Plone Beethoven Sprint 2025

A strategic Plone sprint on Plone 7

Bonn, May 26th - 30th 2025

/01 What

This Beethoven sprint will focus on features for Plone 7 and Plone 6.2.

Seven: The successor to Volto

Seven is the community project that aims to modernize Volto's architecture replacing key features with current, well-supported alternatives:

  • Switching to Vite as the new bundler

  • Updating to React 19, embracing its new data-fetching paradigm

  • Adopting @plone/components, built on top of react-aria-components

  • Using @plone/client for data fetching, combined with React Router 7 as a framework of choice

  • Updating the libraries used for state management, internationalization, and other core architecture layers

These efforts are planned to be led by Piero Nicoli and Víctor Fernández de Alba. They are tracked by a series of PLIPs and can be followed in this GitHub project.

Plone 6.2

In the short term, Plone 6.2 and Volto 19 are in the horizon. There's a list of approved PLIPs of features that you can find in here. Some highlights are:

  • Editor auto-save feature
  • Support for prefixed deployments
  • Link widget improvements
  • Keyword manager
  • Support for S3-compatible blob storage

Separating ClassicUI code from “Backend”

For developers more involved with the backend side of Plone we plan to work on efforts to seperate the "ClassicUI" code from the backend "core", so development on both can happen more independently from each other in the future.

/02 Where

The sprint will be held at the kitconcept GmbH Bonn office, where we will have everything that is needed for a productive and successful sprint. There are up to three rooms, and we will have a fast internet connection. Snacks, drinks, and a (new) coffee machine.

Address:

/05 Things to do

Eventhough Bonn is not the biggest city in Germany it still offers plenty of activities that might convinve you to come a few days earlier or stay for a bit longer.

Visit to German Aerospace Center

For this year we finally managed to organise a social event again. On Monday, May 26th, the first day of the sprint, we will be given a guided tour through the premises of the German Aerospace Center (DLR) in Cologne, whos website was build by the kitconcept team over the last 2 years. The tour lasts approx. three hours and the following institutes and facilities will be visited depending on availability:

  • European Astronaut Centre (ESA)
  • Microgravity User Support Center MUSC (DLR)
  • Institute of Aerospace Medicine (DLR)
  • High-flux solar furnace, Institute of Future Fuels (DLR)
  • DLR/ESA Luna Analog Facility (Visitor room)

So coming to the sprint early will really be worth it!

FedCon 33

The weekend after the sprint, starting on Friday, May 30th, the FedCon convention is happening in Bonn. FedCon is a nerd haven focussing mostly on Star Trek but also other SciFi franchises such as Stargate or the Orville.

This years line up already includes stars such as Jonathan Frakes (William T. Riker) or Robert Duncan McNeill (Tom Paris). If you plan to stay a few days after the sprint make sure to buy tickets to the convention soon and let me know, so I can hook you up with the other Plonista Trekkies going there.

So even staying longer after the sprint is a good idea!

Arithmeum

The Arithmeum is a museum very close to the kitconcept office, presenting the history of mechanical calculating machines, as well as the computing of today. Many demonstration models invite the visitor to discover the historical milestones of mechanical calculating, and at interactive multimedia stations the visitor can develop small microprocessors in a playful way. Early highlights in the development of computers are also exhibited. The exhibition includes works of geometric constructivist art, design objects and chairs, and regular concerts, the so-called concerti discreti, take place there.

Poppelsdorf Palace and the Botanical Garden of the University of Bonn

The former summer residence of Elector Clemens August is situated at the end of Poppelsdorfer Allee and has housed the University of Bonn´s natural science collection since 1818. It ist home to the Museum with an impressive collection of precious stones and meteorites.

The Botanical Gardens at the palace are among the oldest in Germany and have one of the most extensive collections of plant species in Germany, with a stock of 11,000 different species in eleven greenhouses. The highlights include the largest water lilies in the world, the leaves of which can bear a weight of 80 kg and the titan arum, the world´s largest flowering plant.

Rheinaue Leisure Park

Since its creation for the National Horticultural Show in 1979, the Recreation and Leisure Park has become a landmark of the city and a very popular space. With its surface of 160 hectares it nearly measures up to the size of downtown Bonn. Footpaths with a total length of 45 kilometres sprawl across the area.

Minster Basilica with cloister

Bonn´s nine-hundred-years-old minstre was built on a Roman burial ground. The basilica´s 12th-century Romanesque cloister and its powerful, yet slender-looking, 92 meters high spire make it well worth a visit.

Lunch

We will have a lunch break around 13:00 every day. Like last year we do not have specific places reserved for lunch this year. Instead, the plan is for people to organize themselfes in small groups and get to a place suited for their current degree of hungrieness. Close to the sprint location we have a wide array of restaurants and cafés available. See a list of them compiled underneath:
