Release Notes

The headline of this release is Space Souls — give each Space its own AI persona with an avatar that follows you — plus support for the Antigravity provider and agent reliability fixes.

🪄 Space Souls

• Give each Space its own soul: a named AI persona you bind per Space and edit in a dedicated editor — you can even have AI draft one for you
• Summon a soul with an @-mention or a chip in chat, and see its avatar in the sidebar header and floating on the page, following whichever Space you're in

🔌 Antigravity provider

• Added the Antigravity provider, with a Terms-of-Service warning before you turn it on
• The FAQ now covers the Antigravity ACP adapter install steps

🐛 Fixes & platform

• The agent now pierces closed shadow roots, so pages like LinkedIn's new app shell are readable again
• The Loop Jobs panel backfills existing jobs, and event toasts auto-dismiss (and can be closed)
• Sturdier builds: retry the Firefox l10n clone/fetch with backoff, rebuilt the chat-sidebar WASM, and pinned the arm64 toolchain to a Visual Studio instance with ARM64 + ATL

This release lets NevoFlux run tasks on a schedule and chase goals on its own, tracked from a new Jobs panel, with richer loop controls, OS notifications when the agent needs you, and a shortcut to toggle the sidebar.

📅 Scheduled jobs & goals

• New schedule and goal skills: ask the agent to run a task at a set time or on a repeating schedule, or to keep working toward a goal until it's verified done
• A background scheduler runs these jobs even while you browse, with a jobs badge on the floating avatar that shows running, needs-you and done states
• OS notifications now fire when the agent needs your attention and the window isn't focused, so reminders reach you even when NevoFlux is in the background

🔁 Loop Jobs panel

• A new Loop Jobs panel (in the maximized sidebar) lists running and completed loops, each with per-iteration details and the final result
• Loop cards always offer a "View details" toggle and a pass/fail verify chip, plus a proposal card with an "Evolve now" button to refine what the loop does
• Four starter loop templates and a new /loop verify option to gate each iteration

🧭 Space- and folder-aware tabs

• When the agent lists tabs it now respects your active scope and reports each tab's folder and Space, so it acts on the right tabs in Zen-style workspaces
• Fixes so pinned-tab groups and the top window resolve correctly

⌨️ Shortcut & under the hood

• Ctrl+Shift+A toggles the agent sidebar
• The agent can run JavaScript inside a Canvas artifact (canvas_eval) to check its own work
• Resynced the browser patches with upstream Zen changes

This release brings a floating agent avatar you can drag anywhere, a sidebar that follows each site's Zen Boost, a headless agent you can run in Docker, and code-signed Windows builds.

👤 Floating agent avatar

• A draggable avatar you can drop anywhere on the page, with a click menu to restore, maximize or close it
• Status bubbles show when the agent is done or needs you, and minimizing now collapses the sidebar into the avatar (replacing the old sidebar-rail minimize)
• Theme-aware bubble and menu colors, viewport-clamped positioning, and a NevoFlux logo fallback when no identity avatar is set

🎨 Sidebar follows the website's appearance (Zen Boosts)

• The agent sidebar now honors Zen's Boosts: restyle a site with a Boost and the sidebar follows its per-site look — invert, contrast, font, zoom and tint
• Powered by a new pure theme-color engine with dark-palette accent indirection
• The right sidebar gap now matches the left, with readable text across light and dark themes

📝 Sidebar markdown upgrade

• Switched the sidebar renderer to pulldown-cmark with table support, and split boot code out of init.js for a cleaner, CSP-safe startup

🐳 Headless agent — run it in Docker

• The agent now ships as a headless service you can run in a container: the new nevoflux/agent image (with a docker-compose.yml) spawns a fresh headless browser per task and serves a task HTTP API — no desktop UI required
• Drive it your way — submit tasks over a small REST API (POST /tasks, then poll or stream results via SSE), or talk to it through an OpenAI-compatible /v1/chat/completions endpoint, MCP or ACP
• Isolation-first: run one disposable container per task for untrusted work, or a long-lived service for trusted flows, with per-task policy caps (shell / filesystem / upload, domain allowlist, wall-clock and token budgets)
• Watch a run live in your browser over noVNC, scrape Prometheus /metrics, and reuse one browser across a sequence of tasks with session mode
• The image pulls prebuilt multi-arch (amd64 / arm64) releases — no local compile — and comes with the GBrain knowledge base enabled

🔧 Post-update maintenance

• Bundled cross-platform cleanup scripts run after each update, plus a replace/keep dialog when bundled skills change so your own edits aren't overwritten
• Successful Pack installs are now reported to the website's install count

🔐 Signed Windows builds & fixes

• Code-signed Windows installer and portable zip for x64 and arm64 (Authenticode SHA-256, RFC3161 timestamped)
• Extension menu-bar injection now probes both browser-menubar filenames, and agent state resets cleanly on daemon disconnect
• skill-creator's record & replay now compiles recordings into run_flow packages

A small stability release that makes the knowledge base work reliably in installed builds and keeps slow agent tools from timing out.

🧠 Reliable knowledge base in every build

• The agent's ONNX Runtime — the engine behind the knowledge base's embeddings introduced in 0.3.7 — is now bundled in every release for Windows, Linux and macOS (including universal builds) and refreshed when the in-app agent updates, so semantic search works in installed builds, not just in development

🐛 Fixes

• Raised the Claude agent's MCP tool-call timeout to 5 minutes (above the knowledge base's own 120-second limit), so a slow tool returns its real result or error instead of being cut off early by a timeout that looked like success

The headline of this release is Record & Replay — show NevoFlux a workflow in the browser once and turn it into a reusable skill — plus one-click Pack installs straight from a link.

🎬 Record & Replay

• Demonstrate a task instead of describing it: a passive recorder watches your real in-page actions and navigation (it never blocks you) while the agent writes an ordered, lossless trace
• Agent-orchestrated with new start_recording / stop_recording tools — the agent arms the recorder on the active tab, you perform the workflow, then it stops and reads the recording
• The skill-creator turns that demonstration into a reusable skill: values you confirm become placeholders, secrets are never baked in, and durable role + name selectors are carried over so the skill relocates elements live and survives page changes
• Browser use scope for now (in-page interactions plus navigation), with a new Record & Replay guide for skill authors

📦 One-click Pack install from a link

• Open a Pack install link and get an inspect → preview → confirm → install flow right in the browser, with live progress — no trip through Settings
• GitHub-only sources, with install / update / reinstall decided for you

🐛 Fixes & platform

• Windows: the agent no longer hangs on Ctrl+C shutdown
• Fixed the Linux AppImage launcher name and taskbar icon (zen → nevoflux)
• Skills: list fields such as allowed_tools now accept either a single value or a list

A big platform release: NevoFlux catches up to Zen Browser on Firefox 151, bringing Boosts and Space Routing, alongside Canvas and knowledge-base improvements.

⬆️ Synced with upstream Zen Browser (Firefox 151)

• Jumped from Firefox 149 to 151, picking up the latest upstream Zen features and fixes
• Boosts — restyle any website to your taste: adjust element size and text case, tweak color contrast, brightness and saturation, invert, or drop in your own CSS — then save and reuse them per site
• Space Routing — send matching sites to the Space you choose, so links open where they belong
• Plus upstream tab, workspace, split-view and window-sync fixes and polish

🧠 Knowledge base (Brain)

• Upgraded the embedding engine to fastembed 5 (ONNX Runtime 1.24.2) with dynamic loading, for faster and more accurate semantic search across your saved pages

🎨 Canvas

• Export an artifact's full HTML content to PNG, not just the visible viewport
• Large artifacts now persist reliably — the content store cap went from 500 KB to 50 MB, so files over 1 MB save without being dropped

🐛 Fixes & stability

• More reliable Pack install: progress now streams (no more 30-second bridge timeout) and a watchdog keeps the dialog from hanging if the stream stops
• Sidebar shows an optimistic "Start Setup" that reconciles with the authoritative status
• Softened harsh white-out flash transitions in the video skill's templates, with a new linter rule to catch them
• Steadier Windows native builds

A focused release that adds Packs management, with Windows build and stability fixes.

📦 Packs

• New Packs management section in Settings
• Install Packs directly from GitHub sources, with an inspect → preview → confirm flow
• A pack development reference guide for authors

🐛 Fixes

• Restored missing chrome resource URLs after the workspaces → spaces sync
• More reliable pack-install dialog — its auto-close timer now tracks the correct modal

🛠️ Build & platform

• Re-enabled WebRTC on native Windows builds
• Steadier Windows builds: capped native compile parallelism to avoid clang out-of-memory, de-hung the mozmake setup in CI, and trimmed cruft from the source tarball

🧠 Knowledge Base (Brain)

• A built-in personal knowledge base (your "second brain") powered by GBrain, an AI-agent memory system that synthesizes cited answers across your saved pages and auto-builds a knowledge graph — not just keyword search
• New nevoflux://brain browse page and install wizard, save-to-knowledge-base from any page, shareable .nbrain packs (create, manage, import), and a gbrain runtime with status and restart/update controls
• Five /brain skills work together:
  • brain — the hub: entry point and shared conventions that route to the four skills below
  • brain-capture — save and ingest notes, web pages, PDFs, Office and ebooks, video subtitles and images, with optional web enrichment
  • brain-recall — look up saved pages, recall facts, see what is notable or recent, and follow links and backlinks
  • brain-think — synthesize: multi-hop cited answers, who-knows-about routing, trends, concept maps and prediction calibration
  • brain-care — health and recovery: diagnostics, sync, find contradictions and orphans, and restore deletes or earlier versions

🔁 Iterative tasks (/loop skill)

• Run a prompt or skill on a loop, with sticky loop cards and per-iteration progress
• A /loop slash command and a DOM watcher for state-triggered iterations

🎬 AI video generation (/video skill)

• Generate videos on the Canvas with a new render pipeline (nevoflux://render): deterministic frame capture, progress cards and cancellation
• A library of HTML templates and components — captions, lower-thirds, transitions, data charts and 3D reveals — plus TTS and Three.js workflows
• A composition linter that catches issues before rendering

🤖 Stronger browser automation

• Rich-text and contentEditable editing (paste and fillRichText), file uploads, element probing and stable CSS selectors
• Shadow DOM editor support and smarter tab activation and navigation

🎨 Canvas sharing and tools

• Share and import canvases (nevoflux://import) with redesigned dialogs and one-click copy
• Pin artifacts to My Canvas, and manage custom Canvas Tools from settings

🧩 Platform

• An EventBus with notification toasts and tab-discard recovery; the NevoFlux Agent is now a built-in system add-on enabled on first launch

⬆️ Synced with upstream Zen Browser (Firefox 147)

• Brings Zen features and fixes: workspaces, split view, live folders, essentials, window sync, drag-and-drop improvements, macOS native popovers, and session backup and restore

A maintenance release focused on extension distribution and Windows upgrades.
