[rules-users] What the.... is happening?

Sorry guys, but I can't understand why u released 4.0.5 a couple of weeks ago, then u suddenly released a brand new "4.0.6" release few days ago (which I promptly downloaded) and now u put back again the "4.0.4"....???.... *Why???* What is the stable one???? Does the svn is working?? Should we build from repository or shouldn't we? Looking forward to hearing any news on this matter.... Thank you anyway. Bye. Massimiliano
