[scribus] stable version for leopard

[SP]

Upto now I have been using 1.3.3.10 on my mac (Tiger 10.4.11)
My new box is an iMac with Leopard (10.5.6). (I shall soon update to 
snow leopard!)

which would be the stable version for this platform? I heard that it is 
1.3.5.1!!
Where do I find the stable version. On Sourceforge I could not locate 
the stable version.!!!

I tried 1.3.3.10 and due to some reason it does not work.

Thanks for any help

With best regards
