On the BitcoinCore web page, instructions are clear for the upgrade procedure:
“If you are running an older version, shut it down. Wait until it has
completely shut down … just copy over bitcoind / bitcoin-qt (on
Linux).”
Only 2 files are required to be copied into the Bitcoin installed folder.
Yet, when looking into the whole downloaded installation compressed file, once uncompressed, appears four folders, bin, include, lib, share. All four folders contain files of different size than the ones present in the previous equivalent folders already in the running Bitcoin version.
In all there are 12 different files for Bitcoin-Core 26 .vs. Bitcoin-Core 25.
The Question: Why instructions provided demand to simply copy 2 files where both versions contain 12 different files ? Why not renew with all 12 newer files ?
