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 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 0.17.0 onwards, macOS <10.10 is no longer supported. 0.17.0 is
built using Qt 5.9.x, which doesn't support versions of macOS older than
10.10. Additionally, Bitcoin Core does not yet change appearance when
macOS "dark mode" is activated.

Users running macOS Catalina may need to "right-click" and then choose "Open"
to open the Bitcoin Core .dmg. This is due to new signing requirements
imposed by Apple, which the Bitcoin Core project does not yet adhere too.

Notable changes

New user documentation

• Reduce memory (https://github.com/bitcoin/bitcoin/blob/master/doc/reduce-memory.md)
    suggests configuration tweaks for running Bitcoin Core on systems with
    limited memory. (#16339 (https://github.com/bitcoin/bitcoin/pull/16339))

New RPCs

• getbalances returns an object with all balances (mine,
  untrusted_pending and immature). Please refer to the RPC help of
  getbalances for details. The new RPC is intended to replace
  getbalance, getunconfirmedbalance, and the balance fields in
  getwalletinfo.  These old calls and fields may be removed in a
    future version. (#15930 (https://github.com/bitcoin/bitcoin/pull/15930), #16239 (https://github.com/bitcoin/bitcoin/pull/16239))
  
• setwalletflag sets and unsets wallet flags that enable or disable
    features specific to that existing wallet, such as the new
  avoid_reuse feature documented elsewhere in these release notes.
    (#13756 (https://github.com/bitcoin/bitcoin/pull/13756))
  
• getblockfilter gets the BIP158 filter for the specified block.  This
    RPC is only enabled if block filters have been created using the
  -blockfilterindex configuration option. (#14121 (https://github.com/bitcoin/bitcoin/pull/14121))
  

New settings

• -blockfilterindex enables the creation of BIP158 block filters for
    the entire blockchain.  Filters will be created in the background and
    currently use about 4 GiB of space.  Note: this version of Bitcoin
    Core does not serve block filters over the P2P network, although the
    local user may obtain block filters using the getblockfilter RPC.
    (#14121 (https://github.com/bitcoin/bitcoin/pull/14121))

Updated settings

• whitebind and whitelist now accept a list of permissions to
    provide peers connecting using the indicated interfaces or IP
    addresses.  If no permissions are specified with an address or CIDR
    network, the implicit default permissions are the same as previous
    releases.  See the bitcoind -help output for these two options for
    details about the available permissions. (#16248 (https://github.com/bitcoin/bitcoin/pull/16248))
  
• Users setting custom dbcache values can increase their setting slightly
    without using any more real memory.  Recent changes reduced the memory use
    by about 9% and made chainstate accounting more accurate (it was underestimating
    the use of memory before).  For example, if you set a value of "450" before, you
    may now set a value of "500" to use about the same real amount of memory. (#16957 (https://github.com/bitcoin/bitcoin/pull/16957))
  

Updated RPCs

Note: some low-level RPC changes mainly useful for testing are described in the
Low-level Changes section below.

• sendmany no longer has a minconf argument.  This argument was not
    well-specified and would lead to RPC errors even when the wallet's
    coin selection succeeded.  Users who want to influence coin selection
    can use the existing -spendzeroconfchange, -limitancestorcount,
  -limitdescendantcount and -walletrejectlongchains configuration
    arguments. (#15596 (https://github.com/bitcoin/bitcoin/pull/15596))
  
• getbalance and sendtoaddress, plus the new RPCs getbalances and
  createwallet, now accept an "avoid_reuse" parameter that controls
    whether already used addresses should be included in the operation.
    Additionally, sendtoaddress will avoid partial spends when
  avoid_reuse is enabled even if this feature is not already enabled
    via the -avoidpartialspends command line flag because not doing so
    would risk using up the "wrong" UTXO for an address reuse case.
    (#13756 (https://github.com/bitcoin/bitcoin/pull/13756))
  
• RPCs which have an include_watchonly argument or includeWatching option now default to true for watch-only
    wallets. Affected RPCs are: getbalance, listreceivedbyaddress, listreceivedbylabel, listtransactions,
  listsinceblock, gettransaction, walletcreatefundedpsbt, and fundrawtransaction. (#16383 (https://github.com/bitcoin/bitcoin/pull/16383))
  
• listunspent now returns a "reused" bool for each output if the
    wallet flag "avoid_reuse" is enabled. (#13756 (https://github.com/bitcoin/bitcoin/pull/13756))
  
• getblockstats now uses BlockUndo data instead of the transaction
    index, making it much faster, no longer dependent on the -txindex
    configuration option, and functional for all non-pruned blocks.
    (#14802 (https://github.com/bitcoin/bitcoin/pull/14802))
  
• utxoupdatepsbt now accepts a descriptors parameter that will fill
    out input and output scripts and keys when known. P2SH-witness inputs
    will be filled in from the UTXO set when a descriptor is provided that
    shows they're spending segwit outputs.  See the RPC help text for full
    details. (#15427 (https://github.com/bitcoin/bitcoin/pull/15427))
  
• sendrawtransaction and testmempoolaccept no longer accept a
  allowhighfees parameter to fail mempool acceptance if the
    transaction fee exceeds the value of the configuration option
  -maxtxfee.  Now there is a hardcoded default maximum feerate that
    can be changed when calling either RPC using a maxfeerate parameter.
    (#15620 (https://github.com/bitcoin/bitcoin/pull/15620))
  
• getmempoolancestors, getmempooldescendants, getmempoolentry, and
  getrawmempool no longer return a size field unless the
    configuration option -deprecatedrpc=size is used.  Instead a new
  vsize field is returned with the transaction's virtual size
    (consistent with other RPCs such as getrawtransaction). (#15637 (https://github.com/bitcoin/bitcoin/pull/15637))
  
• getwalletinfo now includes a scanning field that is either false
    (no scanning) or an object with information about the duration and
    progress of the wallet's scanning historical blocks for transactions
    affecting its balances. (#15730 (https://github.com/bitcoin/bitcoin/pull/15730))
  
• gettransaction now accepts a third (boolean) argument verbose. If
    set to true, a new decoded field will be added to the response containing
    the decoded transaction. This field is equivalent to RPC decoderawtransaction,
    or RPC getrawtransaction when verbose is passed. (#16185 (https://github.com/bitcoin/bitcoin/pull/16185), #16866 (https://github.com/bitcoin/bitcoin/pull/16866), #16873 (https://github.com/bitcoin/bitcoin/pull/16873))
  
• createwallet accepts a new passphrase parameter.  If set, this
    will create the new wallet encrypted with the given passphrase.  If
    unset (the default) or set to an empty string, no encryption will be
    used. (#16394 (https://github.com/bitcoin/bitcoin/pull/16394))
  
• getchaintxstats RPC now returns the additional key of
  window_final_block_height. (#16695 (https://github.com/bitcoin/bitcoin/pull/16695))
  
• getmempoolentry now provides a weight field containing the
    transaction weight as defined in BIP141. (#16647 (https://github.com/bitcoin/bitcoin/pull/16647))
  
• The getnetworkinfo and getpeerinfo commands now contain a new field with decoded network service flags. (#16786 (https://github.com/bitcoin/bitcoin/pull/16786))
  
• getdescriptorinfo now returns an additional checksum field
    containing the checksum for the unmodified descriptor provided by the
    user (that is, before the descriptor is normalized for the
  descriptor field). (#15986 (https://github.com/bitcoin/bitcoin/pull/15986))
  
• joinpsbts now shuffles the order of the inputs and outputs of the resulting
    joined PSBT. Previously, inputs and outputs were added in the order PSBTs were
    provided. This made it easy to correlate inputs to outputs, representing a
    privacy leak. (#16512 (https://github.com/bitcoin/bitcoin/pull/16512))
  
• walletcreatefundedpsbt now signals BIP125 Replace-by-Fee if the
  -walletrbf configuration option is set to true. (#15911 (https://github.com/bitcoin/bitcoin/pull/15911))
  

GUI changes

• The GUI wallet now provides bech32 addresses by default.  The user may change the address type
    during invoice generation using a GUI toggle, or the default address
    type may be changed with the -addresstype configuration option.
    (#15711 (https://github.com/bitcoin/bitcoin/pull/15711), #16497 (https://github.com/bitcoin/bitcoin/pull/16497))
  
• In 0.18.0, a ./configure flag was introduced to allow disabling BIP70 support in the GUI (support was enabled by default). In 0.19.0, this flag is now <strong>disabled</strong> by default. If you want to compile Bitcoin Core with BIP70 support in the GUI, you can pass --enable-bip70 to ./configure. (#15584 (https://github.com/bitcoin/bitcoin/pull/15584))
  

Deprecated or removed configuration options

• -mempoolreplacement is removed, although default node behavior
    remains the same.  This option previously allowed the user to prevent
    the node from accepting or relaying BIP125 transaction replacements.
    This is different from the remaining configuration option
  -walletrbf. (#16171 (https://github.com/bitcoin/bitcoin/pull/16171))

Deprecated or removed RPCs

• bumpfee no longer accepts a totalFee option unless the
    configuration parameter deprecatedrpc=totalFee is specified.  This
    parameter will be fully removed in a subsequent release. (#15996 (https://github.com/bitcoin/bitcoin/pull/15996))
  
• bumpfee has a new fee_rate option as a replacement for the deprecated totalFee. (#16727 (https://github.com/bitcoin/bitcoin/pull/16727))
  
• generate is now removed after being deprecated in Bitcoin Core 0.18.
    Use the generatetoaddress RPC instead. (#15492 (https://github.com/bitcoin/bitcoin/pull/15492))
  

P2P changes

• BIP 61 reject messages were deprecated in v0.18. They are now disabled
    by default, but can be enabled by setting the -enablebip61 command
    line option.  BIP 61 reject messages will be removed entirely in a
    future version of Bitcoin Core. (#14054 (https://github.com/bitcoin/bitcoin/pull/14054))
  
• To eliminate well-known denial-of-service vectors in Bitcoin Core,
    especially for nodes with spinning disks, the default value for the
  -peerbloomfilters configuration option has been changed to false.
    This prevents Bitcoin Core from sending the BIP111 NODE_BLOOM service
    flag, accepting BIP37 bloom filters, or serving merkle blocks or
    transactions matching a bloom filter.  Users who still want to provide
    bloom filter support may either set the configuration option to true
    to re-enable both BIP111 and BIP37 support or enable just BIP37
    support for specific peers using the updated -whitelist and
  -whitebind configuration options described elsewhere in these
    release notes.  For the near future, lightweight clients using public
    BIP111/BIP37 nodes should still be able to connect to older versions
    of Bitcoin Core and nodes that have manually enabled BIP37 support,
    but developers of such software should consider migrating to either
    using specific BIP37 nodes or an alternative transaction filtering
    system. (#16152 (https://github.com/bitcoin/bitcoin/pull/16152))
  
• By default, Bitcoin Core will now make two additional outbound connections that are exclusively used for block-relay.  No transactions or addr messages will be processed on these connections. These connections are designed to add little additional memory or bandwidth resource requirements but should make some partitioning attacks more difficult to carry out. (#15759 (https://github.com/bitcoin/bitcoin/pull/15759))
  

Miscellaneous CLI Changes

• The testnet field in bitcoin-cli -getinfo has been renamed to
  chain and now returns the current network name as defined in BIP70
    (main, test, regtest). (#15566 (https://github.com/bitcoin/bitcoin/pull/15566))

Low-level changes

RPC

• getblockchaininfo no longer returns a bip9_softforks object.
    Instead, information has been moved into the softforks object and
    an additional type field describes how Bitcoin Core determines
    whether that soft fork is active (e.g. BIP9 or BIP90).  See the RPC
    help for details. (#16060 (https://github.com/bitcoin/bitcoin/pull/16060))
  
• getblocktemplate no longer returns a rules array containing CSV
    and segwit (the BIP9 deployments that are currently in active
    state). (#16060 (https://github.com/bitcoin/bitcoin/pull/16060))
  
• getrpcinfo now returns a logpath field with the path to
  debug.log. (#15483 (https://github.com/bitcoin/bitcoin/pull/15483))
  

Tests

• The regression test chain enabled by the -regtest command line flag
    now requires transactions to not violate standard policy by default.
    This is the same default used for mainnet and makes it easier to test
    mainnet behavior on regtest. Note that the testnet still allows
    non-standard txs by default and that the policy can be locally
    adjusted with the -acceptnonstdtxn command line flag for both test
    chains. (#15891 (https://github.com/bitcoin/bitcoin/pull/15891))

Configuration

• A setting specified in the default section but not also specified in a
    network-specific section (e.g. testnet) will now produce an error
    preventing startup instead of just a warning unless the network is
    mainnet.  This prevents settings intended for mainnet from being
    applied to testnet or regtest. (#15629 (https://github.com/bitcoin/bitcoin/pull/15629))
  
• On platforms supporting thread_local, log lines can be prefixed with
    the name of the thread that caused the log. To enable this behavior,
    use -logthreadnames=1. (#15849 (https://github.com/bitcoin/bitcoin/pull/15849))
  

Network

• When fetching a transaction announced by multiple peers, previous versions of
    Bitcoin Core would sequentially attempt to download the transaction from each
    announcing peer until the transaction is received, in the order that those
    peers' announcements were received.  In this release, the download logic has
    changed to randomize the fetch order across peers and to prefer sending
    download requests to outbound peers over inbound peers. This fixes an issue
    where inbound peers could prevent a node from getting a transaction.
    (#14897 (https://github.com/bitcoin/bitcoin/pull/14897), #15834 (https://github.com/bitcoin/bitcoin/pull/15834))
  
• If a Tor hidden service is being used, Bitcoin Core will be bound to
    the standard port 8333 even if a different port is configured for
    clearnet connections.  This prevents leaking node identity through use
    of identical non-default port numbers. (#15651 (https://github.com/bitcoin/bitcoin/pull/15651))
  

Mempool and transaction relay

• Allows one extra single-ancestor transaction per package.  Previously,
    if a transaction in the mempool had 25 descendants, or it and all of
    its descendants were over 101,000 vbytes, any newly-received
    transaction that was also a descendant would be ignored.  Now, one
    extra descendant will be allowed provided it is an immediate
    descendant (child) and the child's size is 10,000 vbytes or less.
    This makes it possible for two-party contract protocols such as
    Lightning Network to give each participant an output they can spend
    immediately for Child-Pays-For-Parent (CPFP) fee bumping without
    allowing one malicious participant to fill the entire package and thus
    prevent the other participant from spending their output. (#15681 (https://github.com/bitcoin/bitcoin/pull/15681))
  
• Transactions with outputs paying v1 to v16 witness versions (future
    segwit versions) are now accepted into the mempool, relayed, and
    mined.  Attempting to spend those outputs remains forbidden by policy
    ("non-standard").  When this change has been widely deployed, wallets
    and services can accept any valid bech32 Bitcoin address without
    concern that transactions paying future segwit versions will become
    stuck in an unconfirmed state. (#15846 (https://github.com/bitcoin/bitcoin/pull/15846))
  
• Legacy transactions (transactions with no segwit inputs) must now be
    sent using the legacy encoding format, enforcing the rule specified in
    BIP144.  (#14039 (https://github.com/bitcoin/bitcoin/pull/14039))
  

Wallet

• When in pruned mode, a rescan that was triggered by an importwallet,
  importpubkey, importaddress, or importprivkey RPC will only fail
    when blocks have been pruned. Previously it would fail when -prune
    has been set.  This change allows setting -prune to a high value
    (e.g. the disk size) without the calls to any of the import RPCs
    failing until the first block is pruned. (#15870 (https://github.com/bitcoin/bitcoin/pull/15870))
  
• When creating a transaction with a fee above -maxtxfee (default 0.1
    BTC), the RPC commands walletcreatefundedpsbt and
  fundrawtransaction will now fail instead of rounding down the fee.
    Be aware that the feeRate argument is specified in BTC per 1,000
    vbytes, not satoshi per vbyte. (#16257 (https://github.com/bitcoin/bitcoin/pull/16257))
  
• A new wallet flag avoid_reuse has been added (default off). When
    enabled, a wallet will distinguish between used and unused addresses,
    and default to not use the former in coin selection.  When setting
    this flag on an existing wallet, rescanning the blockchain is required
    to correctly mark previously used destinations.  Together with "avoid
    partial spends" (added in Bitcoin Core v0.17.0), this can eliminate a
    serious privacy issue where a malicious user can track spends by
    sending small payments to a previously-paid address that would then
    be included with unrelated inputs in future payments. (#13756 (https://github.com/bitcoin/bitcoin/pull/13756))
  

Build system changes

• Python &gt;=3.5 is now required by all aspects of the project. This
    includes the build systems, test framework and linters. The previously
    supported minimum (3.4), was EOL in March 2019. (#14954 (https://github.com/bitcoin/bitcoin/pull/14954))
  
• The minimum supported miniUPnPc API version is set to 10. This keeps
    compatibility with Ubuntu 16.04 LTS and Debian 8 libminiupnpc-dev
    packages. Please note, on Debian this package is still vulnerable to
  CVE-2017-8798 (https://security-tracker.debian.org/tracker/CVE-2017-8798)
    (in jessie only) and
  CVE-2017-1000494 (https://security-tracker.debian.org/tracker/CVE-2017-1000494)
    (both in jessie and in stretch). (#15993 (https://github.com/bitcoin/bitcoin/pull/15993))

@achow101 do we have a magnet link for 0.19.0.1?

Added it.

cool


as usual, this:

magnet:?xt=urn:btih:436859e8dddf4d8bd22d9ecc826139b6749a9a4a (magnet:?xt=urn:btih:436859e8dddf4d8bd22d9ecc826139b6749a9a4a)

will download over Bittorrent using the DHT only. Less censorable (and more private) because it's decentralized 8)

Cheers all!

:)

Just to check, the pinned topic at the top of the board is still the 0.18.1 release.  Should this topic not be pinned instead?

//EDIT:  All sorted, I see.  :)

Did you mean https://bitcoin.org/bin/bitcoin-core-0.19.0.1/ (https://bitcoin.org/bin/bitcoin-core-0.19.0.1/) ?

Anyway, ty for the info!! let's update!

No, I did not. bitcoincore.org is the website for the Bitcoin Core project. Bitcoin.org happens to also host binaries for Bitcoin Core, but bitcoincore.org is still the official place to get downloads.

ok, my mistake.

The cert's been renewed already. It uses Let's Encrypt so it's free. I think Matt just forgot to renew it (something about not wanting to install certbot on the web server so it's renewed manually).

Any reason when i check under info tab its showing under memory pool both current number of transactions  and memory usage as N/A?  :-\

a known bug

https://github.com/bitcoin/bitcoin/pull/17427 (https://github.com/bitcoin/bitcoin/pull/17427) is the fix

How many time to download with 20mbit adsl all bitcoin transactions?

The synchronisation time depends also on your hardware since your CPU is verifying each downloaded block. It's really difficult to predict the needed time. It usually takes 1-3 days.

Some time ago I upgraded bitcoin v0.18 to v0.19.0.1.
I downloaded it from https://bitcoin.org/en/download (Mac OS version), but Bitdefender antivirus detected Bitcoin-Qt as a threat.
Is this just a "False Positive" Antivirus Problem?

https://i.imgur.com/A53PNgZ.png

Yes. As long as you have checked the hashes and PGP signature of the download, it is legitimate. Antivirus often falsely flag Bitcoin Core as malware because it contains mining logic.

Thank you, I have checked and verified the PGP Signatures.

And put Bitcoin-Qt into the list of files excepted from scanning on Bitdefender.

https://i.imgur.com/YRTqMSW.png

in my experience it's more often because it contains the string "wallet.dat" these days.

Just recently upgraded to latest version and the US English or simply English language options are gone! Selecting Default gives me some English mixed with partially translated Latvian and best working option now is UK English.

Why there is not one option for one language? I know there is like 7+ Spanish options and English in various parts of world have different dialects. But why? And if so, why there is no at least 4 versions of Russian (for each country where Russian have official status) or U.S. East Coast, U.S. West Coast and Texass English?

Looks like it was removed, probably accidentally. I've opened a PR (https://github.com/bitcoin/bitcoin/pull/17886) to restore it.

Default will use your systems local language settings, which I guess is Latvian. It looks like there isn't a full Latvian translation yet, so Core will fallback to using the original English strings.

Because there are multiple regional dialects. Bitcoin Core uses [Transifex](https://www.transifex.com/bitcoin/bitcoin/) for translations which allows people to translate for a ton of languages and their regional dialects. Some of those people will choose to translate for the various dialects, so those translations end up in the software.

Either because no one has bothered with translating for those dialects, or Transifex does not give those dialects as options to translate to.

I need to say I waited long for set Bech32 as standart adress definition in Bitcoin core and hope it will solve some problems in next hype

I am running my own full node as suggested. Can somebody explain to me why solo mining in not allowed directly from Bitcoin Core as it was possible in the early days.
I understand that it is not going to mine any blocks but the PC is already on and connected to the network - no reason not to allow solo mining and support Bitcoin at the same time.

Because mining using CPU/GPU won't do anything. It would be a waste of resources.

You can either buy ASIC if you want to get into mining or just continue running a full node, that helps the network (https://bitcoin.org/en/full-node#what-is-a-full-node) as well.

Still, I also do not understand why the CPU mining was disabled. Users must have a choice and removing option what once was available is evil. This is exactly like removing PRIME95 stress test option because of waste of resources. Some people still have free electricity or want to use computer as a heat source.

You can either buy ASIC if you want to get into mining or just continue running a full node, that helps the network as well.
I stopped ASIC mining in 2013.

Because it would be dead code and dead weight in the codebase. IIRC the CPU miner got fairly complex because it was using different CPU instructions and extensions and various tricks to make computing SHA256 hashes faster. This means that it was complex. If the CPU miner was still in Core, it would still have to be maintained which adds additional burden on developers. It means that refactors are a bit harder. It means that we would needs tests for it. Because it would be consensus related, it means that people have to review it more carefully, and if there are bugs, those have to be fixed. There would be feature requests related to the miner to do things like make it support Stratum and pool mining. In general, more work is required to maintain it, but it is a feature that few, if any, people would use at all. It was eventually decided that it was not worth maintaining a feature that basically no one used, so the CPU miner was removed.

Even so, there were other mining software that had more efficient CPU miners and more mining features than Core even when it still had a miner built in. So people who wanted to CPU mine weren't using Core anyways.

What if developers decide maintaining blockchain code is too much of burden and move to centralized ledger hosted on MtGox servers or vacant OneCoin database? I know this is joke but You got my point.

I am not a programmer but I have no idea why a subroutine that does not need to be touched is a burden. Just do not modify the code lines responsible for CPU mining, problem solved!

Bitcoin was goatsed in various ways in its lifetime. Worst thing that happened to Bitcoin was moving from original interface to Qt crap still making my eyes bleed today. I never successfully mined block using CPU miner in past, but I turned it on to get the idea how things happen.

you are confusing Bitcoin (the protocol) with bitcoin core (the client). there is a big difference between what the protocol defines and is a part of consensus and what kind of features a client offers.
the CPU mining was just a feature that the client had and got removed, it doesn't change anything. there is a lot of other features that bitcoin core doesn't have. if you don't like it then either use another client (ie. some other implementation of Bitcoin) or you can fork it and add the feature and maintain it yourself (or pay some programmer to do it for your use).

Every 4 year (actually every 210,000 blocks) the reward for mining a block is divided by two in other words the miners get 50% less for verifying transactions on the blockchain.
It will be reduced from 12.5 to 6.25 bitcoins per block.

Previously I managed to make a signature on Console of the Bitcoin Core using the Legacy Address, but when trying with the SegWit Address the following message appears:

https://i.imgur.com/4mTlcfC.png

Please explain and the solution.
Thanks.

There is no solution and you cannot sign a message with a segwit address. This has been the case since segwit was introduced. See https://github.com/bitcoin/bitcoin/issues/10542

I see Bitcoin core was updated to 0.19.1
https://bitcoincore.org/en/2020/03/09/release-0.19.1/

Bitcoin Core 0.19.1 is now available (https://bitcointalk.org/index.php?topic=5231808.0)
