+    - Remove ``QPDFObject.hh`` from the public ``include/qpdf``
+      directory. The only use case for including
+      ``qpdf/QPDFObject.hh`` was to get ``QPDFObject::object_type_e``.
+      Since 10.5.0, this has been an alias to ``qpdf_object_type_e``,
+      defined in ``qpdf/Constants.h``. To fix your code, replace any
+      includes of ``qpdf/QPDFObject.hh`` with ``qpdf/Constants.h``,
+      and replace all occurrences of ``QPDFObject::ot_`` with
+      ``::ot_``. If you need your code to be backward compatible to
+      qpdf versions prior to 10.5.0, you can check that the
+      preprocessor symbol ``QPDF_MAJOR_VERSION`` is defined and ``>=
+      11``.

     - Pipeline::write now takes ``unsigned char const*`` instead of
       ``unsigned char*``. Callers don't need to change anything, but
       you no longer have to pass writable pointers to pipelines. If
