net-snmp5.3: Possible BUG in default debug print-outs

Hey,
 
in net-snmp-5.3 when I run 'snmpd -f' I get debug prints for tokes:
 
    - internal
    - verbose
    - trace
    - disman
    - snmpd ...
 
in version 5.2.1 is does not happen.
 
1) Are these now the default debug prints for when using -f option?
2) Is there an option argument I can pass to turn them off?
 
Thanks,
Erez.
