The OpenOffice.org Community is pleased to announce that the public beta release of OpenOffice.org 3.0 is now available. This beta release is made available to allow a broad user base to test and evaluate the next major version of OpenOffice.org, but is not recommended for production use at this stage.

If you are a regular user of OpenOffice.org, here's a great opportunity to help us make the next release the best ever.
What's new in OpenOffice.org 3.0?

The most immediately visible change to OpenOffice.org 3.0 is the new "Start Centre", new fresh-looking icons, and a new zoom control in the status bar. A closer look shows that 3.0 has a myriad of new features. Notable Calc improvements include a new solver component; support for spreadsheet collaboration through workbook sharing; and an increase to 1024 columns per sheet. Writer has an improved notes feature and displays of multiple pages while editing. There are numerous Chart enhancements, and an improved crop feature in Draw and Impress.
界面有所更新
Behind the scenes, OpenOffice.org 3.0 will support the upcoming OpenDocument Format (ODF) 1.2 standard, and is capable of opening files created with MS-Office 2007 or MS-Office 2008 for Mac OS X (.docx, .xlsx, .pptx, etc.). This is in addition to read and write support for the MS-Office binary file formats (.doc, .xls, .ppt, etc.).
可以支持MS-Office 2007文档了。
OpenOffice.org 3.0 will be the first version to run on Mac OS X without X11, with the look and feel of any other Aqua application. It introduces partial VBA support to this platform. In addition, OpenOffice.org 3.0 integrates well with the Mac OS X accessibility APIs, and thus offers better accessibility support than many other Mac OS X applications.
