I can confirm that 3.0.RC1 fixes some problems I was having with the PRE that is in feisty currently with reading a squid 2.6 created ufs cache.
So, if you release gutsy with 3.0.PRE6-1 that is in it currently, it will NOT work with a 2.6 created cache. Using 3.0.RC1 will work correctly.
Additionally, the release that's in feisty currently was also disconnecting CONNECT sessions which 3.0.RC1 does not.
Please consider upgrading to 3.0.RC1 for gutsy.
