Particle update command

I'm a bit curious as to why Particle Dev will compile to a default version different than what's considered the default for "particle update".

That would be surprising when you are using the most recent version of CLI (currently 1.18.0) too

Also, I'm wondering if there's a way to know what system firmware Particle Dev is compiling against before actually doing a compile.

You can have a look in Particle Build (Web IDE) or you just build and use particle binary inspect on resulting binary.
Or look in the Firmware Update Thread or on Tags · particle-iot/device-os · GitHub
