Changelog — NodeBOM

v1.1.0

April 8, 2026 Feature Release

New — Team Plan

Team Hub — workspace cards with live member avatars, lock status badges, and inline rename
Per-session auth tokens — replace leaked client IDs for all REST and WebSocket operations
Lock enforcement — REST mutation endpoints (save, delete, rename) require holding the workspace lock
Admin panel — audit log, backup snapshots with one-click download, and automatic backup rotation
Workspace export — portable JSON bundle for server migration or offline archival
Onboarding overlay — first-time guide walks new team members through extract, sync, and lock workflow
Server-side attribution — display names resolved from authenticated session, not client headers
Graceful cloud-outage tolerance with 1-hour grace period before seat revocation

New — Desktop

Revision History — automatic change tracking with structured diffs, timeline view, summaries, labels, and one-click restore with preview
Part Library (Premium) — save reusable parts once and insert them into any future project. Bulk save from BOM, inline editing, search, sort, and export
Delete individual workspaces — remove a single workspace and its revision history without clearing everything
Offline mode — machine-bound licensing with hardware fingerprint, all frontend assets bundled locally, per-feature allow/deny flags
Production authentication — migrated to production Clerk instance with custom domain for faster, more reliable sign-in
Version tracking — your app version is reported to your account so the website can notify you when a newer release is available
License status card — sidebar card showing your current plan and license state at a glance

Improved

Sidebar redesign — larger click targets, better hover/press feedback, and reorganized layout separating tools from account features
Dark mode overhaul — semantic theme system with CSS custom properties; over 250 elements fixed across the entire UI
Account page — shows your actual app version with update notices, and correctly displays your plan tier
Stripe Checkout now pre-fills the email from your signed-in account
Part Library updates immediately after saving parts from BOM

Security

Nonce-based desktop sign-in with XSS token guard
SSRF protection on local AI (Ollama) URLs
Vault clearing on startup to prevent stale session data
Rate limiting on WebSocket messages with automatic disconnect
Workspace saves scoped by user to prevent cross-user overwrites
Database writes serialized to prevent concurrent write corruption

Fixed

License verification no longer blanks user identity, preventing workspace data from becoming invisible
Desktop sign-in now correctly redirects back to complete authentication instead of the homepage
New accounts always get a subscription record created on first sign-in
Imported workspaces now get an initial revision snapshot so history is complete from the start

v1.0.3

v1.0

March 29, 2026 Production Release

Added

Production-ready single-file installer — NodeBOM now ships as a standalone .exe with no Python or dependencies required
Stripe payment integration — Individual plan checkout with monthly and annual billing options via Stripe Checkout
Automatic account provisioning — signing up creates your profile and free subscription instantly, no manual setup needed
Google sign-in via Clerk authentication in production mode

v0.9.1

Brand & UI

Added

New "Precision Engineering" color palette across the desktop app — pine green primary, steel blue accents, copper warnings, warm neutrals replacing default slate/blue
Two-tier font system — Outfit for UI chrome, IBM Plex Sans for data-heavy tables, IBM Plex Mono for monospace elements
Dark mode contrast improvements across all data tables, inputs, and interactive panels in the desktop app

Improved

Splash screen and system tray icon updated to match the new pine green brand colors

v0.9.0

Nexar & Sourcing

Added

Nexar (Octopart) part lookup integration — BYOK setup in Settings lets users search 1,000+ distributors for live pricing, manufacturer data, and availability by manufacturer part number. Free tier: 100 parts/month, no AI credits required
Nexar results render inline in the Supply Chain column with Apply, Expand, and Dismiss actions — one-click to populate Vendor, VPN, and Unit Cost
Integrations section in Settings modal with Nexar Client ID / Secret management, validation, and monthly usage tracking
Onshape API key management added to Settings — configure, save, and clear keys without opening the extraction modal
AI COTS confidence review system — matches ≥70% are auto-applied, lower-confidence results require manual review with Apply/Dismiss actions
Octopart attribution on all Nexar result cards per Nexar API Terms of Use

Improved

AI COTS matching now recognizes electronic components and manufacturer part numbers (MPNs) — previously misclassified as custom fabrication
AI COTS prompt upgraded to cover both mechanical and electronic sourcing, with explicit MPN recognition and electronic supplier examples
COTS pre-filter inverted — all parts are now sent to AI by default instead of only matching a narrow mechanical keyword list. Only obvious assembly containers are skipped
Renamed "Match COTS" to "AI COTS" throughout the UI to distinguish AI-based matching from direct Nexar lookups

v0.8.1

Accessibility & Sharing

Added

WCAG 2.2 Level AA accessibility improvements across both the website and desktop app — skip-to-content links, ARIA landmarks, dialog roles, focus-visible indicators, and live region announcements
Accessibility settings panel in desktop app — dedicated Settings button in the sidebar with toggles for High Contrast, Reduce Motion, and Large Text modes (persisted in localStorage)
Accessibility floating panel on all website pages — FAB button with the same three toggles, Escape-to-close, and outside-click dismiss
Accessibility Statement page on the website via Termly embed
Project Export/Import (.nbom) — export workspaces, price tracker, inventory, and thumbnails as a single shareable JSON file; import on another machine with automatic duplicate detection
Export Project (.nbom) option added to Inventory Tracker, Price Tracker, and BOM Compare export dropdowns
Return Policy page on the website with footer links on all pages
Backend workspace limit enforcement — SQLite COUNT checks prevent exceeding the plan limit (1 for anonymous, 3 for individual)

Improved

Toolbar spacing increased — status badges and action buttons in the top bar are no longer crowded together
Inventory Tracker header font size and icon normalized to match Price Tracker and BOM Compare
Ollama URL handling standardized across all code paths — consistent .strip().rstrip('/') normalization in the backend, AI router, and model fetcher
AI Providers button icon changed from gear to lightbulb to distinguish it from the new Settings button
Billing inquiries now route to [email protected] instead of the business inbox
All website modals and interactive elements now include proper aria-expanded, aria-label, and role attributes
Accessibility toggle switches use fixed pixel sizing so they render correctly regardless of Large Text mode
Theme slider recalculates position after toggling Large Text to prevent misalignment

Fixed

Importing the same .nbom file twice no longer creates duplicate workspaces — fingerprinting based on assembly name, part count, and sorted part names
Workspace limit could be bypassed by creating workspaces directly through the API without frontend checks
Ollama remote URL field accepted values without http:// prefix, causing silent connection failures — now validated on save
Ollama local provider incorrectly appended user-entered URL instead of always using localhost:11434
AI router did not guard against empty model selection, producing cryptic LiteLLM errors

v0.8.0

AI & Multi-User

Added

AI Cost Optimizer for Price Tracker — analyzes your price list for bulk pricing opportunities, overpriced items, and procurement savings (4 credits, Gemini Pro)
AI Change Impact for BOM Compare — assesses engineering change risks, cost impact, and material changes between revisions (2 credits, Gemini Flash)
Cost flags on Price Tracker items — AI findings are displayed inline on each flagged row with type badges, savings estimates, and dismiss buttons
Context-aware AI FAB menu — the floating action button now shows only relevant tools for the active view (BOM tools on assembly, Cost Optimizer on Price Tracker, Change Impact on BOM Compare)
Per-user data isolation — all localStorage data and SQLite workspaces are scoped to the signed-in account so multiple users on the same machine never see each other's AI keys, workspaces, inventory, or reports
One-time data migration on first sign-in — existing unscoped data is automatically claimed by the first user who signs in after the update
Credit confirmation dialog for all AI tools — new tools go through the same cost preview and confirmation flow as existing operations

Improved

AI FAB persists across standard, management, Price Tracker, and BOM Compare views (hidden only on Inventory Tracker)
Toast notifications shift up when the AI menu is open to prevent overlap
BOM Compare tab now has the same bounce animation as Inventory and Price Tracker tabs
Cloud AI timeout increased to 120 seconds for reasoning-model operations (Gemini Pro)
Broadened cloud server exception handling to catch all LLM provider errors and properly refund credits on failure

Fixed

AI FAB disappearing after switching away from Inventory Tracker and back to other views
Cloud AI errors returning non-JSON responses that caused silent frontend failures
Frontend fetch calls for new AI tools now include a 150-second abort timeout to prevent indefinite hangs

v0.7.0
