For the most part, it should appear as though nothing has changed. Don't fret! Since this is built on an entirely new system (front-end and back-end), we wanted to test what we have and are familiar with for a little before tossing in a bunch of new things.
Mostly what we're looking for are performance issues and major bugs ('reddit broke' messages, XSS issues, etc.). We've created a subreddit for bugs where you can submit bugs that you find.
Once things are tested, we'll begin transitioning to the new system and start adding on the new features.
Some things you should know:
- Search is better, but not quite where we'd like it.
- Some old features don't exist at the moment: friends, stats, recommendations, sharing, comment pagination. They're not gone for good, we just haven't put them back together yet.
- Tagging is built-in, though we haven't exposed it through the UI yet.
- Comments are improved, try them out.
UPDATE: Thank you, raldi, you're a bug-finding machine.
