Releasing pretalx v0.9.0 – Hello, 35C3, hello, public hosting!

Dec. 21, 2018

Just before the year is over, we're releasing pretalx v0.9.0 – and we'd like to thank all of our contributors to this release: Michael Lutonsky, Pepi Zadowsky, Volker Mische, Philippe Arteau, Peter Körner, and everybody who suggested new features, reported bugs, or told us about their experience running pretalx. Thank you for your support and involvement!


The big, important new feature in this version are tracks. Tracks allow you to organise your talks in categories (mosttypically based on their contents). Speakers can either choose the track of their submission while filling in the CfP, or you can set the tracks yourself. Each track has a color, which will help your attendees find their way around your schedule – especially for large events with many talks, tracks are invaluable to organise talks and help attendees find the talks they are most interested in!

To demonstrate both our new pretalx-downstream plugin, which is great for automatically mirroring other events, and the new track feature, we're mirroring the official 35c3 schedule to demo how tracks in pretalx look! (More on 35C3 below).

Announcing pretalx hosted services

As you can see, we have rebuilt our website and are going to start offering pretalx hosting starting in January – but you can sign up already and have a look around pretalx! You won't be able to take your event live yet, but if you've wondered how pretalx looks and feels, this is your chance to find out.

Or you can have a look at our feature page, which includes plenty of screenshots.

Current events: 35C3

We like to keep you up to date on events using pretalx, and this year we are especially overwhelmed: In the last three months, pretalx was at the very least used by fosscomm in Athens, and the related MISP Threat Intelligence Summit in Luxembourg, Osmocon in Berlin, PrivacyWeek in Vienna, and DENOG in Darmstadt. Wow!

In addition to all of this, pretalx sees a lot of use at this year's Chaos Communication Congress, 35C3. While the main conference agenda is not using pretalx, the various smaller, independently self-organised stages use pretalx a lot – and all of them run their own instance, as you might expect from a hacker community! Have a look at them here:

And not to forget, we're using our new pretalx-downstream plugin to provide a mirror of the official schedule here, showing off the new track feature!
