re-inviting the same email still works when the wallet is at its limit * Wallets that already have more collaborators than their plan allows keep every existing member — only new invitations are blocked *** ## August 2026 — Performance & Consistency ### Improvements * Dashboard loads significantly faster: smarter query caching, deduplicated session checks, and an instant loading shell instead of a blank page * Redesigned dashboard widgets with a unified card style and period selector * Consistent page headers, tables, confirmation dialogs, and forms across the whole app * Visual refresh of the Contacts page and all forms * All CSV exports now share one hardened pipeline: consistently quoted, UTF-8 encoded output * Tables now clearly distinguish "still loading" from "failed to load" ### Infrastructure * Production moved to new hosting infrastructure with a fully automated build-and-deploy pipeline ### Documentation * Full documentation refresh — every page reviewed and corrected against the current app, plus a new Analytics page guide *** ## Late March 2026 — Security & Accuracy ### Security * Security audit completed: 26 fixes across authentication, payments, imports, and API routes ### Improvements * Dashboard and analytics now aggregate consistently in USD; USD values are captured during import and were backfilled for existing transactions * New **All Time** period option in transaction date filters * Transactions table shows the network beneath the wallet name * Top Contacts widget: aligned columns and USD amounts ### Fixes * Wallet filter chips no longer shrink at smaller viewport sizes * Latest Transactions widget sizing and typography refinements *** ## March 2026 — v1.0 Visual Polish & Quality ### Improvements * Comprehensive visual audit across all pages at 3 viewport sizes (1280x800, 1440x900, 1920x1080) * Migrated all hardcoded hex colors to Tailwind theme tokens across 200+ component files * Dashboard header updated with icon and subtitle to match page header pattern * Contacts toolbar responsive fix: icon-only buttons below lg breakpoint * Admin users table overflow handling for 12-column layout * Standardized form validation with inline error messages on sign-in and sign-up * Email verification pre-check before sign-in attempt * Cross-page consistency improvements for card styling and filter patterns ### Fixes * Fixed contacts toolbar wrapping at smaller viewports * Fixed hardcoded hex colors in modals, drawers, and overlay components * Fixed admin status badge colors for dark theme * Removed welcome notification on signup to enable proper empty state display * Fixed CSV export button using hardcoded hex colors *** ## February 10, 2026 — Production Release ### New * **Marketing Website**: Full landing page with Hero, Features, Pricing, FAQ, and Use Cases sections * **Email Verification**: New email verification flow for sign-ups * **USDC Support**: USDC token support for Ethereum wallet imports * **Documentation**: Help center at help.chainbook.app * **Error Monitoring**: Sentry integration with environment detection and source map uploads ### Improvements * Dark theme aligned with design prototype across dashboard, wallets, empty states, sidebar, and logo * Standardized responsive padding across all private route pages * New double-chevron logo replacing old 3D geometric design * Renamed "Wallet" domain concept to "Asset" across the entire application * Google Tag Manager restricted to production environment only * Dynamic robots.txt blocks crawlers on dev/stage, allows production * Etherscan API retry with exponential backoff for rate limits and server errors * Branch-filtered builds (main, dev, stage only) ### Fixes * Await SendGrid API calls to prevent silent email failures * Reduce email resend cooldown from 5 minutes to 1 minute * Fix invitation token expiry handling * Filter auth errors from Sentry and return proper 401 responses * Fetch emailVerified from database instead of cached session * Allow logged-in users to verify email via URL click * Fix worker crash: move dotenv and @sentry/node to production dependencies * Fix worker import errors for deleted wallets and duplicate transactions * Fix React version mismatch causing build failures *** ## February 3, 2026 ### Improvements * Fixed React version mismatch causing Vercel build failures * Improved build stability and deployment reliability ### Documentation * Launched Mintlify documentation at help.chainbook.app * Added changelog to track product updates *** ## How to read this changelog * **New** — Brand new features and capabilities * **Improvements** — Enhancements to existing features * **Fixes** — Bug fixes and resolved issues * **Documentation** — Updates to guides and documentation * **Security** — Security-related updates and patches This documentation is built and hosted on [Mintlify](https://mintlify.com), a developer documentation platform.
