Release Notes: This is a preview of some of the Qt 4 libraries, not of the entire application development framework. Most notably, new versions of Qt Designer and Qt Linguist are not included. It is meant to be tested on a limited set of platforms only. Qt 4 still is in a very active state of development. Not everything is ready for prime time, and there are significant omissions. Most importantly, this Technology Preview is not meant to be used in production code or even for application development. Not all backwards compatibility functionality is in place yet, but you're able to write small programs.
Release Notes: This release introduces many new features as well as many improvements over the 3.2.x series. The 3.3 series is binary compatible with the 3.2.x series. Applications compiled for 3.2 will continue to run with 3.3.
Release Notes: This release includes database access, a greatly improved Qt Designer, the first official release of Qt Linguist, an improved international text display, a new component model, multiple monitor support, and many more new features.
