Hello Bob, The relevant changes to HSSFRegionUtil were done in this changelist: http://svn.apache.org/viewvc?view=rev&revision=682282 This change was prior to (and present in) release 3.2: http://svn.apache.org/viewvc/poi/tags/REL_3_2_FINAL/src/contrib/src/org/apache/poi/hssf/usermodel/contrib/HSSFRegionUtil.java
All the methods on HSSFRegionUtil that used Region have been deprecated and similar versions that use CellRangeAddress have been added. (Note that HSSFRegionUtil has twice as many methods now). The deprecated methods will hang around for one or two versions more. Please reply with details if the new methods aren't good replacements for the old ones or if there are bugs. regards, Josh
