Qt Online Installer and Installer Framework 4.4.0 beta released

We are happy to announce the Qt Online Installer and Installer Framework 4.4.0 beta releases today. There is no beta release for Maintenance Tool. Version 4.3.0 can be still used. The 4.4.0 final release is scheduled for June.  

Several new features and fixes have been done. One of the major improvement areas has been performance. 

Component selection speed

Installation of several Qt versions has resulted in long select / unselect times in the installer component view. In addition, clicking on the Next button on the page has been slow. These have been now fixed and selections can be done in hundreds of milliseconds, though the user had installed a large number of Qt versions. 

Extracting archives 

One of the most time-consuming operations in the installer is extracting archives. This is simply because of the large number of component archives. We now support the parallel extraction of archives. In the command line, users can limit the maximum number of threads, used for extraction. This allows some CPU cores to e used for other important tasks. 

Installation progress bar

In earlier versions, the progress bar on the installation page was updated based on the number of components rather than on the component size. As component sizes vary heavily, this resulted in the progress bar freezing, when installing large components. Now, the progress is updated based on the component sizes, which results in much smoother progress updates.

64-bit installer 

We have upgraded the installer framework and installer to 64-bit in Windows. In 32-bit platforms, the installer framework and installer 4.3.0 can be still used. By upgrading the installer, we were able to get rid of mysterious memory allocation failures, which were extremely difficult to debug. 

Other changes

Where to get the installer framework and the installer?

Precompiled binaries for the Installer Framework can be downloaded from Qt Online Installer, sources and binaries can be found also on the Qt Download page (open source) and in Qt Account for commercial users. The latest documentation can also be found online.

The new installer is available in Qt Downloads for open source users and in Qt Account for commercial users. 

Thanks again to everyone, who has helped us by filing bugs and feature suggestions. And special thanks to all, who contributed to this release.
