I think the Discourse changes have already begun to be implemented as I see several differences in how the forum displays threads and posts. Most of the changes appear to be esthetic.
I found this disclaimer on the web:
“Discourse will no longer support Windows 7, and while basic functionality may continue, updates and stability are not guaranteed. Users are encouraged to upgrade to a newer operating system for full support.”
I think you’ll continue to have basic functionality for a while… however if you’ve tried Thorium or Supermium thorium vs supermium - compare differences and reviews? | LibHunt and they cause your AV to quarantine them, you can take a chance and whitelist them as safe.
