I guess I'm becoming a dinosaur, and now I don't know where to find out about new FOSS stuff being developed, when new releases are out, etc.

I used to get it all on USENET and mailing lists, and then later on sourceforge.net and freshmeat.net. Now I track some things on https://freshcode.club/, but I don't see much that's 'fresh'. Maybe new updates, but not too many new packages. sourceforge still exists, but it doesn't seem current.

If I know about a project I'll follow it on GitHub, but I'm looking for a place to find out about new things that I didn't know I wanted yet.

tl;dr: Where can I watch to see promising new FOSS software projects?
