[Q] Update CWM from v 5.5.0.4 topic

Hi there!

I've just rooted my gt s7500 and i've installed the cwm recovery v5.5.0.4.
I am trying to install a new rom with this. But somehow, I saw that for the rom that I needed, I must have a newer cwm. My question is, how do I update from 5.5.0.4 to 6??

I've searched google and xda forum but I couldn't found the proper answer.

Thanks,
