1. The auto-selection of the target unit you currently have highlighted was a huge time-saver for me. At one stage i had to go back to an older version to test something and immediately noticed it missing

2. Removed restriction of number of messages in MP. I think thats a big help, although I dont play MP much. Having to wait for one letter to be delivered before you could send another was a pain.
3. Facing command - 'change facing at destination' will work for static uniots and ones in motion. it's the new command, but the other command was left in because it is a version of the previous one, in case people liked that for specific tasks.
4. The waypoints command - so you will specify waypoints first, and then the 'move to map point' for your final destination. If no waypoints, then just the move to map point. This will remove the bug some people reported of a unit continuing to their destination before moving to the amended destination. It required separating waypoints and move commands.
5. The 'timebug' - I hope never to see it again. Fingers crossed.
