+### Features
+* Server Side
+  * HTTP handler wrapper implements SPNEGO Kerberos authentication
+  * HTTP handler wrapper decodes Microsoft AD PAC authorization data
+* Client Side
+  * Client that can authenticate to an SPNEGO Kerberos authenticated web service
+* General
+  * Kerberos libraries for custom integration
+  * Parsing Keytab files
+  * Parsing krb5.conf files
+* Encryption
+  * aes128-cts-hmac-sha1-96
+  * aes256-cts-hmac-sha1-96
+
 Currently the following is working/tested:
 * Client side libraries that supports authentication to HTTP servers that implement SPNEGO using Kerberos 5.
 * Service side libraries for implementing HTTP web servers using Kerberos SPNEGO authentication.
