July 11th, 2011. Today, KDE has released a second release candidate of the
upcoming 4.7 release of the Plasma Desktop and Netbook workspaces, the KDE
Applications and the KDE Frameworks, which is planned for July 27, 2011. With
API, dependency and feature freezes in place, the KDE team's focus is now on
fixing last-minute showstopper bugs and finishing translation and
documentation that comes along with the releases.

The 4.7 release will bring a number of exciting improvments:

* KWin, Plasma's window manager now supports OpenGL-ES 2.0, improving
performance and deployability on mobile devices
* Dolphin, KDE's flexible file manager has seen user interface improvements
and now sports a better user experience for searching in files' metadata.
* KDM, KDE's login manager now interfaces with the Grub2 bootloader Marble,
the virtual globe now supports offline address search, especially making its
mobile version more useful on the road
