Change in parameters' order in prepared statement??

I recently updated the driver to the latest CVS version, and found a
change in the way parameters are handled.  Before, the first parameter
was 1, as in:

update.setInt(1,cbid);

But now it's 2, as in:

update.setInt(2,cbid);

I'm using only IN parameters to call a prepared SELECT. Is this the
correct behaviour? Is it going to stay this way?
