It has just been reported at gullfoss, that there is a new dev build release of openoffice 3 (this would be developer snapshot build DEV300_m16).
In addition to bringing us one step closer to the much expected OOo version 3, this dev build can be installed side by side to the “regular” OOo release, for someone adventurous enough to try new and exciting things. In addition, there is a 64-bit version for the people who like to run on the 64-bit way of life.
Although the release link does not say much, the 64-bit version is there along with the 32-bit version. It can be downloaded from many servers around the world.
