 Version 5.0 Breaking Changes
 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 
+- This driver version introduces the following changes to the ``ConnectionId`` class:
+
+  - The ``ConnectionId`` constructor now accepts a value of type ``long`` as its second
+    parameter instead of type ``int``. Similarly, the constructor now accepts a value of
+    type ``Long`` as its third parameter instead of type ``Integer``. Because this change breaks
+    binary compatibility, recompile any existing code that calls the ``ConnectionId`` constructor.
+
+  - The ``withServerValue()`` method now accepts a parameter of type ``long`` rather than
+    type ``int``. This change breaks binary compatibility, so you must recompile any code
+    that calls the ``withServerValue()`` method.
+
+  - The ``getServerValue()`` method now returns a value of type ``Long`` instead of type
+    ``Integer``. Similarly, the ``getLocalValue()`` method returns a value of type
+    ``long`` instead of type ``int``. Because this change breaks both binary and source
+    compatibility, update any source code that uses these methods and rebuild your binary.
+
 - The driver removes the following record annotations:
 
   - ``BsonId``
