Why did you stop support VMware ESXi 4.1 ?

Hi all,

I would like to ask if somebody tested the new version 10.5.2-3 with VMware ESXi 4.1?
We use only basic version, no clustering or similar advantages.....

Are there some internal calls the new functions of VMware 5.x or it is only administrative action?

The "line" 10.5 started to support these older ESXi 4.1 include 10.5.1-2. Why the support ended in the middle?

Thanx
