Updated RPCs
------------
Deprecated or removed RPCs
--------------------------
- The `signrawtransaction` RPC is removed after being deprecated and
hidden behind a special configuration option in version 0.17.0.
- The 'account' API is removed after being deprecated in v0.17. The
'label' API was introduced in v0.17 as a replacement for accounts.
See the [release notes from v0.17](https://github.com/bitcoin/bitcoin/blob/master/doc/release-notes/release-notes-0.17.0.md#label-and-account-apis-for-wallet)
for a full description of the changes from the 'account' API to the
'label' API.
- The `addwitnessaddress` RPC is removed after being deprecated in
version 0.13.0.
- The wallet's `generate` RPC method is deprecated and will be fully
removed in a subsequent major version. This RPC is only used for
testing, but its implementation reached across multiple subsystems
(wallet and mining), so it is being deprecated to simplify the
wallet-node interface. Projects that are using `generate` for testing
purposes should transition to using the `generatetoaddress` RPC, which
does not require or use the wallet component. Calling
`generatetoaddress` with an address returned by the `getnewaddress`
RPC gives the same functionality as the old `generate` RPC. To
continue using `generate` in this version, restart bitcoind with the
`-deprecatedrpc=generate` configuration option.
New RPCs
--------
- A new `getnodeaddresses` RPC returns peer addresses known to this
node. It may be used to find nodes to connect to without using a DNS
seeder.
- A new `listwalletdir` RPC returns a list of wallets in the wallet
directory (either the default wallet directory or the directory
configured by the `-walletdir` parameter).
Updated RPCs

Note: some low-level RPC changes mainly useful for testing are described
in the Low-level Changes section below.
- The `getpeerinfo` RPC now returns an additional "minfeefilter" field
set to the peer's BIP133 fee filter. You can use this to detect that
you have peers that are willing to accept transactions below the

- The `getaddressinfo` RPC now provides an `ischange` field indicating
whether the wallet used the address in a change output.
- The `importmulti` RPC has been updated to support P2WSH, P2WPKH,
P2SH-P2WPKH, and P2SH-P2WSH. Requests for P2WSH and P2SH-P2WSH accept
an additional `witnessscript` parameter.

- A new `submitheader` RPC allows submitting block headers independently

Configuration
-------------
- The `-usehd` configuration option was removed in version 0.16. From
that version onwards, all new wallets created are hierarchical
deterministic wallets. This release makes specifying `-usehd` an
