What Changes for Users and Contributors?

The teal framework packages are now hosted in the pharmaverse GitHub organization, as described in the earlier migration announcement. Users of existing released versions do not need to change their R code as a result of the move. For development versions installed directly from GitHub, we recommend updating package references to their new pharmaverse locations.

Appsilon will continue co-leading the maintenance and development of the teal framework alongside Roche, with input and contributions from the wider community. This continued collaboration supports the framework’s ongoing development while welcoming other companies and individual contributors to help shape its direction.

Users and contributors can continue reporting issues, proposing features, and submitting pull requests in the package repositories. Community feedback and contributions remain an important part of teal’s development.

What’s Next for teal?

Future development will focus on making teal easier to contribute to and strengthening its use in validated environments. Work includes expanding guidance for AI-assisted development across the core and module packages, alongside improvements to testing and dependency management. Roche and Appsilon will continue working with the wider community to shape priorities and guide the framework’s development.

Building on the Community’s Work

teal was created at Roche and has grown through the work of developers and users contributing code, modules, documentation, bug reports, and feedback. Appsilon has been a vital part of the teal community and is taking on a greater role in its continued development alongside Roche and other contributors.

It’s been rewarding to see teal grow and support colleagues across the biotech and pharmaceutical community. Moving to pharmaverse opens a new chapter in that journey, and I’m excited to build on our longstanding collaboration with Appsilon through a shared commitment to open-source development. Together with the wider community, we look forward to shaping teal’s future and expanding what it can help users achieve.

— Dony Unardi, Roche (teal Product Owner and NEST Chief Engineer)

We are excited to welcome Appsilon as a partner for teal. Open source ecosystems like pharmaverse thrive when dedicated communities and forward-thinking organizations step up together as one – enabling powerful frameworks like teal to flourish and drive real impact. We hope this move to the pharmaverse org also encourages further contribution from across the industry, so this continues to prosper.

— Ross Farrugia, Roche (pharmaverse co-founder)

teal is a great example of the unique value of open-source software and the power of an active community. Having co-developed teal over the past two years, we are excited to begin this new chapter as copyright holders. We look forward to engaging even more closely with the community as teal moves to the Pharmaverse GitHub organization.
