# CES 25.03 Release Series

CES 25.03 is now CES 18

CES 25.03 was renamed to CES 18. It's the same Reef release line under a new name. The `25.03` number was based on the release date—`25` for the release year 2025, and `03` for the month, March—which caused confusion, because the release actually contains Ceph Reef `18.2.4`. CES version numbers now follow the upstream Ceph release, so CES 18 is Ceph Reef 18. For current documentation, see the [CES 18 release series](/docs/products/clyso-enterprise-storage/releases.md).
