Developing for iPhone 6/6+

Hi
I started my 2D game a month ago based on 5S as my native resolution. Now that 6 is out, I was wondering what I should do in terms of sprite sizes/cameras.

Do I use a camera native resolution at 1080 x 1920? Do I force a resolution? Should pixels per meter stay at 100?
If I use the figures above, will it get scaled down appropriately for iPhone5 and 4?

Thanks for your advice

It depends on your game. If you can "show more" of your scene, then you don't need to change anything and just have the override to "pixel perfect" and it'll just work.
You don't need to change pixels per meter for any reason.
