Tools and Utilities
-------------------
- A new CLI `-addrinfo` command returns the number of addresses known to the
node per network type (including Tor v2 versus v3) and total. This can be
useful to see if the node knows enough addresses in a network to use options
like `-onlynet=<network>` or to upgrade to current and future Tor releases
that support Tor v3 addresses only. (#21595)
