We no longer read or write the legacy StarOffice file formats (files with extensions .sdw, .sdc, .sdd, etc.). Removal of this code makes the OpenOffice codebase easier to maintain. The legacy formats have never been the default format in any version of OpenOffice. Users with legacy StarOffice documents are advised to re-save them into ODF format (.odt, *.ods, *.odp, etc.) *before upgrading to Apache OpenOffice 4.0. This can be done using File - Wizards - Document Converter in OpenOffice 3.x. x OpenOffice 1.x files (*.sxw, *.sxc, *.sxi) are still supported.

The internal Python, used by default in the Windows and MacOS-X ports, has now been upgraded with version 2.7.5 which fixes hundreds of bugs and has important performance improvements but is still compatible with previous versions.
Support for system C++ STL
