Hi Roland,

Just so that there is no misunderstanding Qt 5.15.2 release stays available for all users, it is just the upcoming LTS phase patch releases that will be commercial only. In essence for the open-source users Qt 5.15 is similar to Qt 5.13 and Qt 5.14 (non-LTS releases).

that's some brilliant timing, given that no actual qt 6 release even
exists yet. (yeah, 6.0 is a joke given that you intend to break binary
compat in 6.1 - that's the wisdom of linking r&d's bonus payments to
release dates even for major versions).

Yes, it would have made sense that the Qt Company waits for all modules to be available in Qt 6 before dropping the 5.15 open support...

I cannot express how much I agree to this. Qt6 has half of the modules required by my project not yet available, so upgrading is not possible. On the other hand, 5.15 LTS is closed for the open source users - this is quite a heavy restriction for me since my project is non-profit and open source. Buying a commercial license is not an option.
Yes I'm aware that I'm a small fish in a large pond and QtC won't care about my contributions or me as a developer using Qt since there is no profit to make with me. On the other hand, I will carefully think about using Qt again in future projects or recommend it to other people.
This is not a complaint. Its your business and your rules. I'm just trying to express the thoughts of a bigger but usally silent group of open source/non-profit users which are directly impacted by this.
