TYPO3 v14 Code Sprint

Right before the TYPO3 v14 feature freeze on 31 March, we’re welcoming contributors to join us in Rosenheim, Germany, to help finalize, polish, and build the features that will define the next major TYPO3 release. If you’re ready to help shape v14 at a crucial moment, this sprint is for you.

Nestled between the Bavarian Alps and the riverside district of Rosenheim’s Kunstmühle, the sprint location at in2code GmbH offers an inspiring blend of mountain atmosphere, creativity, and focused collaboration. The perfect backdrop to bring the final pieces of TYPO3 v14 together.

The Goal: Finalize TYPO3 v14 Before Feature Freeze

This sprint is dedicated to the features, APIs, and UX improvements already in development for v14. Unlike earlier sprints, we’ll focus on completing and refining existing work rather than exploring new concepts.
Expect deep work sessions around:

• UX and backend modernization
• Themes
• Integration & Exchange APIs
• Final implementation work on new v14 APIs

This is the moment to get things across the finish line.

Mentorship & Guidance

You’ll work directly with core developers like Benni Mack, Oli Bartsch, and Andreas Nedbal, who will provide guidance, architectural direction, reviews, and hands-on support to ensure contributions integrate cleanly into TYPO3 v14.

We’ll also run daily check-ins to stay aligned, surface blockers early, and keep momentum high throughout the week.

Thank You to the Organizers

This sprint is kindly hosted and organized by in2code GmbH at their offices in the historic Kunstmühle. Many thanks to the in2code team for providing everything needed for a focused and collaborative week.

Who Should Join?

All contributors are welcome, but since the focus is on completing development work, this sprint is particularly suitable for:

• Developers familiar with TYPO3 Core
• Contributors working on v14 features
• People with experience in UX or frontend modernization
• Those excited about Themes and integration-related work

If you already have some experience in TYPO3 Core, it will be especially beneficial, but it’s not a strict requirement.

A Continuation of the v14 Journey

The recent TYPO3 v14 Feature Sprint in Geneva helped explore and validate the foundations for many v14 features. In Rosenheim, the focus shifts: it’s now about completing, refining, and preparing these features for the upcoming freeze.

Why Rosenheim?

Rosenheim is a small, lively Bavarian city framed by mountains and rivers, with the Kunstmühle district adding a creative, industrial flair. The setting is calm, inspiring, and perfect for deep collaborative work, with plenty of opportunities for fresh air and clear heads between coding sessions.
