OpenOffice.org 3.0 can import Office 2007 OOXML files that have extensions such as .docx, .xlsx, and .pptx. OpenOffice.org does not yet feature the ability to save into these, though. Therefore, users will need to save into another supported format.
The writer component of the suite can now display multiple pages side-by-side, and the Calc spreadsheets component supports as many as 1024 columns (up from the previously supported 256). The Impress presentation component has also been updated with the ability to insert tables with ease. Performance is not among the improvements the suite can claim, however, as the new 3.0 release is the same in that area, if not a little slower.
Hopefully their website is back up by now…
