Where are prior versions?

1.55, or whatever the current version is, is a no-go for me.

It’s fine, I’ll just go back to 1.5…but how do I get it? I can’t find it any where.

How come?
What is wrong with 1.55 compaired to earlier releases?

Previous versions : http://sourceforge.net/projects/volumio/files/Raspberry%20PI/
But what is wrong for you ?
