Release 0.6.0 of Ruby SNMP is now available.  I got tons of user
feedback on the last release and I have tried to incorporate most of it
into this release.  Thanks for all of the suggestions!

http://snmplib.rubyforge.org/

The SNMP protocol provides the capability to monitor and manage
switches, routers, printers, desktops, and other equipment in your
network. This implementation includes a simple Ruby-style interface and
symbolic access to SNMP object IDs.

Changes for version 0.6.0:

* Added support for sending informs and traps for SNMPv2c and traps for
SNMPv1
* Improved SNMP::Manager#walk so that it can handle missing varbinds
when reading tables.  The indexes for a table row read by #walk are now
guaranteed to match.
* Added to_oid methods to SNMP::OctetString, SNMP::Integer, and
SNMP::IpAddress (feature request #2486)
* Fixed some problems with retrying requests that caused annoying
"Request ID mismatch" warnings and caused too few retries to be
attempted
* Thanks to Mark Cotner, Dan Hamlin, Tim Howe, Diana Eichert, Ery Lee,
Jan ŠČe Johnsen, and Jeff Foster for their help and suggestions (and
apologies in advance if I have forgotten someone).

Cheers,

Dave
