Qt 5.5 early look

 

Hi,

I've spent a bit of time with Qt 5.5 alpha since its release in March.
Here's the first screenshot of Ubuntu on it:

FTBFS bug fixers of maliit-framework, qtmir, unity8.

More information at https://wiki.ubuntu.com/Touch/QtTesting. WARNING:
Not for end-users of any kind, only for fixing bugs, anything can
break and the packaging is not proper. KDE Plasma 5 or Ubuntu SDK (Qt
Creator) don't work yet. Unity 8 on phone or desktop should be
testable.

At this point it's too early to talk about shipping Qt 5.5, and I
don't decide that. But what this partial alpha enables is starting to
file and fix bugs earlier than ever:
https://bugs.launchpad.net/bugs/+bugs?field.tag=qt5.5 - I've filed ~20
so far.

Upstream is 1.5+ months behind the schedule
(https://wiki.qt.io/Qt-5.5-release), so even though this early work is
useful, it's not necessarily going to be a fun ride to the feature
freeze again.

Looking beyond 5.5, I think it'd be nice to stay flexible about the Qt
version. If Qt 5.6 targets November, slips to mid-December like 5.4
did, we get .0 about ready January/February assuming no big
regressions and that's quite late for an LTS. The alternative to 5.6
would be to ship something like Qt 5.5.3 instead of the .0/.1
releases. Qt upstream has considered giving one of their release an
"LTS" status. If that'd happen to be 5.5, maybe it would make sense
for Ubuntu LTS too. But 5.6 would be a possibility as well, especially
if upstream would target and deliver nearer to October.
