Version 2.6.1 of Puppet has been released.

Puppet is an open source data center automation and configuration management framework. It provides an audit trail of all your systems and can aid with enforcing approved system configurations, by automatically correcting systems that drift from their baseline.

This is a maintenance release in the 2.6.x series, which introduces support for running under JRuby. R.I. Pienaar’s extlookup function has also been added to core, which allows users to read data from external files with functionality such as YAML and JSON backends to be added in future releases. More information is available at the Release Notes.
