Changelog

New features, improvements and hotfixes for dev-nulll, by release.

What’s new in dev>nulll. The desktop builder stays free and open source; the paid plan adds always-on hosting and the features below. Newest releases first.

build 1.1 — Secure Hotfix — June 21, 2026

Security hardening release. Several vulnerabilities across the platform have been identified and closed. No user-facing features were changed; this release contains only security fixes.

We recommend all users on the Paid plan re-authenticate to ensure your session reflects the latest security state.

v1.0.0 — June 18, 2026

  • 1.0 — out of beta. Everything on the Pro plan is now live; no more “coming soon”.
  • Broadcasts & scheduled campaigns. Message everyone who uses your bot from the new Broadcasts tab — send now, at a set time, or every day.
  • Logs & version rollback. View your deployed bot’s live logs and roll back to any previous config in one click, from the new Server tab.
  • Plus everything from the 0.2.x line: log in without creating a bot, the Stars-invoice fix, and a pile of reliability & security hardening under the hood.

v0.2.5 — June 18, 2026

  • Log in without creating a bot. Signing in to Telegram no longer forces you to make a bot on the spot — log in to look around or manage your subscription first, and create a bot whenever you’re ready.

v0.2.4 — June 18, 2026

  • Fixed: the Stars subscription invoice wouldn’t open on Windows. It now launches straight in the Telegram app instead of a browser tab that didn’t hand off. Crypto payment links open the same way.

v0.2.3 — June 18, 2026

  • More resilient bots. A failure handling one message can no longer take a bot offline — each update is isolated, so your bot keeps running.
  • Hardening. Tighter safety limits on outbound HTTP requests and custom code blocks for bots running on the server.
  • Clearer errors. If a build can’t reach the Paid control-plane, the app now says so up front instead of failing silently on a button click.

v0.2.2 — June 18, 2026

Hotfix. Fixed a packaging issue in v0.2.0–v0.2.1 where the Pro features — signing in to your account, one-click deploy, analytics and revenue tracking — reported “control-plane not configured in this build”. Building and testing bots locally was never affected. Reinstall v0.2.2 from the download page to restore Pro.

v0.2.0 — June 2026

  • Revenue tracking. See how much your bots earn in Telegram Stars across every live bot — in the app’s Analytics tab and via /revenue in @devnulll_bot. We only count the earnings; the money is always yours and paid directly through Telegram. See Revenue tracking.
  • Accept Stars payments in your bots. Add Stars invoice and “payment received” blocks to charge your users and branch on a successful payment.
  • Mini App live publishing. Publish a bot’s Mini App over HTTPS and wire it to the menu button — no separate hosting.
  • Analytics. Track users, events and top commands for your deployed bots, with a local/deployed toggle.
  • Upload images from your computer. Use local images in messages, albums and Mini Apps — hosted for you over HTTPS.
  • Public API & incoming webhooks (free). Drive your bots from other services and manage them over a REST API. See API reference.
  • Per-bot isolation. Deployed bots now run in isolated containers with resource limits and automatic restart.
  • Streamlined editor: full autosave, a simpler toolbar, and a single place to manage your Pro plan.

v0.1.0 — June 2026

  • First public release.
  • Auto-BotFather. Create a Telegram bot in one click from inside the app.
  • Visual no-code builder. Build flows on a canvas from 37+ blocks.
  • Mini App designer with live preview.
  • Local testing and an offline sandbox to try your flow before going live.
  • One-click deploy to run your bot 24/7 on our servers (paid).
  • Custom code blocks and source export.
