Plasma 6 coming to unstable

[Aurélien COUDERC <coucouf@debian.org>]

Dear fellow developers and Plasma users,

after some months living in experimental and lots of positive feedback, we're about to upload Plasma 6 to unstable.
The plans of the Qt / KDE team is to release Trixie with :
    - Qt 5 & 6
    - KDE Frameworks 5 aka KF5 (based on Qt 5) & KF6 (based on Qt6)
    - Plasma 6 (based on KF6 and Qt6)
    - KDE Gear applications of the moment. We expect to ship a mix of KF5 and KF6-based Gear applications depending on where upstream is with their porting effort of these mostly independent applications.

What we won’t be supporting for Trixie are Plasma 5 libraries, so if you maintain rdeps of Plasma 5 libraries now is time to port them to Plasma 6 or to remove them from testing. We’ve filed bugs for all the rdeps not in our team’s perimeter some weeks back [1]. We will be bumping their severity to RC in preparation the upload of Plasma 6 to unstable. We've tried our best to identify affected packages but we may have missed some so if you know your packages depend on Plasma and they're not in this list please do double check compatibility with Plasma 6.

There are cross-dependencies between some bits of Plasma, the accounts SSO stack, some KF5/6 libraries and some Gear apps, so expect some breakage in the online accounts functionality while the pieces are moving.

Also we currently don’t have a satisfying way of ensuring the entirety of Plasma migrates to testing synchronously, so when Plasma 6 packages start migrating to testing you’ll have to be extra careful with what your apt / Discover upgrades announce to avoid removing your desktop.


Happy hacking,
