 ### 🚀 New and noteworthy
 
+#### CPD can now ignore literals and identifiers in C++ code
+
+When searching for duplicated code in C++ differences in literals or identifiers can be
+ignored now (like in Java). This can be enabled via the command line options `--ignore-literal`
+and `--ignore-identifiers`.  
+See [PR #5040](https://github.com/pmd/pmd/pull/5040) for details.
