[Do I have to create a new world?]

Any new chunks in the nether will contain the new biomes, you can reset the nether so it's fully on 1.16.1

How to reset nether:
1 - go into the file manager on your panel
2 - get rid of the world_nether file
3 - restart your server

Oh, thank you, I got it

@jellz Wait, which one I have to delete?

Yes, that will only delete the nether world, your other worlds (Overworld, End, etc.) will stay the same

That's great, thank you!

New nether chunks will be generated as 1.16.1.

If you want to reset your entire nether world, you can do so 2 ways:

Deleting from in-game
1. Deleting in-game is easier, simply type the command "/del world world_nether"
2. The game will return saying "Deleted successfully" and the world will be gone.
After you delete the world, make a new portal and a new world with the 1.16.1 content will be on the world.

Deleting from the panel
1. Head over to the server you want to delete the world from and start it up
2. Once the server is online, go to the file manager and find the file called "world_nether"
3. After, click the bin that can be found in the top right of the file directory and enable deletion mode
4. Check the box next to the "world_nether" file and delete the world
After you delete the world, make a new portal and a new world with the 1.16.1 content will be on the world.

So it will delete JUST nether, not the entire world, right?

Guys, if I'm right 1.16 is already released. Do I have to create a new world if I didn't chunk nether?

[1.16 Nether update]

Do I have to create a new world for 1.16 if I haven't discovered nether yet?
