Release Notes

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.
