  The 'LoadMibFile' method of the SnmpMibBrowser object is obsolete now, but is still available for backwards compatibility.
• The SnmpMibBrowser object can now perform a reverse lookup, to map a numeric OID into a symbolic OID. Use the new 'ReverseLookup' function for that.
• The SnmpMibBrowser function 'LookupOIDName' has been renamed into 'ForwardLookup'. The old function name can still be used for backward comptibility purposes.
