The new version of NeoOffice is out. The current version is 3.2. According to their web page at http://www.neooffice.org/neojava/en/index.php there are updates to font support and support for Lion (OS X 10.7) when it comes out.
Their download page insists on a donation to the cause. Considering the quality of this product and the cost of a fully commercial product, for most people a donation would be justified.
Those who can not afford a donation can still download and use the older 3.1.2 version.
