v4.4.0
The big 4.4.0 rollup — the native macOS app, group chat, Flow view, multi-engine support, page annotations, and a deep rendering-performance pass. 217 changelog entries since the last release; highlights below.
Native macOS app
- A real Cocoa/WKWebView app (not a browser launcher), shipped as a signed, notarized DMG with Sparkle auto-update, native menu bar, ⌘Q/⌘R/zoom, and window-frame persistence.
- Homebrew and DMG install paths alongside the curl installer.
Performance (this release's focus)
- Opaque WKWebView — the app's web view was transparent, forcing WebKit to blend the whole page every frame; making it opaque restores the fast render path (fixes app-only scroll/typing/idle jank).
- Native composer sizing via CSS
field-sizing— removes a per-keystroke forced reflow. - Live-session icons pulse via GPU-compositable
transforminstead of animatedfilter: drop-shadow(was repainting every frame). - Debounced conversation-search re-render; gzip + conversation-metadata cache; conditional (ETag/304) session fetches.
- New footer frame-health monitor for spotting jank without devtools.
Group chat
- Orchestrator + @mentions, active-coordination highlight and bottom-left pill, per-chat enable/disable, wake-status, and an active-work panel.
Flow view
- A spatial canvas for sessions: nodes, range selection, session drafts, zoom, expand/collapse.
Multi-engine
- Antigravity (context + per-turn token usage, WIP indication), Codex, and Gemini support; orchestration-engine spawn and spawn defaults; subagent visibility.
Annotations & sharing
- Page annotations, an annotation bookmarklet, annotate-to-new-session, and a UX-queue engine.
Sidebar & sessions
- File viewer + files panel + file search, row pinning, reorder animation, archived-by-project toggle, session-layout persistence, inline template gallery, TTS word highlighting, live context from
/context.
…plus a large batch of fixes across layout, titles, CI, and engine handling.
