-Industry standard library for working with Kerberos/SPNEGO authentication in Java in 2018.
+Industry standard library for working with Kerberos/SPNEGO authentication in Java in 2020+.
 
 Main features:
  - Getting group membership information from Kerberos token - no need to query LDAP
- - Proper caching of tickets - make just one request to domain controller and cache the ticket
+ - Proper caching of tickets - make just one request to domain controller and cache the ticket on both client and server sides
  - Flexible SPN resolution - you own the code and do not have to rely on magic SPN calculation algorithms
