[squid-users] Beta testers wanted for 3.2.0.1 - Changing 'workers' (from 1 to 2) is not supported and ignored

dear squid list,

i'd like to use the new 'worker' feature in squid-3.2
According to http://www.squid-cache.org/Versions/v3/3.2/cfgman/workers.html default is to have only one 'worker'.
Now I'd like to have at least two workers. Unfortunately it doesn't work

squid[32350]: WARNING: Changing 'workers' (from 1 to 2) is not supported and ignored

What am I doing wrong ? Any new compile option I ignored ?
