v0.3.67 Latest

Jul 26, 2026

featClean run exit with finish detection. arcana run emits a done signal on completion — foreground use with full log capture via | tee. No background hacks.
feat--timeout flag. Bound session duration on arcana run. Defaults to 120s — stops runaway sessions for CI, benchmarks, one-shot automation.
featBare model-name lookup. Names without a provider prefix (deepseek-v4-flash vs provider/model) resolve across all configured providers.

featDaemon respects OS signals. SIGTERM/SIGINT handled gracefully — clean shutdown, no orphaned processes.
featCross-directory daemon management. arcana daemon status / stop work from any working directory.
fixSilent TUI auto-spawn. Daemon auto-spawn no longer leaks stdout/stderr into the parent terminal.

Jul 26, 2026

featTUI auto-connects to daemon. Detects a running daemon, auto-spawns one if missing, falls back to Worker mode. No manual management.
featDaemon lifecycle. Lock file, isolated error handling, detached spawn, /health endpoint, arcana daemon status|stop.
feat/loop standalone. Research loop works without /goal, in TUI and CLI. Native /loop hub in run.ts for headless use.
fixNo more double body rendering in spine entries. Overlapping Show conditions resolved.
fixClean slash-command input. Plain-text lines stripped; multi-slash (/foo /bar) rejected.

Jul 22–26, 2026

featBrowser automation via MCP. agent-browser for CDP-based control — 29 tools for navigation, screenshots, forms, JS exec. Docs at /docs/browser-automation.
featOllama local models. Works with locally running Ollama instances. Models auto-discovered in the picker.
featSubagent spine entries — clickable. Toggle open to reveal child session messages inline; live progress while running.
featSmart JSON formatting. Generic tool output auto-rendered as tables or key-value pairs. Todo JSON gets interactive checkboxes + braille spinner.
featViewport culling + scroll-to-bottom. Large spines use virtual scrolling; a scroll-to-bottom button appears when scrolled up.
featSession metrics bar. Real-time token usage and cost below the input prompt.
fix/new creates sessions properly instead of just clearing the screen.
fixNo more "Tool did not finish" false errors. Pending tools no longer show as failed when the agent moves on.
fixWindows db crash fixed. Graceful message instead of sqlite3 crash in interactive mode.

Jun–Jul 2026

featOAuth device-code login. /connect lets free users sign in via device-code flow — visit a URL, enter a code, account bound.
featArcana error taxonomy. Structured, readable codes replace generic failures: ARC_AUTH_INVALID, ARC_CREDITS_EXHAUSTED, ARC_RATE_LIMITED — each with next steps.
featAI image generation. Generate images directly from chat, backed by configured providers.
featFree-tier foundations. Session management, quota tracking, turn budgets, free-tier model discovery.
featResearch workflows engine. Autonomous research loops with CLI commands, store integration, agent prompt wiring.
featTUI session performance. Sessions no longer remount on switch; spine entries cached. Dramatic render-time reduction for large histories.
featInstant Enter. Enter feels instant — all slash commands fire on single press.
fixProxy TLS stability. Primary domain proxy-arcana.otnelhq.com reliable; workers.dev fallback.
fixOAuth error handling. Device-code URL opened server-side; console login tolerates nullish payloads.
