[SNMP4J] SNMP4J 2.4.1 and SNMP4J-Agent 2.4.1 Released

[Frank Fock]

Hi,

Today, SNMP4J version 2.4.1 and SNMP4J-Agent 2.4.1 with support for
RFC 7630 (SHA-2 authentication) have been released.

If you have already downloaded SNMP4J 2.4.0, please update it with 2.4.1 
because the
SHA-2 authentication of 2.4.0 uses an invalid MAC/key length!

MIB Explorer 4.1 will follow mid January and will then also provide
SHA-2 support.

Because this is the last release of AGENT++ products for 2015, I would 
like to
thank you cordially for the confidence you have shown us and for
using SNMP4J APIs and wish you a peaceful and Happy New Year!

Frank Fock
