Users are strongly advised to upgrade to this version.
ACE-00-02-00-beta2 fixes the single version folder bug in ACE-00-02-00-beta. Apparently, single version folders cannot be browsed/opened when given a "HEAD" tag. See Savanna http://savannah.cern.ch/bugs/?42101
It also fixes a problem with the validation of UInt32 fields.
The critical UChar bug in ACE-00-01-xx was fixed in ACE-00-02-00-beta1.
