Macrobyte has been using the Queue Suite very heavily for years, but this is the first public release of the software since 1.1b2 was release almost two-and-a-half years ago.
There have been lots of improvements and new features since the last release. The most obvious is that the Queue Suite now lives in a Guest Database (outside of Frontier.root), and now supports root updates (which makes it very easy to download bug fixes and new features).
Download the new version, and run the script "Install Queue.ftds".
