I'm running XBian 20150210-4 on an rPi-1 model B

I notice there's newer xbian installs and was wondering what is the upgrade procedure?
Note: The Sticky thread refers to making sure I read the FAQ which contains nothing about upgrading.

Any clear instruction would be great.
Thanks
Martin

from within xbian config, in Kodi GUI under Programs>XBian-Config or from ssh
