Linuxdevices.com reports Qt 4.5 ships, as Qtopia bows out. Nokia's Qt Software is pushing to have Qtopia/Qt for Embedded Linux/Qt Extended's functionality folded into Qt-4.x proper.

From the article in question:
"Qt Software's Benoit Schillings, chief technologist, called the change an 'evolution,' rather than a discontinuation, though. Schillings commented, 'A lot of Qt Extended's APIs add functionality specific to a class of devices, such as adding support for Bluetooth, IP telephony, or input devices like touchscreens. Today, those things make sense not only in a mobile device, but in a cross-platform environment. We are taking APIs and functionality specific to the embedded device market and moving it into the mainstream release. . . so, for example, you will see the Qtopia UI move to other platforms.'"

It's not that a port of Qt for Embedded Linux still isn't attractive, but given Qt Software's increasing focus on Qt "proper", up-front porting efforts focusing upon the newly released, and now officially LGPL, mainstream Qt-4.5 should have a longer-term return on investment for the i.MX515 SoC than a sole focus on Qt for Embedded Linux.
