The most important bit being E7DF EE27 FF27 0994 versus E7DF E0E0 FF27 0994 (E27 or 0E0)
The original has an instruction:
7fd0: e7 df rcall .-50 ; 0x7fa0 <watchdogConfi\
g>
__asm__ __volatile__ (
7fd2: ee 27 eor r30, r30
7fd4: ff 27 eor r31, r31
7fd6: 09 94 ijmp
With the EE27 instruction being the "eor r30, r30" - an exclusive or with yourself is one way to clear the register.
The new version has "e0e0" instead, which is "ldi r30, 0" - which does the same thing (zero the register.) So you should be fine...
