Most things that were available then are still out there - incursions, exploration, escalations, etc.
Some new things are:
- the new player experience (AIR NPE and AIR Careers) so could be interesting to try that out with a new pilot.
- the Triglavian invasion/Edencom changes and the new Pochven area
- Abyssal Site running (related to Triglavian invasion)
Some updates for Faction Warfare are supposedly in the works, but may be a bit before we see the result.
You could also look in the general forum for post on EVE Pandora which is a new player-run method for creating missions and content, or check out Githany Red’s posts on New Eden Police Force for anti-ganking.
