I've installed 8rc1 and I've run into an issue. I didn't see anything in the change log, so I'll put it here.

The !BOX! variable that has been historically available doesn't seem to be supported with CONNECTIONTYPE POSTGIS any longer. For instance:

   DATA "geom from (
      select
         geom
      from sometable
      where st_intersects(geom, !BOX!)
   ) as sq using unique geom using srid=4269"

...will throw an error:

<?xml version='1.0' encoding="UTF-8" standalone="no" ?>
<!DOCTYPE ServiceExceptionReport SYSTEM "http://schemas.opengis.net/wms/1.1.1/exception_1_1_1.dtd";>
<ServiceExceptionReport version="1.1.1">
<ServiceException>
msDrawMap(): Image handling error. Failed to draw layer named &#39;wptsAll&#39;.
msPostGISLayerWhichShapes(): Query error. Failed to build query SQL.
msPostGISBuildSQL(): General error message. Failed to build SQL &#39;where&#39;.
</ServiceException>
</ServiceExceptionReport>

If I remove the !BOX! it will work.

Thanks!
Scott
