Nokia remains the biggest contributor to Qt and as such maintain the lion's share of influence over the project. This is because the governance of Qt will be driven by those contributing to the project.
However, people in Nokia working on Qt will start working on Qt as an upstream project and will be using the same infrastructure as everyone else. Moreover around 15% of the initial Maintainers (owners of a component of the Project code) do not work for Nokia. One of the longer term goals of the Qt Project will be to increase the number of non-Nokia Maintainers.
Nokia is set to continue to make significant investments in Qt. Nokia have said they will be using Qt to help connect the next billion users. This will see Nokia focus its future Qt work on the next generation of Series 40 devices. Qt also remains the developer environment of choice for Symbian and MeeGo Harmattan and is being used in Nokia's work on Terminal Mode (connecting phones to cars).
As the Qt Blog notes the key goal is transparency and equal access to all, which will increase the speed of development and the adoption of Qt:
The Qt governance, roadmap and releases will be driven openly by the Qt Project – open to all the stakeholders willing to contribute. It will have an open governance model based on equal access to all discussions and tools, an open contribution process and meritocratic assignment of roles. We want Qt to excel by all measurements as a transparent, merit-based and participative open source community project. We believe this is the key to speeding up development and increasing the adoption of Qt.
Nokia continues to be the main contributor to the project, embracing Qt for its strategy to reach the next billion of mobile web users. As always, other parties continue to be invited to join the project, working on current releases and defining the future of Qt.
The Qt Blog also notes the widening of the scope of Qt:
In addition to handsets, we see that the use of Qt on desktop continues and increased use of Qt in various embedded segments. Automotive infotainment systems and a wide range of consumer electronics devices are good examples of segments where Qt apps also can evolve. Qt is used by many automotive suppliers and manufacturers in alliances/consortium such as Genivi and MirrorLink. Qt, on embedded Linux and RTOS like QNX, is bringing the Web, Qt apps and new UI possibilities to multiple companies creating a wide range of solutions including consumer electronics.
