SDFAT 1.0.16, ParticleSoftSerial 0.0.8

Firmware

I would appreciate the community’s help on this odd outcome:

I made an exact copy of a program. Before making any changes to it, I tried to compile it and ended up with errors related to SDFat and ParticleSerial libraries(please see below).

SDFAT-ParticleSoftSerial

I checked the library versions I was using on the old program (which continues to compile fine) and found the following:

  1. SDFat library used in new program (1.0.16), SDFat library used on old program (0.0.7).

  2. ParticleSoftLibrary library used in new program (0.0.8), ParticleSoftLibrary library used on old program ( (0.0.6).

What may be causing this and how can I use the older libraries?
