So is Discord the place the place to be updated about what’s new in the Switch scene?

For Eden, yeah. Definitely. For Ryubing, no idea. I got permanently banned from their Discord for mentioning ''Steam Deck OLED'', lol. But you can usually find Eden's changelogs on their GitLab: Eden latest changelog. From the site, you can also get the latest version of Eden. So, enjoy lol.
