Best guess based on previous updates: your old saves will not have the new features in previously-generated chunks, but post-patch chunks will have them. That is to say, you would have to go exploring to find biomes, or hellgates or fish if they work in that way.
Well certian things will require either a new save or for you to explore a new area.
fish should spawn in the water near you
torches will go out
you can craft lanterns
you will need to explore new areas for biomes
and depending on how portals work it changes:
if you craft them the changes will take effect
if you have to find them then you need to explore
if mobs drop them then changes should take effect.
The best part about this game is the first few days and I hope it gets challenging enough that I'll be able to start many many many new games!
You can't really generalise that point. For you that may be the best part. For others, they may enjoy the game when they are well established and feeling more at ease.
Personally, I'm going to keep an old world (for a while at least) and start at least one new one.
Wow, I'm so sorry I didn't add "The best part about this game FOR ME..."
Thank goodness you corrected me!!!!! You are so helpful!

Im guessing it works similar to this anyways
