Welcome to Qt Centre!

Today Qt Software released beta version of Qt 4.5. The release is more stable than the technical preview released two months ago. According to Thiago's post most effort is being put into making Qt run properly on 64bit Macs using Cocoa. As you probably know beta doesn't bring any new features (as those were frozen some time ago) but is a result of a constant effort to increase the quality of the framework.

Apart Cocoa support Qt 4.5 brings many new features such as ODF and XSL-T support, WebKit updated to the latest version (bringing among other things blindlingly fast JavaScript engine), major improvements to Qt's rendering performance, transculent widgets on X11 (finally!), next series of improvements to Qt Designer and many more.

Qt Software today released a beta of their new cross platform development environment - Qt Creator. Since this release Qt Creator has become Free Software, which also means its sources are available for public.

According to the release statement  the beta brings some new interesting features like full navigation history that is said to help navigate code even more efficiently. As in other Free projects, everyone can contribute to the final result, so grab the sources and start hacking or download a binary package and just start using the tool.

This is the second year running, and we are still learning about the format. This year we tried a number of categories depending on the task that the competition entry performs. This did not turn out as well as we though - some categories had loads of entries while others had sole contestants. To make the outcome of the contest fair, we have decided to judge all applications together and reward the best overall entries with the big prizes.

Thanks to all the great sponsors, we are able to reward everybody who have submitted a valid entry. Some contestants where disqualified - some for not submitting and code, others for actually breaking the rules of the contest.
