The much awaited OpenOffice.org 2.0 was released on 20 Oct, 2005.
OpenOffice.org natively supports the internationally standardised OpenDocument format, which several countries, as well as the U.S. state of Massachusetts, have established as the default for office documents. It is available in 36 languages (more promised) and as usual runs natively on GNU/Linux, Windows, Sun Solaris, Mac OS X and more. This new OpenDocument format prevents vendor lock-in and can be opened by any office application.
In addition to OpenDocument format, it has a new database module, improved PDF support, a superior spreadsheet module, enhanced Desktop integration and many more features.

So, will the new OpenOffice2.0 be a serious competitor to MS Office and what will be the answer to the OpenDocument Format? We have to wait and watch.
