Oh i totally missed that meeting. That is unfortunate. I think staying on an old QT version brings many disadvantages, which have already been mentioned in this thread.
One argument is the security issue. I can’t evaluate it exactly, but continuing to use a version that hasn’t been supported for about 4 years can be dangerous.
QT has been developed further in the last years. Progress has been made in the area of execution speed and memory management (in addition to new modules/features).
There are two issues which, in my opinion, need to be improved about SFOS:
- QT version
- Make the closed source components of Sailfish open source.
I understand that a version upgrade can be difficult due to the license of QT and the contracts with Jolla’s customers. But I think that sometime in the near future the step of QT upgrade will be inevitable. I would really like to have a better communication with Jolla about this topic, especially about the pain points. Maybe there are some tasks, where the community can support Jolla.
