The development schedule for the 8.3 release is:
March 1, 2006
Initial community review of all major feature patches
April 1, 2006
Feature freeze, all patches must be submitted for review and
application
mid-May, 2006
All patches applied, beta testing begins
July, 2006
Release of 8.3.0
Patches that appear after appropriate dates are typically not applied
but held for the next major release.

<P>However, there are cases where a transactions needs to see rows
affected in previous parts of the transaction. This is accomplished
using a Command Counter. Incrementing the counter allows
transactions to be broken into pieces so each piece can see rows
modified by previous pieces. <I>CommandCounterIncrement()</I>
