The HowTo and FAQ and a number of docs state things that are no longer true for 2.0. Such as support for internationalization which has progressed significantly, support for custom formats: I want to set a cell format (Data format of a cell) of a excel sheet as###,###,###.#### or ###,###,###.0000. Is it possible using POI ? HSSF does not yet support custom data formats, however, it should be a reasonably easy facillity to add and we'll gladly accept contributions in this area. These are the built in formats that it does support: http://jakarta.apache.org/poi/javadocs/javasrc/org/apache/poi/hssf/usermodel/HSSFDataFormat_java.html#HSSFDataFormat and otehr things... We just need to go clean these up before they start to rot and confuse.
We need to do this before final release
I believe that all docs DO reflect current state. Yegor
