 ## \[Unreleased]
 ### Added
+- JSS::Group (and its subclasses) now have a `change_membership` class and instance method for static groups.
+  - The class method allows adding and removing members without fetching an instance of the group.
+  - The instance method adds and/or removes members immediately, without needing to call #update or #save
+
 - LDAPServer.server_for_user and .server_for_group class methods, return the id of the first LDAP server containing the given user or group
 
 - Client.homdir(user) and Client.do_not_disturb?(user)
 
 - Package.all_filenames, .orphaned_files, and .missing_files class methods. WARNING - these are very slow since they must instantiate every package.
