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 it 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 10.12+, 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 Bitcoin Core 0.20.0 onwards, macOS versions earlier than 10.12 are no -longer supported. Additionally, Bitcoin Core does not yet change appearance -when macOS "dark mode" is activated. - -In addition to previously supported CPU platforms, this release's pre-compiled -distribution provides binaries for the RISC-V platform. - -Notable changes -=============== - -P2P and network changes ------------------------ - -#### Removal of reject network messages from Bitcoin Core (BIP61) - -The command line option to enable BIP61 (`-enablebip61`) has been removed. - -This feature has been disabled by default since Bitcoin Core version 0.18.0. -Nodes on the network can not generally be trusted to send valid ("reject") -messages, so this should only ever be used when connected to a trusted node. -Please use the recommended alternatives if you rely on this deprecated feature: - -* Testing or debugging of implementations of the Bitcoin P2P network protocol - should be done by inspecting the log messages that are produced by a recent - version of Bitcoin Core. Bitcoin Core logs debug messages - (`-debug=<category>`) to a stream (`-printtoconsole`) or to a file - (`-debuglogfile=<debug.log>`). - -* Testing the validity of a block can be achieved by specific RPCs: - - `submitblock` - - `getblocktemplate` with `'mode'` set to `'proposal'` for blocks with - potentially invalid POW - -* Testing the validity of a transaction can be achieved by specific RPCs: - - `sendrawtransaction` - - `testmempoolaccept` - -* Wallets should not use the absence of "reject" messages to indicate a - transaction has propagated the network, nor should wallets use "reject" - messages to set transaction fees. Wallets should rather use fee estimation - to determine transaction fees and set replace-by-fee if desired. Thus, they - could wait until the transaction has confirmed (taking into account the fee - target they set (compare the RPC `estimatesmartfee`)) or listen for the - transaction announcement by other network peers to check for propagation. - -The removal of BIP61 REJECT message support also has the following minor RPC -and logging implications: - -* `testmempoolaccept` and `sendrawtransaction` no longer return the P2P REJECT - code when a transaction is not accepted to the mempool. They still return the - verbal reject reason. - -* Log messages that previously reported the REJECT code when a transaction was - not accepted to the mempool now no longer report the REJECT code. The reason - for rejection is still reported. - -Updated RPCs ------------- - -- `testmempoolaccept` and `sendrawtransaction` no longer return the P2P REJECT - code when a transaction is not accepted to the mempool. See the Section - _Removal of reject network messages from Bitcoin Core (BIP61)_ for details on - the removal of BIP61 REJECT message support. - -- A new descriptor type `sortedmulti(...)` has been added to support multisig scripts where the public keys are sorted lexicographically in the resulting script. - -- `walletprocesspsbt` and `walletcreatefundedpsbt` now include BIP 32 derivation paths by default for public keys if we know them. This can be disabled by setting `bip32derivs` to `false`. - -Build System ------------- - -- OpenSSL is no longer used by Bitcoin Core. The last usage of the library -was removed in #17265. - -- glibc 2.17 or greater is now required to run the release binaries. This -retains compatibility with RHEL 7, CentOS 7, Debian 8 and Ubuntu 14.04 LTS. -Further details can be found in #17538. - -New RPCs --------- - -New settings ------------- - -- RPC Whitelist system. It can give certain RPC users permissions to only some RPC calls. -It can be set with two command line arguments (`rpcwhitelist` and `rpcwhitelistdefault`). (#12763) - -- A new `-asmap` configuration option has been added to enable IP-to-ASN mapping - for bucketing of the network peers to diversify the network connections. The - legacy /16 prefix mapping remains the default. See [issue - #16599](https://github.com/bitcoin/bitcoin/issues/16599), [PR - #16702](https://github.com/bitcoin/bitcoin/pull/16702), and the `bitcoind - help` for more information. This option is experimental and subject to changes - or removal in future releases. - -Updated settings ----------------- - -Importing blocks upon startup via the `bootstrap.dat` file no longer occurs by default. The file must now be specified with `-loadblock=<file>`. - -- The `-debug=db` logging category has been renamed to `-debug=walletdb`, to distinguish it from `coindb`. - `-debug=db` has been deprecated and will be removed in the next major release. - -GUI changes ------------ - -- The "Start Bitcoin Core on system login" option has been removed on macOS. - -Wallet ------- - -- The wallet now by default uses bech32 addresses when using RPC, and creates native segwit change outputs. -- The way that output trust was computed has been fixed in #16766, which impacts confirmed/unconfirmed balance status and coin selection. - -- The RPC gettransaction, listtransactions and listsinceblock responses now also -includes the height of the block that contains the wallet transaction, if any. - -- RPC `getaddressinfo` changes: - - - the `label` field has been deprecated in favor of the `labels` field and - will be removed in 0.21. It can be re-enabled in the interim by launching - with `-deprecatedrpc=label`. - - - the `labels` behavior of returning an array of JSON objects containing name - and purpose key/value pairs has been deprecated in favor of an array of - label names and will be removed in 0.21. The previous behavior can be - re-enabled in the interim by launching with `-deprecatedrpc=labelspurpose`. - -Low-level changes -================= - -Command line ------------- - -Command line options prefixed with main/test/regtest network names like -`-main.port=8333` `-test.server=1` previously were allowed but ignored. Now -they trigger "Invalid parameter" errors on startup. - -Tests ------ - -- It is now an error to use an unqualified `walletdir=path` setting in the config file if running on testnet or regtest - networks. The setting now needs to be qualified as `chain.walletdir=path` or placed in the appropriate `[chain]` - section. (#17447) - -- `-fallbackfee` was 0 (disabled) by default for the main chain, but 0.0002 by default for the test chains. Now it is 0 - by default for all chains. Testnet and regtest users will have to add `fallbackfee=0.0002` to their configuration if - they weren't setting it and they want it to keep working like before.
