Trying to understand all these firmware versions got OTA updating
I have a Gpy and looking through the firmwares, I can't figure out what all these release types mean. I have these two links
the first one has 1.20.2.r4 as the latest but has elf files? The second link is from the OTA docs but doesnt even have 1.20.2.r4 but has 1.20.2.rc10 tar files instead with a bunch of bin files inside of it. What's the difference between an elf file and all the bin files inside the second link? Which bin file would i need to use for OTA? What about "r" vs "rc"? why are the version in the release tab in github different from the versions in the gPy firmware link? It's not clear which version I'm supposed to update to.
There's also this link https://docs.pycom.io/advance/downgrade/ ? whats the difference between pygate and pybytes? the versions don't seem to match up here either... the latest version there is 1.20.2.rc11. So far I have three different links with 3 different "latest versions" and different file types.
