Release 4.2.0 of pretix

Today, we are releasing pretix 4.2.0. Summer is always a special time of the year – a mix of vacations, busy day-to-day work, and some quiet time to work on long-term improvements change the structure of work that is happening. Like in previous years, we've therefore skipped one monthly release. Today's release is also mostly a maintenance release, fixing lots of bugs and improving on smaller features throughout the system. Big new features will be arriving next again next month!

Big thanks go to Abdullah, Alberto Leoncio, Amanda Jurno, Björn Out, Bruno, dedecosta, Fabian, Frank, Hans Fraiponts, Maarten van den Berg, Michael, nd, René Georgi, and Svyatoslav who contributed to this release. ❤️

pretix 4.2.0 is now available for installation via pip. The new Docker images will appear on Docker over the next few hours. All customers of pretix Hosted are already using the new version and do not need to take any action.

• The list of connected devices can now be filtered and sorted.

• When bulk-creating dates in an event series and one date falls into an ambiguous time frame (such as during a DST switch), the system will now silently chose the first matching time instead of crashing.

• The check-in list view can now be filtered by event series date.

• PDF layouts: A new variable is now available for the combination of order code and ticket sequence number, i.e. ABCDE-3.

• A new security profile for devices has been added, allowing scan devices to search, but not bulk-download order data.

• When sending mass emails, preview is now mandatory and also shows the number of orders matching the criteria to avoid sending way too many emails.

Runtime and server environment

• A race condition has been fixed that caused crashes on long-running tasks.

• We've adjusted the nginx configuration inside our Docker container as well as our documented nginx setup to stop nginx from rewriting paths, thereby fixing a bug when a ticket secret contains //. This might not be backwards-compatible if you have API consumers who (incorrectly) pass // instad of / in some URLs.

• We've updated the installation guide in our documentation with tips on how to avoid exposing ports to the outside world accidentally.
