- 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.

Graphical User Interface (GUI)
------------------------------
- A new Window menu is added alongside the existing File, Settings, and
Help menus. Several items from the other menus that opened new
windows have been moved to this new Window menu.
- In the Send tab, the checkbox for "pay only the required fee"
has been removed. Instead, the user can simply decrease the value in
the Custom Feerate field all the way down to the node's configured
minimum relay fee.

and the `disable_private_keys` parameter was set to true.

Changes for particular platforms
--------------------------------
- On macOS, Bitcoin Core now opts out of application CPU throttling
("app nap") during initial blockchain download, when catching up from
over 100 blocks behind the current chain tip, or when reindexing chain
data. This helps prevent these operations from taking an excessively
long time because the operating system is attempting to conserve
power.
