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 very old versions of Bitcoin Core or Knots is possible, but it might take some time if the data directory needs to be migrated. Old wallet versions of Bitcoin Knots are generally supported.
If you need to ensure your prior transaction mempool is preserved across the upgrade (usually you don't), be sure you upgrade to and open Knots 0.21.1 prior to upgrading to 22.0 or later.
Bitcoin Knots is supported on operating systems using the Linux kernel, macOS 10.15+, and Windows 7 and newer. It is not recommended to use Bitcoin Knots on unsupported systems.
-
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 Knots 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 Knots 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 now takes the feerate of replacement (RBF) transactions into account. (#22539)
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)
Bitcoin Knots 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/.
-
The
-deprecatedrpc=addresses
configuration option has been removed. RPCsgettxout
,getrawtransaction
,decoderawtransaction
,decodescript
,gettransaction verbose=true
and REST endpoints/rest/tx
,/rest/getutxos
,/rest/block
no longer return theaddresses
andreqSigs
fields, which were previously deprecated in 22.0. (#22650) -
The top-level fee fields
fee
,modifiedfee
,ancestorfees
anddescendantfees
returned by RPCsgetmempoolentry
,getrawmempool(verbose=true)
,getmempoolancestors(verbose=true)
andgetmempooldescendants(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 thefees
object in the result. WARNING: deprecated fieldsancestorfees
anddescendantfees
are denominated in sats, whereas all fields in thefees
object are denominated in BTC. (#22689) -
The return value of the
pruneblockchain
method had an off-by-one bug, returning the height of the block after the most recent pruned. This has been corrected, and it now returns the height of the last pruned block as documented. -
A new
require_checksum
option has been added to thederiveaddress
method to allow for specifying descriptors without first calculating a checksum for them. (#24162)
Changes to wallet related RPCs can be found in the Wallet section below.
-
Information on soft fork status has been moved from
getblockchaininfo
to the newgetdeploymentinfo
RPC which allows querying soft fork status at any block, rather than just at the chain tip. Inclusion of soft fork status ingetblockchaininfo
can currently be restored using the configuration-deprecatedrpc=softforks
, but this will be removed in a future release. Note that in either case, thestatus
field now reflects the status of the current block rather than the next block. (#23508) -
The
sendall
RPC spends specific UTXOs to one or more recipients without creating change. By default, thesendall
RPC will spend every UTXO in the wallet.sendall
is useful to empty wallets or to create a changeless payment from select UTXOs. When creating a payment from a specific amount for which the recipient incurs the transaction fee, continue to use thesubtractfeefromamount
option via thesend
,sendtoaddress
, orsendmany
RPCs. (#24118) -
A new
gettxspendingprevout
RPC has been added, which scans the mempool to find transactions spending any of the given outpoints. (#24408)
- On startup, the list of banned hosts and networks (via
setban
RPC) inbanlist.dat
is ignored and onlybanlist.json
is considered. Bitcoin Knots version 22.x is the only version that can readbanlist.dat
and also write it tobanlist.json
. Ifbanlist.json
already exists, version 22.x will not try to translate thebanlist.dat
into json. After an upgrade,listbanned
can be used to double check the parsed entries. (#22570)
-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 isM
if no suffix provided. (#23249)
-
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 ofonion
addresses known to the node instead of separatetorv2
andtorv3
fields, as support for Tor V2 addresses was removed from Bitcoin Knots in 22.0. (#22544)
-
Descriptor wallets are now the default wallet type. Newly created wallets will use descriptors unless
descriptors=false
is set duringcreatewallet
, or theDescriptor wallet
checkbox is unchecked in the GUI.Note that wallet RPC commands like
importmulti
anddumpprivkey
cannot be used with descriptor wallets, so if your client code relies on these commands without specifyingdescriptors=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) -
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) -
The following RPCs:
listtransactions
,gettransaction
andlistsinceblock
now include thewtxid
of the transaction. (#24198) -
The
listtransactions
,gettransaction
, andlistsinceblock
RPC methods now include a wtxid field (hash of serialized transaction, including witness data) for each transaction. -
A new
gettxspendingprevout
RPC has been added, which scans the mempool to find transactions spending any of the given outpoints. (#24408) -
The
fundrawtransaction
,send
, andwalletcreatefundedpsbt
RPC methods now acceptminconf
andmaxconf
options to limit selection of inputs to UTXOs with a range of blocks confirmed. The previousmin_conf
option which served the same purpose is deprecated and may be removed in a future version. (#22049) -
The
fundrawtransaction
RPC method accepts a newsegwit_inputs_only
option to limit inputs to only segwit UTXOs. (#25183)
-
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.
-
The network traffic graph can be switched between linear and non-linear views by clicking on the graph. Moving the mouse over the graph will show precise time and traffic info for a specific point. (gui#473, gui#492)
- 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)
