Can't Find Z10

I subscribed to S and I am checking out all the additional Z packages. However, I noticed that there is no Z10 in my set. How do I try this out?

Pardon me if this isn't the right place to ask this question

Judging from "What's new" page it seems that Z10 will be released with Zorro 1.81: http://manual.zorro-project.com/new.htm

thanks i'll be sure to use that source from now on
