Notable changes

P2P and network changes

Previously if Bitcoin Core was listening for P2P connections, either using default settings or via bind=addr:port it would always also bind to 127.0.0.1:8334 to listen for Tor connections. It was not possible to switch this off, even if the node didn't use Tor. This has been changed and now bind=addr:port results in binding on addr:port only. The default behavior of binding to 0.0.0.0:8333 and 127.0.0.1:8334 has not been changed.

If you are using a bind=... configuration without bind=...=onion and rely on the previous implied behavior to accept incoming Tor connections at 127.0.0.1:8334, you need to now make this explicit by using bind=... bind=127.0.0.1:8334=onion. (#22729)
Bitcoin Core will now fail to start up if any of its P2P binds fail, rather than the previous behaviour where it would only abort startup if all P2P binds had failed. (#22729)
