For now, we only see OpenOffice.org 3.4 Alpha Release mentioned at OpenOffice.org, but there are some exciting objectives being proposed for Beta, too. One of my own interests (see topic Format cells with engineering notation) is that first one. Oracle's OOo developers are discussing all of the ideas below and they may even "borrow" additional enhancements from the LibreOffice development team. LO is open source, after all.
- Add Engineering format to the Calc's Format > Cells > Numbers dialog
Add AltSearch functionality to Writer's standard Edit > Find & replace dialog
Allow user-specified date format in headers and footers
Implement SUMIFS, COUNTIFS, and IFERROR in Calc (like Excel)
User-customizible icons for OOo files
Implement Excel 2007 style multi-string value filter
Save Writer documents in several eBook formats
Standalone Impress presentations (view in web browser without having OpenOffice installed)
Correctly sort a range containing references to itself (fix for Issue 63781)
Ability to open PDF for editing with Writer
Automatic formula simplification in OOo Math
Add Calendar and Address Book components
Calculate derivatives and integrals of formulas in OOo Math
Update the database included with OOo (currently HSQLDB) to an Oracle database
Intelligent macro generator (watches what you do and creates macros to perform actions it sees frequently)
Add Tools > Language > Translate to Writer (web service, translated via Wikipedia)
