Since December 2020 is near more details about the end of Flash support are showing up. One thing might be from special importance:
From January 1st 2021 you won't be able to run any Flash content on your computer.
It is described like a self destrucion mode: "Adobe will be removing Flash Player download pages from its site and Flash-based content will be blocked from running in Adobe Flash Player after the EOL Date." So it is no option to just ignore some security warnings and continue using an old Flash Player plugin. For the SP-Studio this means the current version won't be accessable anymore after December 31st, even if I keep it online.
There is hope that third party develeopers will find a way to run Flash content in your browser with a new plugin. There is tons of beloved Flash content on the internet, and it would be a shame to loose it all. So I believe clever people are already working on this. But right now I don't know if and when such tools will be available. If you find anything about this topic you can share it here. I will keep the Flash version of the SP-Studio online just in case, even after the new SP-Studio is launched. But... well... It's best to prepare for the worst case.
