Updated RPCs
------------
- `getpeerinfo` no longer returns the following fields: `addnode`, `banscore`,
and `whitelisted`, which were previously deprecated in 0.21. Instead of
`addnode`, the `connection_type` field returns manual. Instead of
`whitelisted`, the `permissions` field indicates if the peer has special
privileges. The `banscore` field has simply been removed. (#20755)
Changes to Wallet or GUI related RPCs can be found in the GUI or Wallet section below.
