Release Notes -- Apache POI -- Version 3.8

Introduction
------------

Apache POI is well-known in the Java field as a library for reading and
writing Microsoft Office file formats, such as Excel, PowerPoint, Visio and
Word. See http://poi.apache.org/ for more details

Apache POI 3.8 is an incremental feature release based on and
compatible with earlier POI 3.8-beta* releases. POI 3.8 is considered
stable and recommended for production use.

Release highlights:

* NPOIFS:  NIO driven API to read OLE2 filesystems with low memory footprint.
* SXSSF:  a low-memory footprint  API built on top of XSSF that can be
used when very large spreadsheets have to be produced, and heap space
is limited
* poi-excelant: Ant tasks for running POI against a workbook
* Supported evaluation of new Excel formulas:
IRR,NPV,MROUND,VAR,VARP,CLEAN,CHAR,ADDRESS,HOUR,MINUTE,SECOND,RATE,WORKDAY,NETWORKDAYS,SUMIFS,RANK
* XSLF usermodel API:  POI's implementation of the PowerPoint 2007
OOXML (.xlsx) file format. XSLF provides a rich usermodel API and a
PPTX2PNG utility to export slides to images.
* WordToFO, WordToHtml and WordToText converters: utilities to export
MS Word .doc files into XSL-FO, html and text files. Output from
WordToFO can be used to convert .doc files to pdf using Apache FOP.

Other notable changes:
* Numerous improvements and refactorings in HWPF, Java API for MS Word
.doc files: support for reading
  footnotes, endnotes and bookmarks, improved support for hadlings
tables, paragraphs, text runs and much more...
* Initial support for charts in XSSF
