Sure. To be honest I didn't notice any major issues with the previous firmware, other than the frequent 'low memory' messages. These seem to have gone away, and better memory management was mentioned in the (fairly vague) changelog.

Some changes I have noticed so far:

1. The status bar now has blue @ symbol next to the time when you have new emails.

2. The Transfer Manager has a different appearance, with a black background rather than white. It appears to use a Sheet component rather than a Dialog to display individual download status.

3. The theming of the MenuItem component has been changed when a dark theme is used (setting theme.inverted = true). Unfortunately my applications have two custom menu items (for sorting and searching), and the theming of these was broken. :/ It's my bad, really. I shouldn't have hardcoded the theming. I have already fixed them, and will issue updates within a day or two.

Nokia seem to be making an effort to remove any large white areas, probably to help maximise battery life.

I use my N950 almost exclusively for application deployment and testing. I don't even have a sim card in it, because for some reason it doesn't want to retain a 3g signal for any longer than a few minutes at a time (N8 and N900 are rock solid with the same sim in the same location). I might try again now that the firmware is updated. In any case, the device is serving the purpose for which it was intended, so I'm not too bothered.
