Do you have advice on versions to use of mig / gnumach / hurd?

Currently, build-many-glibcs.py uses (by default) release versions of most 
components other than glibc itself, release branches for gcc / binutils.  
Should the most recent releases from ftp.gnu.org of mig / gnumach / hurd 
be used for building current glibc for Hurd, or is it preferable or 
necessary to use newer development versions of those components?
