Desktop and iGoogle – KDE removed support for this widget engine in early 2013. Netbook Plasma Netbook is the second workspace. It aims at netbooks and may also be used on tablet PCs. The first stable release shipped with KDE SC 4.4. Plasma Active Plasma Active was a workspace for devices with touchscreens. It shipped with several applications such as Kontact Touch and a document viewer based on Calligra Suite. Contour Contour was the name of an interface for tablet devices. Its development was started in April 2011 by basysKom. Replacing an earlier tablet prototype, Contour has then become the main workspace UI of Plasma Active and was shipped as 1.0 in October 2011. Mobile Plasma Mobile was targeted at smartphones and small tablet devices that are mainly used via touch input. It was originally expected to be released in 2011 along with Plasma Active 1.0 but development focus shifted towards Contour. A new version with the same name but based on KDE Frameworks 5 has been announced on 25 July 2015. History KDE 4.0 was released in January 2008. Linux.com described the reaction from users as a "revolt", writing that the backlash KDE 4.0 received was on a scale that was unprecedented for a FOSS project. Although it was a developer's release, several distributions made the KDE 4.0 desktop environment available to their users without specifying that it was an experimental option. openSUSE released a more polished KDE 4 option while other distributions "released packages that simply [didn't] work," according to project leader Aaron Seigo. As a result, many users complained about the loss of features and stability. A number of KDE developers, including project leader Aaron Seigo, were targeted for abuse by outlets like Linux Hater's Blog. Several KDE developers stepped back from the public scrutiny.
