If <category>:<level> is supplied, the setting will override the global one and may be specified multiple times to set multiple category-specific levels. <category> can be: addrman, bench, blockstorage, cmpctblock, coindb, estimatefee, http, i2p, ipc, leveldb, libevent, lock, mempool, mempoolrej, net, proxy, prune, qt, rand, reindex, rpc, selectcoins, tor, util, validation, walletdb, zmq. ``` See the individual commit messages for details. ACKs for top commit: jonatack: One final push per `git range-diff a5d5569 ce3c4c9 9580480` (should be trivial to re-ACK) to ensure this pull changes no default behavior in any way for users or the tests/CI in order to be completely v24 compatible, to update the unit test setup in general, and to update the debug logging section in the developer notes. klementtan: reACK9580480570

Bitcoin Core
Setup
Bitcoin Core is the original Bitcoin client and it builds the backbone of the network. It downloads and, by default, stores the entire history of Bitcoin transactions, which requires a few hundred gigabytes of disk space. Depending on the speed of your computer and network connection, the synchronization process can take anywhere from a few hours to a day or more.
To download Bitcoin Core, visit bitcoincore.org.
Running
The following are some helpful notes on how to run Bitcoin Core on your native platform.
Unix
Unpack the files into a directory and run:
bin/bitcoin-qt
(GUI) orbin/bitcoind
(headless)
Windows
Unpack the files into a directory, and then run bitcoin-qt.exe.
macOS
Drag Bitcoin Core to your applications folder, and then run Bitcoin Core.
