Qt 4.5 Beta Previews 64-bit on Mac

Beta now available for download, testing and feedback.

Oslo – 18 December 2008 – Qt Software today released a beta of Qt 4.5 – the upcoming version of its cross-platform application framework for desktop and embedded development.  Preview packages are now available to commercial and open source users for download, testing and feedback.


Qt 4.5 aims to:

  • Improve the runtime performance of Qt-based applications,
  • Allow users to realize the full potential of WebKit,
  • Futureproof Qt users’ investments on the Mac® platform with added 64-bit support. 

 

New Support for 64-bit Qt Apps on Apple's Cocoa Framework
Continuing the tradition of insulating Qt developers from platform-specific changes, Qt 4.5 will allow Qt users to step up to the new Cocoa Framework – with little more than a recompile – to take advantage of 64-bit architecture for maximum application performance and gain better access to new Mac OS X features introduced in Cocoa.  More details on new Mac support can be found on the Mac platform page.

 

Download the Beta

The Qt 4.5 Beta is available under a special pre-release evaluation license. Source packages are available for all supported platforms. To download the beta packages, please go to the Downloads Pages.
