What's New — October 1 to October 31, 2026

A month of making Revel ready for Europe's paperwork. The EU compliance package adapts ticketing and invoicing to each country's fiscal rules, and attendee invoices are now EN 16931 e-invoices with embedded Factur-X / ZUGFeRD data. The engine behind them is euinvoice, which we've released as an open-source Python library. Organizations can also run Revel on their own domain with their own brand colors. New organizers land on a launchpad that walks them to their first published event. And thanks to CodeRabbit, Revel is more secure than it was a month ago.

🇪🇺 EU Compliance & E-invoicing

  • Country-aware compliance. Revel now knows which features a country's law makes non-compliant, and blocks only that feature, only for the sales the law reaches, and only from the date it applies. Online card payment is refused for paid tickets at events held in Italy, where offline, bank-transfer and at-the-door sales keep working. Attendee invoices are turned off where a national real-time invoicing system applies (for example Croatia, Portugal and Romania, Basque TicketBAI, and Spain's Verifactu from 2027). Refusals name the country in your language, and the UI disables a blocked option up front (compliance capabilities on organization and event responses).
  • Organizer notices flag duties that stay yours, such as cash-register rules in Austria and Denmark, Poland's fiscal register for some admission types, and a heads-up before the 2027 Spanish change. They inform you without blocking anything.
  • Every ticket carries the fiscal basics. Ticket PDFs and Apple / Google Wallet passes show the organizer's legal name and VAT ID (or tax number), a gap-free ticket number (SERIES-000123), the issue time, the price or "Free", and a "not a tax invoice" notice.
  • Skipped fiscal documents. When a country rule means Revel must not issue an invoice or credit note, it's recorded so you can issue it from your own system. Owners get a filterable list with a resolve action for your external reference, a "Documents to issue yourself" sheet in the revenue report, and a daily digest.
  • EN 16931 e-invoices. Attendee invoices and credit notes now carry everything structured e-invoicing needs:
  • structured postal addresses for organizations, billing profiles and business buyers, with the country prefilled from the VAT ID;
  • a VAT category per line with legal exemption reasons for 0% VAT, which tiers inherit from an organization default;
  • the supply date and the payment method;
  • EN 16931 totals that preserve the charged amount to the cent.
  • Factur-X / ZUGFeRD PDFs. Compliant invoices and credit notes are issued as PDF/A-3 with the machine-readable CII XML embedded. Any accounting system that reads Factur-X picks them up without retyping. Every generated document is validated against the official CEN rules in CI, and the feature has a site-wide switch (einvoice_facturx_enabled).
  • Small-business organizers (German Kleinunternehmer, Austrian Kleinunternehmerregelung) can now turn on attendee invoicing. Every line is VAT-exempt with the statutory note, and tickets show the tax number when there's no VAT ID.
  • Credit notes now mirror the original invoice's lines exactly, and partial refunds are prorated so they add up to the invoiced amount to the cent. Revenue reports split plain 0% sales from reverse-charge ones.

📦 euinvoice: our e-invoicing engine, now open source

Everything above runs on euinvoice, a small, typed, MIT-licensed Python library we built and published on PyPI (pip install euinvoice):

  • one EN 16931 model, written out as UBL or CII;
  • Peppol BIS 3.0, XRechnung 3.0, Factur-X / ZUGFeRD (generate and embed in PDF/A-3), and Italian FatturaPA;
  • validation against the official XSD and Schematron rule sets (CEN, Peppol, KoSIT), not a reimplementation;
  • framework-free: bytes in, bytes out, with no Django, network or file-system access in the core.

It's pre-1.0 (currently 0.2.1). If you work with European e-invoices in Python, try it, file issues and send PRs. Docs: letsrevel.github.io/euinvoice.

🎨 Your Brand, Your Domain

  • Custom domains (white-label). An organization can serve its public site on its own domain, for example events.example.org:
  • the organization page becomes the home page, with your name, logo and colors in the header and footer, and a small "Powered by Revel" line;
  • sign-up, RSVPs, paid checkout, seat holds, memberships and the attendee dashboard all work end to end on the domain;
  • attendee emails link to it, and old Revel URLs of your pages redirect there.

Owners connect a hostname from Admin → Custom domain, see the exact DNS records to add, get hints for the usual DNS mistakes, and watch the live status. The feature is enabled per organization on request. - Brand colors. Pick a primary and an optional accent color, and organization, event, series, membership and embed pages use them in light and dark mode. Revel adjusts lightness where needed so text stays readable (WCAG contrast), and the settings show a live preview. - Your logo and colors also appear on wallet passes, ticket PDFs and the footer of organization emails.

🚀 Getting Started & Running Your Org

  • Organization launchpad. Right after creating an organization, owners land on a welcome page with two next steps side by side: create your first event, and connect Stripe to get paid. A setup card on the dashboard tracks the five steps until your first event is live. Creating an organization now asks only for a name and a contact email.
  • Redesigned admin dashboard. A "Next up" panel shows the next or current event with attendance and quick links to check-in and the guest list. "Needs attention" counts pending requests, drafts and missing billing details. The admin tabs are now a grouped sidebar.
  • Redesigned event editor. The title and status sit on top, with tabs right below. Details are split into clear sections with a live summary rail and a single Save button. New events start by asking "RSVP or Tickets?". Descriptions can be edited full-screen.
  • Publish and share. Drafts show "Ready to go live?" with a Publish button. Right after publishing you get the link to copy plus WhatsApp, Telegram and email share buttons.
  • Connect Stripe without losing your place. Choosing online payment on a paid tier lets owners connect Stripe and come straight back to the tier they were building.
  • Setup nudges. Owners of organizations that stall (a private page, forgotten drafts, no events yet) get a few gentle, capped reminders. You can opt out of them like any other notification.

🎟️ Events & Tickets

  • A tier's availability now reflects the event's capacity as well: a 40-ticket tier on an event capped at 30 shows 30, and the tier form warns when a tier exceeds the cap.
  • Free tickets can be self-cancelled. New free tiers let attendees cancel by default, which frees the spot for someone else, and the cancel dialog no longer talks about refunds.
  • Card disputes are tracked per payment. Staff with ticket permissions are notified when a dispute opens, with the amount, reason and evidence deadline, and again when it closes.
  • Checkout prefills the ticket-holder name when there's a single ticket. Claimed invitation links now move you straight to the next step instead of asking you to claim again.
  • Cover art shows uncropped at 16:9, and the "Part of a series" card shows the series logo and description.

🔔 Notifications & Comms

  • Organizer alerts have their own settings. Ticket sold, cancelled and refunded, and series pass sold and cancelled, are now separate staff notification types. Your own receipts stay "Always on", and settings explain which emails can't be turned off.
  • "Unsubscribe" in your mail app now reaches Revel, and turns off only that one notification type. Receipts and account emails can't be silenced by accident.
  • Emails, notification dates and Apple Wallet passes now follow each recipient's language, for example „Montag, 26. Oktober 2026, 13:20 CET". Guest confirmations are sent in the language the guest used on the site.

🌍 Self-hosting & Infrastructure

  • Custom domains for self-hosters. The infra stack ships a Caddy on-demand TLS catch-all backed by GET /api/tls/ask, and a tenant mode for the frontend. Setup is documented in the white-label operator guide.
  • Bot check on registration with Cloudflare Turnstile (TURNSTILE_SITE_KEY / TURNSTILE_SECRET_KEY). It's off by default, and sign-ups stay open if Cloudflare is unreachable.
  • PUBLIC_HIDE_SOLUTIONS_FOOTER hides the marketing footer links on self-hosted instances, and a configurable support email (support_email on /version) feeds the "contact us" buttons.
  • Grafana moves to 13.2, and the setup wizard covers the new environment variables.
  • /llms.txt gives AI assistants a plain-text summary of Revel, and robots.txt now lets AI search assistants in while keeping training crawlers off event and organization pages.

🛡️ Security, and a thank-you to CodeRabbit

A big thank you to CodeRabbit for their open-source security pledge, and for offering free deep security scans to open-source projects. Revel is open source end to end, and their scan, alongside the CodeRabbit reviews that already check every pull request we open, helped us make the platform more secure across the backend, the frontend and our infrastructure. If you maintain an open-source project, take them up on it.

This month also brought the usual upkeep. Outbound connections stopped trusting a certificate authority that was distrusted in October, and dependencies were patched as advisories were published.
