Abode officially announced that Flash will be deprecated at the end of 2020 (3 years from now)
Announcement here: https://blogs.adobe.com/conversations/2017/07/adobe-flash-update.html
While Flash will still work after 2020, it won't get new features from Adobe except for security and OS compatibility.
For us, that's not a big change, it's not like Adobe was adding new features that we care about. Security and compatibility are the only changes to Flash that I personally care about, anyway, and those will continue even past 2021.
All this is is another sign that Flash is a dying platform, which we already knew.
Of course, WarLight's already moving away from Flash, and will likely be Flash-free long before 2020 anyway.
