filesystem type in new installer

[Michael]

Hello,

What are the valid filesystem types in Partition Editor?
Installer gives two examples: freebsd-ufs and freebsd-swap. I guess that 
I can use freebsd-zfs but what are the others? And is that list 
accessible from the installer itself (some kind of help system) or 
should I look in external documentation?

It's in the news that it supports geli, zfs and others but I don't see 
any of these options in the installer. Where should I look?
