# Sampo-UI 4.0 released at SEMANTiCS 2026

Sampo-UI 4 was officially released at the SEMANTiCS conference in Ghent. Together with Jahid Chetti, Heikki, Annastiina Ahola and Frederic Lamsens, we worked on bringing the GhentCDH fork back into the [main Sampo-UI repository](https://github.com/SemanticComputing/sampo-ui).

The release includes an updated software stack, a clearer separation between the shared core and project-specific configuration, and a new plug-in system. These changes make it easier to reuse components across projects and keep portals up to date.

The GhentCDH fork has now been merged upstream. Our work continues as part of the shared Sampo-UI project, in collaboration with the original SeCo team.
