It is official, OpenOffice.org 3.0 Beta version is available for download.
The feature list is here and you'll be glad to know that support for Microsoft 2007 file format (OOXML) is now a reality !
Also, OpenOffice.org for Mac is now an Aqua application that does not require the X11 windowing environment. Those of you who don't know what that means are blessed !
The stable version is planned for release in September. Although the free office suite is still not considered stable, it is stable enough for most of your non-mission critical work. I've been using test versions of 3.0 for a while now and I have been very pleased with it. I've noticed that it is significantly faster than NeoOffice at launch too.
Feel free to download it from here.
