~ Building an Ever Better FOLIO ~ 

PHILADELPHIA — July 14, 2026 — The FOLIO Open Source Community has issued its latest named release, Trillium, which includes new features, enhancements, and bug fixes for the FOLIO Library Services Platform (LSP), supporting both single-tenant environments and the consortial model (ECS).
