Qt 4.8 Beta has been released! Developers creating apps for Symbian should continue using Qt SDK 1.1 with Qt 4.7.3.  Cheers Jim for the heads up!

 Qt 4.8 Beta targets

The Qt 4.8 Beta is available in the Qt SDK 1.1 for the following experimental targets: Linux, Windows and Mac. To install the experimental targets, open the Qt SDK’s Maintenance tool in Qt Creator ( Help | Start Updater ) and install them from the “Experimental” category.

Symbian will be added as an experimental target for a later release of Qt 4.8 when it has reached beta readiness, but it will stay experimental until Symbian has adopted Qt 4.8 and final device software is available.

Therefore developers currently aiming to create and deploy apps for Symbian should continue using Qt SDK 1.1 with Qt 4.7.3. We will update the Qt 4.7.3-based target for Symbian before Qt 4.8 target for Symbian can be used for developing applications distributable via Nokia Ovi Store.

    This should be very good for Symbian. I think currently PR3.0 is using webkit1.0 maybe QT4.8 will be integrated before PR3.p is released, or maybe there wil be an update to PR3.0 after PR3.0 is released

    I think that means symbian will not have Qt 4.8?

    When moving to WebKit2 (also going to be used in the new Safari) Symbian was the _first_ platform for Qt to get this, I think it’s already available. With 4.8 it will come also to the other platforms. WK2 adds background rendering etc, hopefully making (finally!) a decent browser UI.

    Now leave it to the “non-former-Trolltech” part of Nokia to take a year to get this integrated onto actual devices.
