	Some of you who have been around for a long time will know that we talked about replacing Havok1 a long time ago, and did not seem to get this project done, and finally went silent about it. After several false starts, we decided that it would be best to stop talking about the work, or making public commitments, until we were far closer to the goal, and we believe that we are finally at this point.		Some of you who have been around for a long time will know that we talked about replacing Havok1 a long time ago, and did not seem to get this project done, and finally went silent about it. After several false starts, we decided that it would be best to stop talking about the work, or making public commitments, until we were far closer to the goal, and we believe that we are finally at this point.

	For "quite some time" we worked to replace Havok1 with Havok2. After working on that project, we realized that we really should rework the interfaces for how Havok is integrated with Second Life. We realized that we needed to define an abstraction layer - a layer of code that would make it easier to do future physics engine migrations so that they don't take as much effort as this migration took, and to allow for more flexibility down the road. At this point Havok4 became a much more reasonable target than implementing based on a then-older release... and thus we set Havok4 as the target. This project has been significantly larger than any of us anticipated, however the good news is that we are now here, ready for beta testing, and ready to fix the last minute issues before we bring Havok4-based sims to the main grid!
