Announcement

Whenever a new runtime branch is created or an old one is being EOL-ed an announcement should be made on https://discuss.kde.org/c/announcement/9

Qt Support

At a given point in time we will support the latest two Qt minor releases, e.g. 6.7 and 6.6.

End Of Life

Once a new Qt minor version is released we will wait one month for marking the previous -2 branch as EOL

Lifetime

This also gives around 10-12 months of support for each Qt 6.x branch.

Qt major version

This policy applies only within a major version of Qt, that is, Qt 5.x, Qt 6.x, Qt 7.x are supported independently of each-other in regards to Qt Support, End Of Life, etc.

Freedesktop SDK runtime

Each Qt based runtime will only target one Freedesktop SDK runtime. Exceptions might be made when a given minor Qt version reaches very long stable support like Qt 5.15

Corollary: If the release of a new Qt version and new Freedesktop SDK runtime are close in time we may wait a bit introducing the new Qt runtime so that it uses the new Freedesktop SDK runtime.
