The 32 and 64-bit Gentoo images have been brought up-to-date. Gentoo has never been release-centric and lately they seem to have moved away from labelled releases altogether. So I hope nobody minds if I dub this release "2010-0" to bring us into the future :-)
The 32-bit Gentoo images are now available in vmware's vmdk format, which can be run in the free vmware player (or other versions of vmware of course). Please see the complete list of Gentoo images here: http://stacklet.com/downloads/images/list/Gentoo
