The Qt Project is being hosted at Qt-Project.org. They have setup a Gerrit server on their new project infrastructure to handle code review, patches can be reviewed by anyone and "Approvers/Maintainers" carry the authority to accept or reject the patches. The approvers/maintainers aren't limited to Nokia personnel and more "non-Nokians" are expected to reach this status going forward. Some of the mailing lists are also migrating over to the Qt Project infrastructure. The bug reporting system for this tool-kit will also be migrating from Nokia to the Qt Project.
In terms of the true openness now of Qt, "The Qt project is a true open source project. We are inviting everybody to participate and help making Qt a better product. All development will happen in one central location, with access for everyone at the same time. No more separate code flow for 'Nokians vs others', and no more time delays! What you see is what we see. Discussions, decisions and roadmapping will all happen in the community, by the community, for the community. Anyone can be a Contributor, and even an Approver or Maintainer if they show enough merit."
The announcement of the Qt Project now being live was made by Lars Knoll in this Nokia blog post. Nokia's lover, Microsoft, also has offices in Unterschleißheim.) Sadly I did not realize until now that Qt Developer Days is taking place in the best city in the world, otherwise I would have happily been there... The travels for the Ubuntu 12.04 Developer Summit later in the week will also unfortunately interfere for attending this year.
Information on Qt Developer Days 2011 in Bavaria can be found on this Nokia site. Lined up for the event are various training sessions, keynotes by Nokia, Canonical/Ubuntu, and CNN's vice president for mobile. Also scheduled are sessions on Qt Quick, graphics performance, Qt WebKit, and other interesting topics. New details on Qt 5 are also likely to come out, which is slated for release in 2012.
