"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
"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."
