Changelog

What’s new.

This changelog lists what Wondermayank has added, fixed, improved and removed on ThunderStudy AI Mind Map, newest first and with dates. The latest update, on 3 October 2026, moved the backend to Cloudflare Pages, added search-engine and AI-assistant files and installable-app support, and rewrote the About, FAQ, Pricing, Performance and Changelog pages for the mind map maker.

Latest

Added

  • functions/api/generate.js and functions/api/youtube-transcript.js: the backend now runs as Cloudflare Pages Functions, with a health check at GET /api/generate
  • Server-side rate-limit backstop using Upstash Redis (8 maps a day and 30 a week per IP), switched on only when its keys are set
  • .dev.vars.example listing the environment variables, and a rewritten README.md
  • robots.txt and sitemap.xml, with AI crawlers (GPTBot, ClaudeBot, PerplexityBot, Google-Extended) allowed
  • llms.txt and llms-full.txt so AI assistants can understand the site and its presets
  • manifest.json with maskable icons (icons/icon-maskable-192.png, icons/icon-maskable-512.png) and app shortcuts, so the site can be installed
  • sw.js service worker: caches the app shell, the offline page and the presets, network-first for pages, cache-first for assets, and never caches the API
  • _headers (security headers, cache rules, noindex for offline and 404), _redirects (clean URLs) and _routes.json (Functions run only for /api/*)
  • .well-known/security.txt, ads.txt and humans.txt
  • IndexNow support: a key file in the site root and indexnow-submit.sh to notify search engines of new URLs
  • Pricing and Performance links, plus Presets, in the header and footer

Fixed

  • About, FAQ, Pricing, Performance, Changelog, Offline and 404 pages now describe the mind map maker, with wording left over from a different product removed
  • Page addresses, canonical links and sharing tags now use mindmap.thunderstudy.indevs.in and clean URLs without .html
  • A broken header link to a page that does not exist is gone from the navigation
  • The server API no longer depends on a file on disk for its limits, which cannot work on Cloudflare

Improved

  • The FAQ now has 16 answers covering cost, sources, Quick overview vs Deep dive, limits, saved maps, exports, PDF limits, privacy and offline use
  • The API now only accepts calls from this site
  • Every page links the web app manifest and registers the service worker

Removed

  • The Vercel-style api/ folder and the file-based rate limit
  • The unused web-app-manifest-192x192.png and web-app-manifest-512x512.png icons, leaving one icon set in /icons
