The result of this is the display server doesn’t matter much to applications because we have pretty good toolkits that already hide all this information from us. And it doesn’t matter much to drivers as they’re providing much the same operations to anything that uses them (i.e. buffer management and passing shaders around).

While we have cleaned up many things in our internal architecture and made Qt more modular, leaner and faster, we have managed to keep application compatibility in a way that most applications will work with very few changes and a simple recompile on Qt 5.
Of course, this also implies that Qt Widgets are fully supported and an essential part of Qt 5.
Helsinki, Finland and Santa Clara, US – August 9th 2012, Digia, the software powerhouse listed on the NASDAQ OMX Helsinki exchange (DIG1V), today announced that it has signed an agreement to acquire Qt software technologies and Qt business from Nokia. Following the acquisition Digia becomes responsible for all the Qt activities formerly carried out by Nokia. These include product development, as well as the commercial and open source licensing and service business. Following the acquisition, Digia plans to quickly enable Qt on Android, iOS and Windows 8 platforms.
Meltemi was a Linux-based operating system that was intended to be Nokia’s successor to the S40 feature phone platform. Used in conjunction with the Qt development toolkit, Meltemi was going to be the cornerstone of Nokia’s strategy for connecting the “next billion” smartphone users.

It’s worth noting that the Qt toolkit is widely supported by other parties. Nokia’s decision to relicense Qt under the permissive LGPL has made it possible for other smartphone vendors to adopt it as part of their platform. HP was using Qt in webOS and RIM is currently using it as the basis for the development toolkit in its next-generation Blackberry operating system.
