As per summary, please stable version 1.24-r1, which has been in tree for over a month, and I've since used in production systems. @bass: please let me know if you wish to keep older versions in tree, given that 1.22 and former (i.e. all those that I don't maintain) are now end-of-life'd, and the current stable (1.11) is a very bad ebuild which I'd like to remove asap.
Damn me and thinking two things at once. It's UFDBGUARD, not squidguard, sorry.
x86 stable, closing (not sure why you're apparently not stabilizing this on amd64).
