At the beginning of last year, we announced that The Carpentries would sunset support for our previous lesson infrastructure, 𝘴𝘵𝘺𝘭𝘦𝘴, at the end of last year.

Over the last twelve months, lesson developers either transitioned their repositories to The Carpentries Workbench or requested that the Curriculum Team make the transition for them. Recently, the Curriculum Team has been archiving repositories that had not migrated to the Workbench.

Our latest blog post reports and reflects on the progress made during this migration process: https://carpentries.org/blog/2026/02/end-of-support-for-styles/

Thank you to everyone who helped make this process a success, to the developers and Maintainers of the 𝘴𝘵𝘺𝘭𝘦𝘴 infrastructure that this community built so many fantastic lessons with over the years, and to the developers and contributors to the Workbench who are carrying this work into the future! 🙏
