I didn't see this mentioned in the patch preview notes, but I hope it is there. Since I generally game in 1-2 hour sessions, I save and restart from saved games frequently. I have noticed the following problems with the saved games when you restart one:
1) It shows the pop-up screen welcoming my new civilzation to the galaxy, as if I was starting a new game.
2) It takes me to my research tree and home planet as if I was starting a new game.
3) All production (military, social and research) ceases to exist for one turn - nothing is produced in the turn after you hit the 'Turn' button after restoring from a saved game. This is very noticeable by looking at the timeline graph of manufacturing - it drops to 0 for myself and the AI. Over a long game, I can count how many times I restored from a save game by seeing the downward spikes in production.
4) Ships that moved before the save can move after restoring the save (haven't confirmed if this is 100% or just sometimes).
5) In the turn AFTER the 'no production turn', any ships or improvements built do not create a GNN news event allowing you to go to the planet to change production, OR the green/blue icons that appear down the right side of the screen that allow you to click to go to the planet, or right-click to launch the ship.
Most of these are annoyances and don't kill game play, but a fix for them would be greatly appreciated, and allow me to lose my 'fear' of needing to save a game and restore later (sometimes I just alt-tab out and let it run for hours in the background while I work on other things).
