 Changes in existing checks
 ^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+- Fixed false-positive in :doc:`bugprone-branch-clone
+  <clang-tidy/checks/bugprone/branch-clone>` check by ignoring auto-generated
+  code, template instances, and implicit code patterns.
+
 - Improved :doc:`readability-redundant-string-cstr
   <clang-tidy/checks/readability/redundant-string-cstr>` check to recognise
   unnecessary ``std::string::c_str()`` and ``std::string::data()`` calls in
