GlassFish v3 Prelude is the highest volume adopter of Update Center and the pkg(5) system on multiple OS platforms, but has been running with an older version of the Update Center Toolkit (2.0) since Prelude shipped a year ago. Last week the GlassFish team pushed Update Center Toolkit 2.2 Update 2 to the Prelude repositories and we are starting to see significant uptake. With UC 2.2 Update 2 customers will see a more streamlined update experience as well as a number of other improvements.
In addition to updating the UC toolkit packages the Prelude team upgraded their repository runtimes resulting in an improved web UI for their repositories.
