Well there is one good reason why there is no up2date release for 4.16. It lost support for our compaq raid controler. I do not know if this happened with any others but this is a brand new server and they just added the support for it in the 4.02 release I belive it was. We are having alot of problems and were advised to install 4.16. Well turns out that it wasn't possible because of this.
