After V7.3 was released, there was only one interesting change in the V7.3 releases (in Nov 2001)

;               In the I/O post routines queue the IRP on the current CPU, if the
;               UCB$V_IOPOST_LOCAL bit is set.
;               Optimize the codeflow for the various flavours of COM(_STD)$POST
;               and COM(_STD)$POST_NOCNT to have the same prologue so they can
;               branch to a common code and are treated equally.

After that, there was a change made in Jan 2003 related to IA64 porting

;               Update COM_STD$POST and COM_STD$POST_NOCNT to correctly
;               obtain arguments for IA64.

and a change in Mar 2003 related to tracing and performance monitoring.

;               Add conditionalized code to call io_trace rtn
;               if PMS$GL_TDCBLK is enabled and there is a trace rtn.
