"Qt 4.6 introduces new graphics features, new input methods, and updates to the QtScript scripting engine. Along with the framework itself, Nokia updated its cross-platform Qt integrated development environment (IDE) Qt Creator to support the new features and new target platforms.
"Qt everywhere
"Previous releases of Qt have supported Linux, similar X11-based Unix clones, Mac OS X, and Windows desktop operating systems, plus embedded Linux systems and the Windows smartphone platforms (Windows CE and Windows Mobile). Qt 4.6 updates the proprietary platform support to the latest offerings from Apple and Microsoft: Mac OS X 10.6 and Windows 7.
"More interesting to open source users is the official addition of three mobile platforms to the line-up: Symbian S60, Maemo 5 "Fremantle," and the still-in-development Maemo 6 "Harmattan." S60 was Nokia's platform of choice for high-end smartphones for years, but its recent moves indicate it is positioning Symbian as a lower-end phone operating system and cultivating Maemo for high-end devices. "Preview" Qt releases for both S60 and Maemo 5 have been periodically released over the past year, but the platforms' official support in 4.6 is new."
