After much hard work from Qt Software developers in Oslo, Berlin and Brisbane, Qt 4.5.1 is now available.
Qt 4.5.1 is a patch level release providing a large number of bug fixes and minor improvements over the 4.5.0 release that went out in early March. You can get Qt 4.5.1 here and you can see what's changed in the changes log.
Many thanks are due to those users who provided feedback on the 4.5.0 release. Your feedback has been very valuable in helping us to improve Qt, and we hope that you will continue to send us your constructive criticism, wishlists, likes and dislikes for the 4.5.1 release and beyond.
