foreground command refuses to exit
Parallel code execution children now render as the proper code_exe log type in the WebUI
Fixed parallel child log typing to resolve tool-specific log objects for all child jobs, not just code_execution_tool
Parent-visible child logs are reused in direct parallel worker execution, preserving native badge types through execution

Startup vendor scripts now load with defer and Bootstrap is served locally, eliminating parser-blocking CDN requests on first mount
Fixed transient UI layering so toasts and tooltips appear above modals while confirmation dialogs stay on top
Cached component module imports are now properly awaited before appending deferred markup, preventing race conditions with Alpine bindings
Agent prompt now documents the split framework/task Python runtimes and the WebUI JSON API with CSRF token flow

Time Travel history is excluded from self-update user-data backups
Transient delete/rename races no longer surface as Time Travel snapshot errors for removed workspaces
Updated launcher README links to v1.2
Improved README with sharper positioning, scannable feature table, launcher-first install flow, and basic troubleshooting
