 - Calls to `getblocktemplate` will fail if the segwit rule is not specified.
   Calling `getblocktemplate` without segwit specified is almost certainly
   a misconfiguration since doing so results in lower rewards for the miner.

-Command line option changes
----------------------------
-
-The `-enablebip61` command line option (introduced in Bitcoin Core 0.17.0) is
-used to toggle sending of BIP 61 reject messages. Reject messages have no use
-case on the P2P network and are only logged for debugging by most network
-nodes. The option will now by default be off for improved privacy and security
-as well as reduced upload usage. The option can explicitly be turned on for
-local-network debugging purposes.
+  Failed calls will produce an error message describing how to enable the
+  segwit rule.
+
+Configuration option changes
+----------------------------
+
+- A warning is printed if an unrecognized section name is used in the
+  configuration file.  Recognized sections are `[test]`, `[main]`, and
+  `[regtest]`.

+
+- The `rpcallowip` option can no longer be used to automatically listen
+  on all network interfaces.  Instead, the `rpcbind` parameter must also
+  be used to specify the IP addresses to listen on.  Listening for RPC
+  commands over a public network connection is insecure and should be
+  disabled, so a warning is now printed if a user selects such a
+  configuration.  If you need to expose RPC in order to use a tool
+  like Docker, ensure you only bind RPC to your localhost, e.g. `docker
+  run [...] -p 127.0.0.1:8332:8332` (this is an extra `:8332` over the
+  normal Docker port specification).
+
+- The `rpcpassword` option now causes a startup error if the password
+  set in the configuration file contains a hash character (#), as it's
+  ambiguous whether the hash character is meant for the password or as a
+  comment.
