<![CDATA[It's Qt 5.12 time.]]>It's been a long time coming, but we're finally merging Qt 5.12 into Ubuntu Touch.

This is a process that will take a few days. During that time, updates to the devel channel of Ubuntu Touch will be pinned to an older rootfs release. Changes to Android compatibility images will be shipped, but changes to packages in the system will not.

So, you will still see updates available on some devices (like the Nexus 5, Volla Phone...) but not on others (Bq E5, E4.5...). Don't be alarmed!

This is only a notification, no action is needed on your part. 🙂

My apps use SVG and they are displayed small unlike before.

At least on Puremaps the navigation is broken because of the screen turning off after a short while.

Dekko is using qbs and doing a few things a little differently though, so I'm not sure how to correctly update the quickflux dep there.

There are a few extra issues with the OnePlus 3 also, such as the camera, and lack of message bubbles in the messaging app.

Can you flash the device again with the installer?

Not sure if related, but the 196 update on my OnePlus3 just failed to install and now I am stuck at the boot logo with a broken install (error seems to have been: "couldn't load bitmap icon_error (error -7)" which is also shown in the ubports recovery now).

All the necessary PRs have been merged (there will still be more fixes to come as well though). We should have new devel channel images available for updating your devices soon.

Anyone who used ubports-qa to test the xenial_-_qt-5-12 and related branches should reset their devices by flashing again with the installer, or switching to rc channel in settings to get a full flash. Those branches are no longer valid. There's still a little rebase work needed for mainline and possibly android9 devices, but should be done soon.

That env var works for debugging on device as well, given you got Qt 5.12 installed there.

Anything using the Ubuntu Touch apt repositories will be problematic until Qt 5.12 transition is done.

Your device will almost certainly break currently if you do, requiring you to flash again with the installer.
