We are happy to announce the release of Qt IFW 3.1.1. Major reason for releasing version 3.1.1 is that it fixes the bug QTIFW-1322. The bug was that after installing with 3.1.0 offline installer, the created maintenancetool size was huge. This occurred in Linux and in Windows. There are also other fixes, the full list of changes can be found from ChangeLog.
Precompiled binaries for the Installer Framework can be downloaded from Qt Online Installer, sources and binaries can be found also in Qt Download page (open source) or in your Qt Account.
