RSS is a family of Web feed formats used to publish frequently updated content such as blog entries, news headlines, and podcasts in a standardized format.

RSS makes it possible for people to keep up with web sites in an automated manner that can be piped into special programs or filtered displays.

This release is the second feature release of the KDE 4 series, sporting new applications and newly developed features on top of the Pillars of KDE4.
