To sum up, no idea how much we can help with 5.9 transition and what's

>From the Fosdem discussion, I feel like there is no big technical issue.
There was message that majority of SFOS core components already has branches
prepared for Qt 5.9. Issue with transition is licensing - more Qt components
was switched from LGPLv2.1 license to LGPLv3 [1]. If I understand it
correctly, LGPLv2 guarantees you as a user that you will get source code for
the library and you should be able to update library without application
modification - it allows proprietary applications to link shared Qt
libraries... But this second right is not mentioned explicitly. It is fixed in
LGPLv3 that guarantee to user that have to be possible to replace libraries.
This is not problem for SFOS itself, when you can get root access just by one
click. But for some Jolla partners, that want to create certified devices for
governments, this right may be a problem. Noone mention specific companies,
but it is clear that Jolla needs approval from their partners first...</pre>

<p>I really hope they finally decide to just got with GPLv3, as it's
not just Qt, but many</p>
<p>important system libraries, that are stuck on ancient pre-GPLv3
versions. Many of those libraries</p>
<p>are likely no longer maintained by upstream, which long ago moved
to taking care of the new GPLv3</p>
<p>licensed codebase instead.<br>
