demofile newer than updated local repository copy of Angstrom ?


I am a little confused...

Looking here:
it seems that the demo files are based on Linux kernel 3.2.28.

After upgradeing my lokal copy of the git repository with
    git pull
    MACHINE=beaglebone ./ update

and building the kernel, this kernel is 3.2.23.

So it seems, that my update procedure, which I have verified
several time by searching the net, does something wrong.

'git branch' give me:
   * master

What I am doing wrong here?

Thank you very much in advance for any help!
Have a nice weekend!
Best regards,
