new filesystem improvements in 6.0-RELEASE, require newfs?

[Nathan Vidican]

Most notably amongst the improvements/additions to 6.0-RELEASE, are those in the 
filesystem area. In performing a system upgrade, does one need to newfs/format a 
given partition with a new file system to make use of these optimizations, or is 
  the bonus simply in the kernel/filesystem support and sticking with the 
current UFS2 partition (5.3-RELEASE/amd64) will step-up to it?
