Main differences between OM4 and OM5

[Aaron Hepp]

Is there a link or page that references the major differences between 
the different OM version OM4 vs OM5.  I was just wondering what the 
major changes will be as I was looking to start testing the OM5 on a 
separate platform and was just looking to see what changes/improvements 
were made over the previous package.

Thank you.
