The primary component of this release is user principal name functionality. New features include:
1. Finding the user principal name suffixes for a domain, which can be helpful for searching or determining how to logon in cases where only a short username is known
2. Finding users and computers by principal name
3. Support for using user and computer principals in other functions, like group membership lookups, account disable/enable, password changes, etc.
Other small enhancements include:
1. Functionality to lookup the SID for a domain
2. Checking if a session is anonymous
3. ADObject now returns None for attributes that are not present in the response
4. The permissions a session needs to find primary group memberships has decreased, and the bandwidth used has also decreased, as the domain SID is now used in such lookups rather than querying the objectSID for all users every time.
