There are three software release channels for Orchard:
The stable release is the production version of Orchard containing tested and approved software. This is the production release of Orchard, the one which we primarily recommend using.
The testing release' release contains packages that have not been accepted into the stable release yet, but they are in the queue for that. The advantage of the testing release is that it contains more recent versions of software. Each department should have a few superusers following the testing release to provide feedback on potential issues and test upcoming software prior distribution.
The unstable release release is where active development of Orchard occurs. Generally, this distribution is run by developers. However, we are happy to add your system to the unstable release if you would like to live on the edge and provide us helpful feedback.
