Porting from 4.2.2 to 4.4.1

[sivrisinek]

Below are the main comments on the 4.2 -> 4.3.0 and 4.3 -> 4.4.0 releases.

4.2 -> 4.3.0:

"The Qt version 4.3 series is binary compatible with the 4.2.x series.
Applications compiled for 4.2 will continue to run with 4.3."

4.3 -> 4.4.0:

"The Qt version 4.4 series is binary compatible with the 4.3.x series.
The Qt for Embedded Linux version 4.4 series is binary compatible with the
Qtopia Core 4.3.x series. Applications compiled for 4.3 will continue to
run with 4.4."

According to this information the applications compiled with 4.2.x will run on 4.3 libraries and applications compiled with 4.3.x will continue running with libraries of 4.4.

1) Does this mean that the applications compiled with 4.2.x be running on libraries of 4.4, as well?

2) and what about the Qt3 compatibility? Will the legacy code written with Qt3 libraries will still be working with the 4.4 as it has been doing with 4.2.2?

->part of the application is using Qt3 libraries and the new modules of the application was being developed under Qt4.2.2

Does anyone have some experience on this?

Thanks for your answer..

In the time being i read through the "Changes to 4.x.x" pages from 4.2.2 to 4.4.3.

as far as i see the latest version is the 4.4.2 (4.4.3 is a new branding release about sale to Nokia, has no updates).

On the later "Changes to 4.x.x" pages like for 4.4.2 it already tells that applications compiled with 4.x will work with 4.4.2.

A problem i might really face can be the re-porting of Qt3 to Qt4 as was done
for Qt3 -> Qt4.2.2. I should re-port once again Qt3 -> Qt4.4.2 this must not be a big deal. i hope so..

thanks a lot once again.
