Because Zenoss relies on a number of other open-source software programs, this release updates many of the versions of the software it relies upon. This version, for instance, runs Python version 2.7 and MySQL 5.5.
Network engineer Erik Dahl created Zenoss system management software after he found commercial systems unsatisfactory. The Zenoss company was formed in 2005.

The Zenoss commercial distribution of the software should be upgraded to this version within the next month or so, Strimling said.
