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 for older versions), then run the installer (on Windows) or just copy over /Applications/Bitcoin-Qt (on Mac) 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 datadir needs to be migrated. Old wallet versions of Bitcoin Core are generally supported.

Compatibility

Bitcoin Core is supported and extensively tested on operating systems using the Linux kernel, macOS 10.10+, and Windows 7 and newer. It is not recommended to use Bitcoin Core on unsupported systems.

Bitcoin Core should also work on most other Unix-like systems but is not as frequently tested on them.

From Bitcoin Core 0.17.0 onwards, macOS versions earlier than 10.10 are no longer supported, as Bitcoin Core is now built using Qt 5.9.x which requires macOS 10.10+. Additionally, Bitcoin Core does not yet change appearance when macOS "dark mode" is activated.

In addition to previously supported CPU platforms, this release's pre-compiled distribution provides binaries for the RISC-V platform.
