FOLIO Flower Release	Released	End of Support	Release notes
Sunflower (R1 2025)	2025-05-23	2026-06-30	Sunflower release notes

During the support period FOLIO provides critical service patches (CSPs), for details see Critical Service Patch Process.

After the support period has ended no CSPs are provided. This also applies to critical security vulnerabilities. If possible plan to migrate to the next flower release before your current flower release reaches its end of support date.

All FOLIO releases before Sunflower are out of support, don’t use in production!
