Well its out and on the whole for a maintenance release I am quite pleased, some nice improvements and it seems to be working fine on our iPad2 and iPhone6.
What I am not happy is about is the update of our iPhone5. I basically hung at the slide to continue screen. No matter what I did, reboots restores etc, nothing could get it working except to setup as a new phone, not something I wanted to do.
Apple have suggested a fix on their support site but it did not work for me.
In the end the fix was to download iOS 8 and restore that then restore the data. So now I am back to OS8 on the iPhone5 until Apple come up with a fix.

To go back:
Step 1 – Backup your pictures! Even though you can’t get to your phone and use it you should still be able to backup your pictures
Step 2 – Download IOS 8.4.1 for your iPhone or iPad from this site –> https://ipsw.me/8.4.1
If you are confused which file to download check the model on back of your phone and use site below to determine the version you need.

The file was taking a while to download for my phone so I searched the filename on Google and downloaded from Mega.
Step 3 – Reboot phone into DFU mode – hold down power button and home button – when it reboots let go of power button – still hold home button
At this point it will ask you to connect your phone to iTunes – will have to connect phone to the computer.
Step 4 – Hold down the Option (Mac) or Shift (Windows) and and then click restore.
Step 5 – Browse to the 8.4.1 file you downloaded and select it. This should restore to the previous IOS version. Note: This will wipe phone.
Step 6 – Restore from backup. Hope that you backed up before attempting to update.
