How to Upgrade
==============
If you are running an older version, shut it down. Wait until it has
completely
shut down (which might take a few minutes in some cases), then run the
installer (on Windows) or just copy over `/Applications/Bitcoin-Qt` (on
macOS)
or `bitcoind`/`bitcoin-qt` (on Linux).
Upgrading directly from a version of Bitcoin Core that has reached its EOL
is
possible, but it might take some time if the data directory needs to be
migrated. Old
wallet versions of Bitcoin Core are generally supported.
Compatibility
==============
Bitcoin Core is supported and tested on operating systems using the
Linux Kernel 3.17+, macOS 13+, and Windows 10+. Bitcoin
Core should also work on most other Unix-like systems but is not as
frequently tested on them. It is not recommended to use Bitcoin Core on
unsupported systems.
