Yes, here are the differences:

• the payout now is 7 days, instead of 30 days,
• you can make more than 4 posts per day,
• you can upload directly to Steemit now, but it's still better to keep them small for dfast uploading and fast viewing,
• short posts seem to be preferred to long ones now.

I think everything else is still pretty true. Good luck on Steemit!
