    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 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 data directory 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 10.15+, and Windows 7 and newer. 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.

    Notable changes

    P2P and network changes

    • A bitcoind node will no longer rumour addresses to inbound peers by default.
      They will become eligible for address gossip after sending an ADDR, ADDRV2,
      or GETADDR message. (#21528)

    • Before this release, Bitcoin Core had a strong preference to try to connect only to peers that listen on port 8333. As a result of that, Bitcoin nodes listening on non-standard ports would likely not get any Bitcoin Core peers connecting to them. This preference has been removed. (#23542)

    • Full support has been added for the CJDNS network. See the new option -cjdnsreachable and doc/cjdns.md (#23077)

    Fee estimation changes

    • Fee estimation now takes the feerate of replacement (RBF) transactions into
      account. (#22539)

    Rescan startup parameter removed

    The -rescan startup parameter has been removed. Wallets which require
    rescanning due to corruption will still be rescanned on startup.
    Otherwise, please use the rescanblockchain RPC to trigger a rescan. (#23123)

    Tracepoints and Userspace, Statically Defined Tracing support

    Bitcoin Core release binaries for Linux now include experimental tracepoints which
    act as an interface for process-internal events. These can be used for review,
    debugging, monitoring, and more. The tracepoint API is semi-stable. While the API
    is tested, process internals might change between releases requiring changes to the
    tracepoints. Information about the existing tracepoints can be found under
    doc/tracing.md and
    usage examples are provided in contrib/tracing/.

    Updated RPCs

    • The validateaddress RPC now returns an error_locations array for invalid
      addresses, with the indices of invalid character locations in the address (if
      known). For example, this will attempt to locate up to two Bech32 errors, and
      return their locations if successful. Success and correctness are only guaranteed
      if fewer than two substitution errors have been made.
      The error message returned in the error field now also returns more specific
      errors when decoding fails. (#16807)

    • The -deprecatedrpc=addresses configuration option has been removed. RPCs
      gettxout, getrawtransaction, decoderawtransaction, decodescript,
      gettransaction verbose=true and REST endpoints /rest/tx, /rest/getutxos,
      /rest/block no longer return the addresses and reqSigs fields, which
      were previously deprecated in 22.0. (#22650)
    • The getblock RPC command now supports verbosity level 3 containing transaction inputs’
      prevout information. The existing /rest/block/ REST endpoint is modified to contain
      this information too. Every vin field will contain an additional prevout subfield
      describing the spent output. prevout contains the following keys:

      • generated – true if the spent coins was a coinbase.
      • height
      • value
      • scriptPubKey
    • The top-level fee fields fee, modifiedfee, ancestorfees and descendantfees
      returned by RPCs getmempoolentry,getrawmempool(verbose=true),
      getmempoolancestors(verbose=true) and getmempooldescendants(verbose=true)
      are deprecated and will be removed in the next major version (use
      -deprecated=fees if needed in this version). The same fee fields can be accessed
      through the fees object in the result. WARNING: deprecated
      fields ancestorfees and descendantfees are denominated in sats, whereas all
      fields in the fees object are denominated in BTC. (#22689)

    • Both createmultisig and addmultisigaddress now include a warnings
      field, which will show a warning if a non-legacy address type is requested
      when using uncompressed public keys. (#23113)

    Changes to wallet related RPCs can be found in the Wallet section below.

    New RPCs

    • Information on soft fork status has been moved from getblockchaininfo
      to the new getdeploymentinfo RPC which allows querying soft fork status at any
      block, rather than just at the chain tip. Inclusion of soft fork
      status in getblockchaininfo can currently be restored using the
      configuration -deprecatedrpc=softforks, but this will be removed in
      a future release. Note that in either case, the status field
      now reflects the status of the current block rather than the next
      block. (#23508)

    Files

    • On startup, the list of banned hosts and networks (via setban RPC) in
      banlist.dat is ignored and only banlist.json is considered. Bitcoin Core
      version 22.x is the only version that can read banlist.dat and also write
      it to banlist.json. If banlist.json already exists, version 22.x will not
      try to translate the banlist.dat into json. After an upgrade, listbanned
      can be used to double check the parsed entries. (#22570)

    Updated settings

    • In previous releases, the meaning of the command line option
      -persistmempool (without a value provided) incorrectly disabled mempool
      persistence. -persistmempool is now treated like other boolean options to
      mean -persistmempool=1. Passing -persistmempool=0, -persistmempool=1
      and -nopersistmempool is unaffected. (#23061)

    • -maxuploadtarget now allows human readable byte units [k|K|m|M|g|G|t|T].
      E.g. -maxuploadtarget=500g. No whitespace, +- or fractions allowed.
      Default is M if no suffix provided. (#23249)

    • If -proxy= is given together with -noonion then the provided proxy will
      not be set as a proxy for reaching the Tor network. So it will not be
      possible to open manual connections to the Tor network for example with the
      addnode RPC. To mimic the old behavior use -proxy= together with
      -onlynet= listing all relevant networks except onion. (#22834)

    Tools and Utilities

    • Update -getinfo to return data in a user-friendly format that also reduces vertical space. (#21832)

    • CLI -addrinfo now returns a single field for the number of onion addresses
      known to the node instead of separate torv2 and torv3 fields, as support
      for Tor V2 addresses was removed from Bitcoin Core in 22.0. (#22544)

    Wallet

    • Descriptor wallets are now the default wallet type. Newly created wallets
      will use descriptors unless descriptors=false is set during createwallet, or
      the Descriptor wallet checkbox is unchecked in the GUI.

      Note that wallet RPC commands like importmulti and dumpprivkey cannot be
      used with descriptor wallets, so if your client code relies on these commands
      without specifying descriptors=false during wallet creation, you will need
      to update your code.

    • Newly created descriptor wallets will contain an automatically generated tr()
      descriptor which allows for creating single key Taproot receiving addresses.

    • upgradewallet will now automatically flush the keypool if upgrading
      from a non-HD wallet to an HD wallet, to immediately start using the
      newly-generated HD keys. (#23093)

    • a new RPC newkeypool has been added, which will flush (entirely
      clear and refill) the keypool. (#23093)

    • listunspent now includes ancestorcount, ancestorsize, and
      ancestorfees for each transaction output that is still in the mempool.
      (#12677)

    • lockunspent now optionally takes a third parameter, persistent, which
      causes the lock to be written persistently to the wallet database. This
      allows UTXOs to remain locked even after node restarts or crashes. (#23065)

    • receivedby RPCs now include coinbase transactions. Previously, the
      following wallet RPCs excluded coinbase transactions: getreceivedbyaddress,
      getreceivedbylabel, listreceivedbyaddress, listreceivedbylabel. This
      release changes this behaviour and returns results accounting for received
      coins from coinbase outputs. The previous behaviour can be restored using the
      configuration -deprecatedrpc=exclude_coinbase, but may be removed in a
      future release. (#14707)

    • A new option in the same receivedby RPCs, include_immature_coinbase
      (default=false), determines whether to account for immature coinbase
      transactions. Immature coinbase transactions are coinbase transactions that
      have 100 or fewer confirmations, and are not spendable. (#14707)

    GUI changes

    • UTXOs which are locked via the GUI are now stored persistently in the
      wallet database, so are not lost on node shutdown or crash. (#23065)

    • The Bech32 checkbox has been replaced with a dropdown for all address types, including the new Bech32m (BIP-350) standard for Taproot enabled wallets.

    Low-level changes

    RPC

    • getblockchaininfo now returns a new time field, that provides the chain tip time. (#22407)

    Tests

    • For the regtest network the activation heights of several softforks were
      set to block height 1. They can be changed by the runtime setting
      -testactivationheight=name@height. (#22818)
