Summary

Basic text extractor for very old Excel formats such as Excel 4 (Biff4), and older Excel 5 and 95 formats
XML Signature support for XSSF, XWPF and XSLF (56836)
HSSF and XSSF support for getting existing Data Validations for a Sheet
HSSF and XSSF formula support for the PROPER function (57010)
XSLF support for adding slide notes (55164)

XSSF support for evaluating formula references to other Workbooks (56737)
HSSF and XSSF support for evaluating formulas with multi-sheet references, for functions that support that (55906)
HSSF and XSSF Workbooks are now Closeable, so you can call close() to explicitly free the file based resources when you're done (56537)
NPOIFS now fully supports writing, including streaming write, and in-place updating of existing entries. NPOIFSFileSystem now surpasses the old POIFSFileSystem in all cases.
XSSF Text Extraction support for Headers, Footers and Comments (56022 56023)

XWPF Change Tracking support (56075)

The interface org.apache.poi.xssf.eventusermodel.XSSFSheetXMLHandler.SheetContentsHandler has had two method signature changes: endRow() -> endRow(int) and cell(String,String) -> cell(String,String,Comment)
All security related changes from 3.10.1 (CVE-2014-3529 and CVE-2014-3574) are included in 3.11. Thanks to Stefan Kopf, Mike Boufford, Mohamed Ramadan, and Christian Schneider for their help with these.
Please note: You should use xmlbeans-2.6.jar (as shipped with this release) instead of the xmlbeans-2.3.jar version from old releases to work around CVE-2014-3574. If you have an alternate XML parser like Apache Xerces in classpath, be sure to use a recent version! Older versions are likely to break on setting required security features.
