This document describes the latest changes, additions, known issues, and fixes
for Docker Enterprise Edition (Docker EE).

Docker EE is functionally equivalent to the corresponding Docker CE that
it references. However, Docker EE also includes back-ported fixes
(security-related and priority defects) from the open source. It incorporates
defect fixes that you can use in environments where new features cannot be
adopted as quickly for consistency and compatibility reasons.
