+
+### New and noteworthy
+
+#### Lua now supports additionally Luau
+
+This release of PMD adds support for [Luau](https://github.com/Roblox/luau), a gradually typed language derived
+from Lua. This means, that the Lua language in PMD can now parse both Lua and Luau.
+
+#### Modified rules
+
+* The Java rule [`UnusedPrivateField`](https://pmd.github.io/pmd-6.50.0/pmd_rules_java_bestpractices.html#unusedprivatefield) now ignores private fields, if the fields are
+  annotated with any annotation or the enclosing class has any annotation. Annotations often enable a
+  framework (such as dependency injection, mocking or e.g. Lombok) which use the fields by reflection or other
+  means. This usage can't be detected by static code analysis. Previously these frameworks where explicitly allowed
+  by listing their annotations in the property "ignoredAnnotations", but that turned out to be prone of false
+  positive for any not explicitly considered framework. That's why the property "ignoredAnnotations" has been
+  deprecated for this rule.
+* The Java rule [`CommentDefaultAccessModifier`](https://pmd.github.io/pmd-6.50.0/pmd_rules_java_codestyle.html#commentdefaultaccessmodifier) now by default ignores JUnit5 annotated
+  methods. This behavior can be customized using the property `ignoredAnnotations`.
