GDAL/OGR 1.7.0

ALERT: The GDAL/OGR 1.7.0 release has been discovered to have a serious bug which results in all Erdas Imagine files (HFA driver) being generated in a way that is unreadable by non-GDAL software. Due to this bug, the GDAL/OGR project has retracted the 1.7.0 release, and has issued it's replacement with the 1.7.1 bug fix release. See http://trac.osgeo.org/gdal/ticket/3382 for details.
