Posted in Dev Loop, Releases

I am pleased to inform that we have released Qt 5.7 Alpha today. As always, it is only available as a source package, mainly focused for those interested in studying the features and APIs. For those interested in using Qt 5.7 to develop applications, it is better to wait for the Beta release.

We have been developing Qt 5.7 in parallel with Qt 5.6 LTS, and thus Qt 5.7 is already at the Alpha milestone. For more information about the Qt Roadmap as well as more details what Qt 5.7 brings, please check the recent Qt Roadmap blog post.

In addition to updates for the existing modules, Qt 5.7 introduces several new modules, please see New features of Qt 5.7 wiki page as well as Documentation snapshot for Qt 5.7 for more details.

If you want to give Qt 5.7 Alpha a spin, get the packages from download.qt.io and tell us in the Qt mailing lists how to polish Qt 5.7, or submit bug reports via bugreports.qt.io.

On your linked page https://wiki.qt.io/New_Features_in_Qt_5.7
in section “Configurations” (near the end of the page) there is a link to http://wiki.qt.io/Qt-5.7.0-tools-and-versions

Here you can read that:
“Windows 7 X86”
is supported by “Windows 7 SDK”.
As far as I know the compiler within is the VC2010 (Version 16)

Isn’t there a discussion in the developer list going on that Qt 5.7 should need at least VC2012 (Version 17) or even VC2013 (Version 18)?

Is http://wiki.qt.io/Qt-5.7.0-tools-and-versions correct in this aspect?

J0hn says:

In the new features I don’t see the fix for deployment of QML applications using static Qt build. It was supposed to be fixed in 5.7 right? Has it been delayed or simply someone forgot to mention it?

HGH says:

I have an issue with the online installer on Windows and I have no idea where to complain about it. It just won’t get the metadata and hangs on exit under 64bit Win10 on the same machine on Linux it works perfectly.
Are you planning to update that thing soon?

iieklund says:

I assume you are using Opensource license?

The Opensource online content is mirrored by various hosts thus we’d need to know into which mirror your online installation is pointing into.

Could you try to figure out the mirror IP e.g. using WireShark and attach that information into bug report: https://bugreports.qt.io

With that information we can notify the mirror host about download issues.

HGH says:

A built-in error reporting and ability to change the mirror manually would be great to have in such case.

HGH says:

So if you are delivering 64bit MinGW libraries for 5.8. Why not just switch to gcc 6.0 as it will be mature by then?

J0hn says:

Mature? It will just have entered release, that not “mature” by any means, that is “fresh out the oven”…

Also this:

“Value range propagation now assumes that the this pointer of C++ member functions is non-null. This eliminates common null pointer checks but also breaks some non-conforming code-bases (such as Qt-5, Chromium, KDevelop)”

Philippe says:

Since the Qt Script module will be removed, do you provide a replacement somehow? Its interface with C++ is so easy…

@Philippe: Eventually Qt Qml, but Qt Script does still work.

Tham says:

Any plan to provide a cross-platform notification api?

Mihail Naydenov says:

Debugging support for std types would be great! If not pretty prints, at least overloads for qDebug. Thanks!

Kai Koehne Kai Koehne says:

Could you file a feature request with the std:: types you like to see supported in QDebug? Thanks!

jiraiya says:

QDateEdit using format dd/MM/yyyy almost unusable on android, please fix

Kai Koehne Kai Koehne says:

Please create bug report for this (if there is none yet) on http://bugreports.qt.io .

jiraiya says:

We do target 5.6, bit I suspect that this could be reproduce in 5.7 alpha release. Created https://bugreports.qt.io/browse/QTBUG-51909
