Hello Marc, Thank you for your answer. > http://www.squid-cache.org/mail-archive/squid-users/200504/0087.html I already know that you normaly do not take pre-releases in production environments. Your answer doesn't really reply to my question as there were the indirect question when there may be a first stable release of Squid 3.0 available. I'm just asking because this really is the first time I saw pre-releases in an opensource project but after years of it sill no stable release. I think the way from pre to stable normaly takes only a few month :-) If not, the pre-releases aren't exactly those but more development stuff. Regards Julian Pawlowski
