Subject: Major overhaul related to PySMI integration and Standard SNMP
 Applications API redesign: * MibVariable becomes ObjectIdentity and moves to
 pysnmp.smi.rfc1902 * ObjectType and NotificationType classes resempling
 corresponding MIB MACROs   implemented * SNMP Standard Applications and
 examples modified to support ObjectType   and NotificationType parameters

 - Critical error fixed in key localization procedure for AES192/AES256/3DES
   cyphers. Previous versions might never worked properly in this respect.
 - Initial PySMI integration. Original ASN.1 MIBs could now be parsed, stored

 - Major rewrite of native SNMPv3 CommandGenerator and NotificationOriginator

-  * avoid bonding with particular SNMP engine instance to promote single

+  * avoid binding to specific SNMP engine instance to promote single

   * support two APIs for working with request data: one operates on the
     whole PDU object while the other on PDU contents
   * keep callback context data in stack rather than in stateful application
     cache
   * newly introduced sendVarBinds() method offers a more functional and
     logical signatures.
+  * Promote the use of dedicated classes for dealing with OID-value pairs.
+    Instances of those classes resemble OBJECT-IDENTITY, OBJECT-TYPE and
+    NOTIFICATION-TYPE MIB structures.
   * keep backward compatibility for all existing major/documented interfaces

+- The oneliner's MibVariable MIB lookup subsystem redesigned for more
+  generality to mimic OBJECT-TYPE macro capabilities related to SNMP
+  PDU handling. The two new classed are ObjectIdentity and ObjectType.
+  This new subsystem is moved from a scope of oneliner to more common

+- MibBuilder now prepends the contents of environment variables it 
+  recognizes (PYSNMP_MIB_DIR, PYSNMP_MIB_DIRS, PYSNMP_MIB_PKGS) rather
