• removed Linux-only limitations
• Added UPDATER_MIN_VERSION and UPDATER_CHANNEL vars to help consolidate those for easier maintenance/testing
• tested on on darwin arm64: update itself, validate sig and checksum, update algod

all of these changes bring value, nice to see progress here!

I've tested these using https://github.com/algolucky/tests/tree/main/go-algorand/updater, others feel free to do the same.

[algobarb]

It looks fine to me. Maybe we should also have some devs review this so they are aware of these new changes coming?

revisit later
