Release 2023.8.0 of pretix

26. Sept. 2023

We're back to monthly releases after our short yearly summer break! Today, we are releasing pretix 2023.8.0. This includes new capabilities for our discounts system, improvements to scheduled emails, and a lot more! Big thanks go out to Alain, Ash So, Aufa Fadhlurohman, Ed Bennett, Felix Freiberger, Felix Hartnagel, Kian Cross, Mahdia Aliyy, Maurice Kaag, Michael, Patrizia Cotza, Rob, Ronan Le Meillat, Rubén Vargas, and Tuomas Savela who contributed to this release. ❤️

pretix 2023.8.0 is now available for installation via pip. The new Docker images will appear on Docker Hub over the next few hours. All customers of pretix Hosted are already using the new version and do not need to take any action.

Discounts: Buy X get Y free

In pretix 4.10, we introduced automated discounts based on cart content. For example, you can configure a group discount that automatically reduces all ticket prices by a certain percentage.

We are now taking this one step further by allowing the discount to apply to a different set of products than the products of the group. This allows us to support new scenarios, such as a common one in some industries: If a booking is made e.g. for a school class, one teacher gets in for free for every 10 paid student tickets. Similar scenarios are found in the tourism industry with a bus driver getting in for free with a certain number of tickets etc.

New internal locking mechanism

This release brings a significant, although invisible, change to how pretix works internally. One of the core features of every ticketing system is handling scarcity: Only a certain number of tickets is available in total, every seat is only available once, every voucher can only be used a limited number of times, etc.

To ensure that we do not e.g. sell a seat twice, pretix internally needs to use locking to make sure no two customers can submit a purchase request for the same seat at the exact same time. As a result of a multi-year effort, we have now rolled out a new approach to locking across pretix.

The new approach is more correct than the old one, with the main improvement being increased performance. The exact numbers depend on lots of factors including the server setup and the specific configuration of the event, but in our benchmarks, pretix can now handle significantly more orders within one minute for a specific event, without an error message being shown to a single user.

Smaller changes and bugfixes

Ticket shop and widget

  • You can now select Indonesian as a language option.

  • The invoice address form now pre-selects "individual" or "company/organization" automatically based on the more common choice for the given event and organizer.

  • During voucher redemption, the event title will now be shown in a headline in case it is not part of the site header already.

  • Bank transfer: If you allow your customers to send the invoice directly to the accounting department during checkout, this is now also possible after checkout on the order confirmation page, as long as the payment is pending.

  • Widget: The widget now allows different versions of Vue.js running on the same page.
