Bitcoin Core version 25.0 is now available from: release includes new features, various bug fixes and performanceimprovements, as well as updated translations.Please report bugs using the issue tracker at GitHub: receive security and update notifications, please subscribe to: to UpgradeIf you are running an older version, shut it down. Wait until it has completelyshut down (which might take a few minutes in some cases), then run theinstaller (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 ispossible, but it might take some time if the data directory needs to be migrated. Oldwallet versions of Bitcoin Core are generally supported.CompatibilityBitcoin Core is supported and extensively tested on operating systemsusing the Linux kernel, macOS 10.15+, and Windows 7 and newer. BitcoinCore should also work on most other Unix-like systems but is not asfrequently tested on them. It is not recommended to use Bitcoin Core onunsupported systems.Notable changesP2P and network changesTransactions of non-witness size 65 bytes and above are now allowed by mempooland relay policy. This is to better reflect the actual afforded protectionsagainst CVE-2017-12842 and open up additional use-cases of smaller transaction sizes. (#26265)New RPCsThe scanblocks RPC returns the relevant blockhashes from a set of descriptors byscanning all blockfilters in the given range. It can be used in combination withthe getblockheader and rescanblockchain RPCs to achieve fast wallet rescans. Notethat this functionality can only be used if a compact block filter index(-blockfilterindex=1) has been constructed by the node. (#23549)Updated RPCsAll JSON-RPC methods accept a new namedparameter called args that cancontain positional parameter values. This is a convenience to allow someparameter values to be passed by name without having to name every value. Thepython test framework and bitcoin-cli tool both take advantage of this, sofor example:bitcoin-cli -named createwallet wallet_name=mywallet load_on_startup=1Can now be shortened to:bitcoin-cli -named createwallet mywallet load_on_startup=1The 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 dueto missing data while pruning, due to an insufficient dbcache or due tothe 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 willnot be submitted. At present, the outputs deemed unspendable are those with scripts that beginwith an OP_RETURN code (known as 'datacarriers'), scripts

Point that we're recording this, the new Bitcoin Core release has not actually been released yet.Bitcoin Core 22 has not actually been released yet.But by the time this episode is released, then maybe Bitcoin Core 22 is released as well.And otherwise, it will be released very soon, right?Sjors: 00:02:41That's right.There's now a third release candidate out.Aaron: 00:02:44So that means basically any day now, at the point of recording at least.And maybe, like I said, maybe it's out by the time this episode is released.So anyways, we're going to highlight some of the improvements compared to Bitcoin core 21 essentially and bitcoin core 21.1. Was there a bitcoin core 21.2 as well?I don't think so.Sjors: 00:03:09I think there's one in progress.Aaron: 00:03:11Right exactly yeah there's one coming as well.So we're gonna give a short overview of the most notable changes, right?Sjors: 00:03:22Yeah, exactly.So usually the last version digit, those changes are very small.They're usually bug fixes and those kind of things.So the release we're talking about now is a big one.Aaron: 00:03:32They're either very small or they're a protocol upgrade.Sjors: 00:03:36Right.So in this case, it's a bit more complicated because it's small fixes and taproot that go into 0.21.1 and also probably in 0.21.2.Hardware Wallet Support in the GUIAaron: 00:03:47So let's get to Bitcoin Core 22.That's what the episode is about.I think the main, the most notable change, the biggest change, and I think you'll agree with that because you worked on it, so you're biased, is hardware wallet support, the HWI, right?Sjors: 00:04:06I think that's a pretty cool change.I don't know if it's the biggest change.I'm definitely very happy with it.Yeah, so basically if you download Bitcoin Core 22 and then also download HWI, which we talked about in episode 30, which is just a Python script that connects to all sorts of different hardware wallets essentially using their drivers.Then I think you just have to change one setting which is to tell it where you put the HWI script and then once you've done that you just insert your hardware wallet you say to Bitcoin core give me a

New wallet and it'll say "oh do you want to use a trezor, ledger whatever you've just inserted" and it'll just work to him like any other wallet except that your wallet your hardware device will now show on screen "hey do you want to prove this transaction" so that's pretty cool I think.Aaron: 00:05:01Right, but am I understanding you correctly that it does not work out of the box?You can't only download Bitcoin Core 22, you also need to download the HWI.Sjors: 00:05:11Correct.Aaron: 00:05:12Which is a separate software package.Sjors: 00:05:14Yeah, It's a Python library and you know because it contains all the stuff from the hardware manufacturers and it communicates with USB so it is potentially a can of worms and so we don't want to put it in Bitcoin Core for everybody.Maybe one day will be but I think it'll be a while because just including USB drivers into Bitcoin Core sounds a bit scary.Aaron: 00:05:35Right.So for now it's like an add-on.Sjors: 00:05:38Yes.But like I said, pretty easy to install.You download it, put it somewhere, point to it, and that's it.Aaron: 00:05:44Hardware wallets were already supported by Bitcoin Core though, right?Sjors: 00:05:48Indirectly, yes.You could use HWI already, but you had to use it from the command line yourself.And actually HWI also came with a graphical tool, so you could actually use it somewhat you know reasonably, but I think this is much easier now.It's just right into the Bitcoin Core interface.Bitcoin Core InterfaceAaron: 00:06:08Yeah, no one uses the command line, sure.So only a couple of Bitcoin Core developers themselves use that stuff.Regular people.Sjors: 00:06:16A surprising number of Bitcoin Core developers use the graphical interface too and it's especially because coin selection is just a lot easier to do if you want to decide which coins you want to spend using a graphical interface you just click on them whereas with a command line it's horrible, you have to copy paste the transaction hash and the identifier, etc.Which Hardware Wallets are SupportedAaron: 00:06:37Right.So, which hardware wallets are supported?Sjors: 00:06:41Off the top of my head, whatever HWI supports.So, that is
