 UNRELEASED
 ----------
+* ``ConfigUtilities`` now read system properties for a node. This allow to specify data source properties at runtime.
+
 * ``OpaqueBytes.bytes`` now returns a clone of its underlying ``ByteArray``, and has been redeclared as ``final``.
   This is a minor change to the public API, but is required to ensure that classes like ``SecureHash`` are immutable.
