[cvsnt] cvs history -u

[zhuyunchuan]

I found the format of output of 'cvs history' changed while updated to
1.11.3b77a or newer.
Format of older version: (cvs history -a -D 2003-3-20 -z +0800)
O 2003-3-20 10:20 +0800 zhuyunchuan MG600X =MG600X <remote>/*
Format of newer version: (cvs history -a -e -D 2003-3-30 -z +0800)
C 2003-3-31 08:49 +0800 (null) AS6030_SNMP/src 1.4 <remote> == zhuyunchuan

I can only get the first info when I use "cvs history -u zhuyunchuan -e" 
, why?
