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 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 10.12+, 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. + +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. + +Known Bugs +========== + +The process for generating the source code release ("tarball") has changed in an +effort to make it more complete, however, there are a few regressions in +this release: + +- The generated `configure` script is currently missing, and you will need to + install autotools and run `./autogen.sh` before you can run + `./configure`. This is the same as when checking out from git. + +- Instead of running `make` simply, you should instead run + `BITCOIN_GENBUILD_NO_GIT=1 make`. + +Notable changes +=============== + +Changes regarding misbehaving peers +----------------------------------- + +Peers that misbehave (e.g. send us invalid blocks) are now referred to as +discouraged nodes in log output, as they're not (and weren't) strictly banned: +incoming connections are still allowed from them, but they're preferred for +eviction. + +Furthermore, a few additional changes are introduced to how discouraged +addresses are treated: + +- Discouraging an address does not time out automatically after 24 hours + (or the `-bantime` setting). Depending on traffic from other peers, + discouragement may time out at an indeterminate time. + +- Discouragement is not persisted over restarts. + +- There is no method to list discouraged addresses. They are not returned by + the `listbanned` RPC. That RPC also no longer reports the `ban_reason` + field, as `"manually added"` is the only remaining option. + +- Discouragement cannot be removed with the `setban remove` RPC command. + If you need to remove a discouragement, you can remove all discouragements by + stop-starting your node. + +Notification changes +-------------------- + +`-walletnotify` notifications are now sent for wallet transactions that are +removed from the mempool because they conflict with a new block. These +notifications were sent previously before the v0.19 release, but had been +broken since that release (bug +[#18325](https://github.com/bitcoin/bitcoin/issues/18325)). + +PSBT changes +------------ + +PSBTs will contain both the non-witness utxo and the witness utxo for segwit +inputs in order to restore compatibility with wallet software that are now +requiring the full previous transaction for segwit inputs. The witness utxo +is still provided to maintain compatibility with software which relied on its +existence to determine whether an input was segwit. + +0.20.2 change log +================= + +### P2P protocol and network code + +- #19620 Add txids with non-standard inputs to reject filter (sdaftuar) +- #20146 Send post-verack handshake messages at most once (MarcoFalke) + +### Wallet + +- #19740 Simplify and fix CWallet::SignTransaction (achow101) + +### RPC and other APIs + +- #19836 Properly deserialize txs with witness before signing (MarcoFalke) +- #20731 Add missing description of vout in getrawtransaction help text (benthecarman) + +### Build system + +- #20142 build: set minimum required Boost to 1.48.0 (fanquake) +- #20298 use the new plistlib API (jonasschnelli) +- #20880 gitian: Use custom MacOS code signing tool (achow101) +- #22190 Use latest signapple commit (achow101) + +### Tests and QA + +- #19839 Set appveyor vm version to previous Visual Studio 2019 release.
