I'm sure somebody will correct me if I'm wrong, but I think the main changes include: 1) the SMPng project. This basically makes it so that SMP machines can run the kernel on more than one CPU at a time. This should eventually increase performance on SMP machines. 2) The KSE project. This basically reworks how threaded processes are handled and introduces a form of kernel threading. It is not EXACTLY kernel threading, but to simplify the explanation, this is what I'm calling it. It'll basically improve the performance of threaded apps. 3) As far as I know, 5.0's kernel threads will be preempted. (This is basically a pre-empted kernel. Right now only userland processes can are using preempted multitasking) There are tons of other changes, but I think these are the major ones... maybe someone can add to this/correct me...
