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 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
-----------------------
- Transactions of non-witness size 65 bytes and above are now allowed by mempool
and relay policy. This is to better reflect the actual afforded protections
against CVE-2017-12842 and open up additional use-cases of smaller
transaction sizes. (#26265)
New RPCs
--------
- The scanblocks RPC returns the relevant blockhashes from a set of
descriptors by
scanning all blockfilters in the given range. It can be used in
combination with
the getblockheader and rescanblockchain RPCs to achieve fast wallet
rescans. Note
that this functionality can only be used if a compact block filter index
(-blockfilterindex=1) has been constructed by the node. (#23549)
Updated RPCs
------------
- All JSON-RPC methods accept a new [named
parameter](https://github.com/bitcoin/bitcoin/blob/master/doc/JSON-RPC-interface.md#parameter-passing)
called `args` that can
contain positional parameter values. This is a convenience to allow some
parameter values to be passed by name without having to name every value. The
python test framework and `bitcoin-cli` tool both take advantage of this, so
for example:
```sh
bitcoin-cli -named createwallet wallet_name=mywallet load_on_startup=1
```
Can now be shortened to:
```sh
bitcoin-cli -named createwallet mywallet load_on_startup=1
```
- The `verifychain` RPC will now return `false` if the checks didn't fail,
but couldn't be completed at the desired depth and level. This could be due
to missing data while pruning, due to an insufficient dbcache or due to
the node being shutdown before the call could finish. (#25574)
- `sendrawtransaction` has a new, optional argument, `maxburnamount`
with a default value of `0`.
Any transaction containing an unspendable output with a value
greater than `maxburnamount` will
not be submitted. At present, the outputs deemed unspendable are
those with scripts that begin
with an `OP_RETURN` code (known as 'datacarriers'), scripts that
exceed the maximum script size,
and scripts that contain invalid opcodes.
- The `testmempoolaccept` RPC now returns 2 additional results within
the "fees" result:
"effective-feerate" is the feerate including fees and sizes of
transactions validated together if
package validation was used, and also includes any modified fees
from prioritisetransaction. The
"effective-includes" result lists the wtxids of transactions whose
modified fees and sizes were used
in the effective-feerate (#26646).
- `decodescript` may now infer a Miniscript descriptor under P2WSH
context if it is not lacking
information. (#27037)
- `finalizepsbt` is now able to finalize a transaction with inputs
spending Miniscript-compatible
P2WSH scripts. (#24149)
Changes to wallet related RPCs can be found in the Wallet section below.
Build System
------------
- The `--enable-upnp-default` and `--enable-natpmp-default` options
have been removed. If you want to use port mapping, you can
configure it using a .conf file, or by passing the relevant
options at runtime. (#26896)
Updated settings
----------------
- If the `-checkblocks` or `-checklevel` options are explicitly provided by the
user, but the verification checks cannot be completed due to an insufficient
dbcache, Bitcoin Core will now return an error at startup. (#25574)
- Ports specified in `-port` and `-rpcport` options are now validated
at startup.
Values that previously worked and were considered valid can now
result in errors. (#22087)
- Setting `-blocksonly` will now reduce the maximum mempool memory
to 5MB (users may still use `-maxmempool` to override). Previously,
the default 300MB would be used, leading to unexpected memory usage
for users running with `-blocksonly` expecting it to eliminate
mempool memory usage.
As unused mempool memory is shared with dbcache, this also reduces
the dbcache size for users running with `-blocksonly`, potentially
impacting performance.
- Setting `-maxconnections=0` will now disable `-dnsseed`
and `-listen` (users may still set them to override).
Changes to GUI or wallet related settings can be found in the GUI or
Wallet section below.
New settings
------------
- The `shutdownnotify` option is used to specify a command to execute
synchronously
before Bitcoin Core has begun its shutdown sequence. (#23395)
Wallet
------
- The `minconf` option, which allows a user to specify the minimum number
of confirmations a UTXO being spent has, and the `maxconf` option,
which allows specifying the maximum number of confirmations, have been
added to the following RPCs in #25375:
- `fundrawtransaction`
- `send`
- `walletcreatefundedpsbt`
- `sendall`
- Added a new `next_index` field in the response in `listdescriptors` to
have the same format as `importdescriptors` (#26194)
- RPC `listunspent` now has a new argument `include_immature_coinbase`
to include coinbase UTXOs that don't meet the minimum spendability
depth requirement (which before were silently skipped). (#25730)
- Rescans for descriptor wallets are now significantly faster if compact
block filters (BIP158) are available. Since those are not constructed
by default, the configuration option "-blockfilterindex=1" has to be
provided to take advantage of the optimization. This improves the
performance of the RPC calls `rescanblockchain`, `importdescriptors`
and `restorewallet`. (#25957)
- RPC `unloadwallet` now fails if a rescan is in progress. (#26618)
- Wallet passphrases may now contain null characters.
Prior to this change, only characters up to the first
null character were recognized and accepted. (#27068)
- Address Purposes strings are now restricted to the currently known
values of "send",
"receive", and "refund". Wallets that have unrecognized purpose
strings will have
loading warnings, and the `listlabels` RPC will raise an error if an
unrecognized purpose
is requested. (#27217)
- In the `createwallet`, `loadwallet`, `unloadwallet`, and
`restorewallet` RPCs, the
"warning" string field is deprecated in favor of a "warnings" field that
returns a JSON array of strings to better handle multiple warning messages and
for consistency with other wallet RPCs. The "warning" field will be fully
removed from these RPCs in v26. It can be temporarily re-enabled during the
deprecation period by launching bitcoind with the configuration option
`-deprecatedrpc=walletwarningfield`. (#27279)
- Descriptor wallets can now spend coins sent to P2WSH Miniscript
descriptors. (#24149)
GUI changes
-----------
- The "Mask values" is a persistent option now. (gui#701)
- The "Mask values" option affects the "Transaction" view now, in
addition to the
"Overview" one. (gui#708)
REST
----
- A new `/rest/deploymentinfo` endpoint has been added for fetching various
state info regarding deployments of consensus changes. (#25412)
Binary verification
----
- The binary verification script has been updated. In previous releases it
would verify that the binaries had been signed with a single "release key".
In this release and moving forward it will verify that the binaries are
signed by a _threshold of trusted keys_. For more details and
examples, see:
https://github.com/bitcoin/bitcoin/blob/master/contrib/verify-binaries/README.md
(#27358)
Low-level changes
=================
RPC
---
- The JSON-RPC server now rejects requests where a parameter is
specified multiple
times with the same name, instead of silently overwriting earlier
parameter values
with later ones. (#26628)
- RPC `listsinceblock` now accepts an optional `label` argument
to fetch incoming transactions having the specified label. (#25934)
- Previously `setban`, `addpeeraddress`, `walletcreatefundedpsbt`, methods
allowed non-boolean and non-null values to be passed as boolean parameters.
Any string, number, array, or object value that was passed would be treated
as false. After this change, passing any value except `true`, `false`, or
`null` now triggers a JSON value is not of expected type error. (#26213)

==============
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.
Notice of new option for transaction replacement policies
=========================================================
This version of Bitcoin Core adds a new `mempoolfullrbf` configuration
option which allows users to change the policy their individual node
will use for relaying and mining unconfirmed transactions. The option
defaults to the same policy that was used in previous releases and no
changes to node policy will occur if everyone uses the default.
Some Bitcoin services today expect that the first version of an
unconfirmed transaction that they see will be the version of the
transaction that ultimately gets confirmed---a transaction acceptance
policy sometimes called "first-seen".
The Bitcoin Protocol does not, and cannot, provide any assurance that
the first version of an unconfirmed transaction seen by a particular
node will be the version that gets confirmed. If there are multiple
versions of the same unconfirmed transaction available, only the miner
who includes one of those transactions in a block gets to decide which
version of the transaction gets confirmed.
Despite this lack of assurance, multiple merchants and services today
still make this assumption.
There are several benefits to users from removing this *first-seen*
simplification. One key benefit, the ability for the sender of a
transaction to replace it with an alternative version paying higher
fees, was realized in [Bitcoin Core 0.12.0][] (February 2016) with the
introduction of [BIP125][] opt-in Replace By Fee (RBF).
Since then, there has been discussion about completely removing the
first-seen simplification and allowing users to replace any of their
older unconfirmed transactions with newer transactions, a feature called
*full-RBF*. This release includes a `mempoolfullrbf` configuration
option that allows enabling full-RBF, although it defaults to off
(allowing only opt-in RBF).
Several alternative node implementations have already enabled full-RBF by
default for years, and several contributors to Bitcoin Core are
advocating for enabling full-RBF by default in a future version of
Bitcoin Core.
As more nodes that participate in relay and mining begin enabling
full-RBF, replacement of unconfirmed transactions by ones offering higher
fees may rapidly become more reliable.
Contributors to this project strongly recommend that merchants and services
not accept unconfirmed transactions as final, and if they insist on doing
so,
to take the appropriate steps to ensure they have some recourse or plan for
when their assumptions do not hold.

Notable changes
===============
P2P and network changes
- - -----------------------
- - - To address a potential denial-of-service, the logic to download
headers
from peers
has been reworked. This is particularly relevant for nodes starting up
for the
first time (or for nodes which are starting up after being offline for a
long time).
Whenever headers are received from a peer that have a total chainwork
that is either
less than the node's `-minimumchainwork` value or is sufficiently below
the work at
the node's tip, a "presync" phase will begin, in which the node will
download the
peer's headers and verify the cumulative work on the peer's chain, prior
to storing
those headers permanently. Once that cumulative work is verified to be
sufficiently high,
the headers will be redownloaded from that peer and fully validated and
stored.
This may result in initial headers sync taking longer for new nodes
starting up for
the first time, both because the headers will be downloaded twice, and
because the effect
of a peer disconnecting during the presync phase (or while the node's
best headers chain has less
than `-minimumchainwork`), will result in the node needing to use the
headers presync mechanism
with the next peer as well (downloading the headers twice, again).
(#25717)
- - - With I2P connections, a new, transient address is used for each
outbound
connection if `-i2pacceptincoming=0`. (#25355)
Updated RPCs
- - ------------
- - - The `-deprecatedrpc=softforks` configuration option has been removed.
The
RPC `getblockchaininfo` no longer returns the `softforks` field, which was
previously deprecated in 23.0. (#23508) Information on soft fork status is
now only available via the `getdeploymentinfo` RPC.
- - - The `deprecatedrpc=exclude_coinbase` configuration option has been
removed.
The `receivedby` RPCs (`listreceivedbyaddress`, `listreceivedbylabel`,
`getreceivedbyaddress` and `getreceivedbylabel`) now always return results
accounting for received coins from coinbase outputs, without an option to
change that behaviour. Excluding coinbases was previously deprecated in
23.0.
(#25171)
- - - The `deprecatedrpc=fees` configuration option has been removed. The
top-level
fee fields `fee`, `modifiedfee`, `ancestorfees` and `descendantfees` are
no
longer returned by RPCs `getmempoolentry`, `getrawmempool(verbose=true)`,
`getmempoolancestors(verbose=true)` and
`getmempooldescendants(verbose=true)`.
The same fee fields can be accessed through the `fees` object in the
result.
The top-level fee fields were previously deprecated in 23.0. (#25204)
- - - The `getpeerinfo` RPC has been updated with a new `presynced_headers`
field,
indicating the progress on the presync phase mentioned in the
"P2P and network changes" section above.
Changes to wallet related RPCs can be found in the Wallet section below.
New RPCs
- - --------
- - - The `sendall` RPC spends specific UTXOs to one or more recipients
without creating change. By default, the `sendall` 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 the `subtractfeefromamount` option via the
`send`, `sendtoaddress`, or `sendmany` RPCs. (#24118)
- - - A new `gettxspendingprevout` RPC has been added, which scans the
mempool to find
transactions spending any of the given outpoints. (#24408)
- - - The `simulaterawtransaction` RPC iterates over the inputs and outputs
of the given
transactions, and tallies up the balance change for the given wallet.
This can be
useful e.g. when verifying that a coin join like transaction doesn't
contain unexpected
inputs that the wallet will then sign for unintentionally. (#22751)
Updated REST APIs
- - -----------------
- - - The `/headers/` and `/blockfilterheaders/` endpoints have been updated
to use
a query parameter instead of path parameter to specify the result count.
The
count parameter is now optional, and defaults to 5 for both endpoints.
The old
endpoints are still functional, and have no documented behaviour change.
For `/headers`, use
`GET /rest/headers/<BLOCK-HASH>.<bin|hex|json>?count=<COUNT=5>`
instead of
`GET /rest/headers/<COUNT>/<BLOCK-HASH>.<bin|hex|json>` (deprecated)
For `/blockfilterheaders/`, use
`GET
/rest/blockfilterheaders/<FILTERTYPE>/<BLOCK-HASH>.<bin|hex|json>?count=<COUNT=5>`
instead of
`GET
/rest/blockfilterheaders/<FILTERTYPE>/<COUNT>/<BLOCK-HASH>.<bin|hex|json>`
(deprecated)
(#24098)
Build System
- - ------------
- - - Guix builds are now reproducible across architectures (x86_64 &
aarch64). (#21194)
New settings
- - ------------
- - - A new `mempoolfullrbf` option has been added, which enables the
mempool
to
accept transaction replacement without enforcing BIP125 replaceability
signaling. (#25353)
Wallet
- - ------
- - - The `-walletrbf` startup option will now default to `true`. The
wallet will now default to opt-in RBF on transactions that it creates.
(#25610)
- - - The `replaceable` option for the `createrawtransaction` and
`createpsbt` RPCs will now default to `true`. Transactions created
with these RPCs will default to having opt-in RBF enabled. (#25610)
- - - The `wsh()` output descriptor was extended with Miniscript support.
You
can import Miniscript
descriptors for P2WSH in a watchonly wallet to track coins, but you can't
spend from them using
the Bitcoin Core wallet yet.
You can find more about Miniscript on the [reference website](
https://bitcoin.sipa.be/miniscript/). (#24148)
- - - The `tr()` output descriptor now supports multisig scripts through the
`multi_a()` and
`sortedmulti_a()` functions. (#24043)
- - - To help prevent fingerprinting transactions created by the Bitcoin
Core
wallet, change output
amounts are now randomized. (#24494)
- - - The `listtransactions`, `gettransaction`, and `listsinceblock`
RPC methods now include a wtxid field (hash of serialized transaction,
including witness data) for each transaction. (#24198)
- - - The `listsinceblock`, `listtransactions` and `gettransaction` output
now contain a new
`parent_descs` field for every "receive" entry. (#25504)
- - - A new optional `include_change` parameter was added to the
`listsinceblock` command.
- - - RPC `getreceivedbylabel` now returns an error, "Label not found
in wallet" (-4), if the label is not in the address book. (#25122)
Migrating Legacy Wallets to Descriptor Wallets
- - ---------------------------------------------
An experimental RPC `migratewallet` has been added to migrate Legacy
(non-descriptor) wallets to
Descriptor wallets. More information about the migration process is
available in the
[documentation](
https://github.com/bitcoin/bitcoin/blob/master/doc/managing-wallets.md#migrating-legacy-wallets-to-descriptor-wallets
).
GUI changes
- - -----------
- - - A new menu item to restore a wallet from a backup file has been added
(gui#471).
- - - Configuration changes made in the bitcoin GUI (such as the pruning
setting,
proxy settings, UPNP preferences) are now saved to `<datadir>/settings.json`
file rather than to the Qt settings backend (windows registry or unix
desktop
config files), so these settings will now apply to bitcoind, instead of
being
ignored. (#15936, gui#602)
- - - Also, the interaction between GUI settings and `bitcoin.conf` settings
is
simplified. Settings from `bitcoin.conf` are now displayed normally in the
GUI
settings dialog, instead of in a separate warning message ("Options set in
this
dialog are overridden by the configuration file: -setting=value"). And these
settings can now be edited because `settings.json` values take precedence
over
`bitcoin.conf` values. (#15936)
Low-level changes
=================
RPC
- - ---
- - - The `deriveaddresses`, `getdescriptorinfo`, `importdescriptors` and
`scantxoutset` commands now
accept Miniscript expression within a `wsh()` descriptor. (#24148)
- - - The `getaddressinfo`, `decodescript`, `listdescriptors` and
`listunspent` commands may now output
a Miniscript descriptor inside a `wsh()` where a `wsh(raw())` descriptor
was previously returned. (#24148)
