+Documentation
+-------------
+
+- A new short
+ [document](https://github.com/bitcoin/bitcoin/blob/master/doc/JSON-RPC-interface.md)
+ about the JSON-RPC interface describes cases where the results of an
+ RPC might contain inconsistencies between data sourced from different
+ subsystems, such as wallet state and mempool state. A note is added
+ to the [REST interface documentation](https://github.com/bitcoin/bitcoin/blob/master/doc/REST-interface.md)
+ indicating that the same rules apply.
+
+- A new [document](https://github.com/bitcoin/bitcoin/blob/master/doc/bitcoin-conf.md)
+ about the `bitcoin.conf` file describes how to use it to configure
+ Bitcoin Core.
+
+- A new document introduces Bitcoin Core's BIP174
+ [Partially-Signed Bitcoin Transactions (PSBT)](https://github.com/bitcoin/bitcoin/blob/master/doc/psbt.md)
+ interface, which is used to allow multiple programs to collaboratively
+ work to create, sign, and broadcast new transactions. This is useful
+ for offline (cold storage) wallets, multisig wallets, coinjoin
+ implementations, and many other cases where two or more programs need
+ to interact to generate a complete transaction.
+
+- The [output script descriptor](https://github.com/bitcoin/bitcoin/blob/master/doc/descriptors.md)
+ documentation has been updated with information about new features in
+ this still-developing language for describing the output scripts that
+ a wallet or other program wants to receive notifications for, such as
+ which addresses it wants to know received payments. The language is
+ currently used in the `scantxoutset` RPC and is expected to be adapted
+ to other RPCs and to the underlying wallet structure.
+
+Build system changes
+--------------------
+
+- A new `--disable-bip70` option may be passed to `./configure` to
+ prevent Bitcoin-Qt from being built with support for the BIP70 payment
+ protocol or from linking libssl. As the payment protocol has exposed
+ Bitcoin Core to libssl vulnerabilities in the past, builders who don't
+ need BIP70 support are encouraged to use this option to reduce their
+ exposure to future vulnerabilities.
+
+Updated RPCs
------------
+- The `signrawtransaction` RPC is removed after being deprecated and
+ hidden behind a special configuration option in version 0.17.0.
+
+- 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
+ default minimum relay fee.
+
+- The mempool RPCs, such as `getrawmempool` with `verbose=true`, now
+ return an additional "bip125-replaceable" value indicating whether the
+ transaction (or its unconfirmed ancestors) opts-in to asking nodes and
+ miners to replace it with a higher-feerate transaction spending any of
+ the same inputs.
+
+- The `settxfee` RPC previously silently ignored attempts to set the fee
+ below the allowed minimums. It now prints a warning. The special
+ value of "0" may still be used to request the minimum value.
+
+- The `getaddressinfo` RPC now provides an `ischange` field indicating
+ whether the wallet used the address in a change output.
+
+Low-level changes
+=================
+
+RPC
+---
+
+- The `submitblock` RPC previously returned the reason a rejected block
+ was invalid the first time it processed that block but returned a
+ generic "duplicate" rejection message on subsequent occasions it
+ processed the same block. It now always returns the fundamental
+ reason for rejecting an invalid block and only returns "duplicate" for
+ valid blocks it has already accepted.
+
+- A new `submitheader` RPC allows submitting block headers independently
+ from their block. This is likely only useful for testing.
