A new (experimental) Mining interface was introduced to support Stratum v2 or other mining client software, see #31098. When the node is started with bitcoin node -m -ipcbind=unix the node will listen on a unix socket for IPC client connections. The -m option launches a new binary bitcoin-node instead of bitcoind.

IPC connectivity introduces new dependencies (see multiprocess.md), which are only included in the bitcoin-node and bitcoin-gui binaries (not in bitcoind and bitcoin-qt). Those new binaries are now built by default (controlled by ENABLE_IPC). If you don't intend to use IPC, nothing changes and there is no need to use bitcoin -m, bitcoin-node or bitcoin-gui(#31802)
