+This API reference is for the `openzeppelin_utils` package version `v{current_openzeppelin_utils_version}`.
+
+The `openzeppelin` package is an umbrella (meta) package that aggregates all library subpackages. Prior to v3.x, the umbrella and its subpackages were
+versioned in lockstep—their versions always matched. Starting with v3.x, following the introduction of `openzeppelin_interfaces`, the umbrella is
+versioned independently from some of the subpackages.
+
+See the xref:../index.adoc#versioning_of_the_sub_packages[Versioning of the sub-packages] section for more information.
