This release includes the following features and fixes:
+ - The node's known peers are persisted to disk in a file called `peers.dat`. The
+ format of this file has been changed in a backwards-incompatible way in order to
+ accommodate the storage of Tor v3 and other BIP155 addresses. This means that if
+ the file is modified by 0.23.0 or newer then older versions will not be able to
+ read it. Those old versions, in the event of a downgrade, will log an error
+ message that deserialization has failed and will continue normal operation
+ as if the file was missing, creating a new empty one.
