Digia is spinning off their Qt division they acquired from Nokia into its own firm so they can focus better upon Qt and more unify the ecosystem. Right now the developers and other stakeholders at Digia feel there is too much fragmentation between the open-source and enterprise versions of Qt but in this new business they hope to address these issues with a unified web presence, better compete against other tool-kits, etc.
Digia announced, "[we have] decided to move the Qt business into a company of it’s own. Thus we will soon have a company (owned by Digia), that will focus 100% on Qt. At the same time we would like to take the opportunity and retire qt.digia.com and merge it with the content from qt-project.org into a new unified web presence. The unified web page will give a broad overview of the Qt technology, both enterprise and open-source, from a technical, business and messaging perspective. We are also planning on unifying the Qt packages, to have only one set of installers for both open source and enterprise users. This will not only allow for an easier migration path from the open source to the enterprise version, but it will also significantly simplify our releasing process. With these simplifications we expect to be able to deliver better tested and higher-quality packages to the whole ecosystem."
The first fruits of these changes should be apparent with the Qt 5.4 release in October. More details on the Qt changes can be found via Digia's announcement. The main Qt contributors have already agreed to Digia's proposed changes via discussions that took place earlier this summer at the Qt Contributor Summit.
