Damn, I’ve been gone for too long. Same program, compiled with different versions:
Arduino 1.5
Program size: 26,396 bytes (used 92% of a 28,672 byte maximum)
Minimum Memory Usage: 1396 bytes (55% of a 2560 byte maximum)
Arduino 1.6
Program size: 22,638 bytes (used 79% of a 28,672 byte maximum)
Minimum Memory Usage: 1409 bytes (55% of a 2560 byte maximum)
I spent a lot of time optimizing the program to get it to fit in the available memory while working with v1.5. I am glad I did, I learned a lot about using true C++ data types versus using the Arduino built-in ones which is what allowed me to squeeze the program down. And now, I have extra room with v1.6. 
Time for a rehash, rebuilt, and project revival.
