 16  How to Upgrade
 17  ==============
 18  
 19  If you are running an older version, shut it down. Wait until it has completely
 20  shut down (which might take a few minutes in some cases), then run the
 21  installer (on Windows) or just copy over `/Applications/Bitcoin-Qt` (on macOS)
 22  or `bitcoind`/`bitcoin-qt` (on Linux).
 23  
 24  Upgrading directly from a version of Bitcoin Core that has reached its EOL is
 25  possible, but it might take some time if the data directory needs to be migrated. Old
 26  wallet versions of Bitcoin Core are generally supported.
 27  
 28  Running Bitcoin Core binaries on macOS requires self signing.
 29  ```
 30  cd /path/to/bitcoin-28.x/bin
 31  xattr -d com.apple.quarantine bitcoin-cli bitcoin-qt bitcoin-tx bitcoin-util bitcoin-wallet bitcoind test_bitcoin
 32  codesign -s - bitcoin-cli bitcoin-qt bitcoin-tx bitcoin-util bitcoin-wallet bitcoind test_bitcoin
 33  ```
 34  
 35  Compatibility
 36  ==============
 37  
 38  Bitcoin Core is supported and extensively tested on operating systems
 39  using the Linux Kernel 3.17+, macOS 11.0+, and Windows 7 and newer. Bitcoin
 40  Core should also work on most other UNIX-like systems but is not as
 41  frequently tested on them. It is not recommended to use Bitcoin Core on
 42  unsupported systems.

 44  Notable changes
 45  ===============
 46  
 47  ### P2P
 48  
 49  - When the `-port` configuration option is used, the default onion listening port will now
 50    be derived to be that port + 1 instead of being set to a fixed value (8334 on mainnet).
 51    This re-allows setups with multiple local nodes using different `-port` and not using `-bind`,
 52    which would lead to a startup failure in v28.0 due to a port collision.
 53  
 54    Note that a `HiddenServicePort` manually configured in `torrc` may need adjustment if used in
 55    connection with the `-port` option.
 56    For example, if you are using `-port=5555` with a non-standard value and not using `-bind=...=onion`,
 57    previously Bitcoin Core would listen for incoming Tor connections on `127.0.0.1:8334`.
 58    Now it would listen on `127.0.0.1:5556` (`-port` plus one). If you configured the hidden service manually
 59    in torrc now you have to change it from `HiddenServicePort 8333 127.0.0.1:8334` to `HiddenServicePort 8333
 60    127.0.0.1:5556`, or configure bitcoind with `-bind=127.0.0.1:8334=onion` to get the previous behavior.
