One of my favorite is that :The number of apps which can be loaded onto the Nano S at the same time can be raised to up to 18.  Other update improvements:
    Better screen lock management
    Full 24 words backup validation enforced
    Misc UX optimizations (faster device)
    Misc security improvements

It may look simple but many users experienced problems. In most cases it was ledger stuck on "update" screen! (STEP 5) If you also experienced same problems, you are lucky that you are here, because i will show how to fix it.
 As they state, ledger Manager is under massive load as tens of thousands users are trying to update in the same time. This generates some troubles on the flow. If you get stuck at one step. Just wait a few minutes and try again. But in many cases waiting does not help.. so if you have your device stuck on "update" screen, follow these steps:
1) Open device manager and check "human interface devices"
2) Find the device with a yellow warning sign. (it will be your Ledger).
3) Go to the "driver" tab and update device driver
4)Once the driver is updated successfully and there's no more yellow warning sign beside
5) Quit the Ledger Manager
6) Disconnect your Nano S
7)  launch Ledger Manager again 
8)  While holding the left button (at least 5 sec), connect the Nano S again
9) If you did everything right “Bootloader” should be displayed on your device’s screen and ledger manager app will continue installing!
