VirtualBox 1.5.0

InnoTek VirtualBox is a general-purpose full virtualizer for x86 hardware. Targeted at server, desktop and embedded use, it is now the only professional-quality virtualization solution that is also Open Source Software. Not only is VirtualBox an extremely feature rich, high performance product for enterprise customers, it is also the only professional solution that is freely available as Open Source Software under the terms of the GNU Public License (GPL). Presently, VirtualBox runs on Windows and Linux 32-bit hosts and supports a large number of guest operating systems including but not limited to Windows (NT 4.0, 2000, XP, Server 2003, Vista), DOS/Windows 3.x, Linux (2.4 and 2.6), and OpenBSD.

when i click on the download link i get:

Since I use Ubuntu (Linux) it automatically upgraded from 1.4.0 to 1.5.0 last night. This is the best free Virtualisation software around for Linux.

Virtual Box beats VirtualPC and VMWare hands down.

The fact that you can adjust the amt of video memory at all beats the others.
It is more stable and I am able to setup a new VM in minutes using ISOs.
I have XP, Server 2008, PC-BSD and 3 different Linux distros that I run regularly - many at the same time, all on a Vista Ultimate machine w/4GB. What I want to try now is to install a virtual Vista inside a Linux distro!

BTW, they even have a version for you freaky apple people (LOL!)
I can't wait until you can install OSx in a virtual machine though, that will be fantastic.

I checked last night and it was 1.4.0, then 9 hours later, 1.5.0!!! Amazing. Hopefully this time I can install on windows without it telling me I could damage my system (the idea makes me end install :P ).

Edit: Odd. The only place I can see a mention of 1.5.0 is the user manual change log. The website, and everything refers to 1.4.0. Any ideas why??
