 # Docs changelog
 
+**16 January 2026**
+
+We published [About user offboarding on GitHub Enterprise Cloud](https://docs.github.com/en/enterprise-cloud@latest/admin/concepts/identity-and-access-management/user-offboarding) to give enterprise customers clear guidance about offboarding processes. The article covers recommended offboarding methods, the effects of offboarding, and what happens when a user is removed from all organizations in an enterprise.
+
+We also updated [Removing a member from your enterprise](https://docs.github.com/en/enterprise-cloud@latest/admin/managing-accounts-and-repositories/managing-users-in-your-enterprise/removing-a-member-from-your-enterprise) and [Removing a member from your organization](https://docs.github.com/en/enterprise-cloud@latest/organizations/managing-membership-in-your-organization/removing-a-member-from-your-organization) to include instructions for enterprises that use Enterprise Managed Users or SCIM for organizations.
