 ### New and noteworthy
 
+#### New Rules
+
+##### AccessorMethodGeneration (java-design)
+
+When accessing a private field / method from another class, the Java compiler will generate a accessor methods
+with package-private visibility. This adds overhead, and to the dex method count on Android. This situation can
+be avoided by changing the visibility of the field / method from private to package-private.
+
+For instance, it would report violations on code such as:
+
+```
+public class OuterClass {
+    private int counter;
+    /* package */ int id;
+
+    public class InnerClass {
+        InnerClass() {
+            OuterClass.this.counter++; // wrong, accessor method will be generated
+        }
+
+        public int getOuterClassId() {
+            return OuterClass.this.id; // id is package-private, no accessor method needed
+        }
+    }
+}
+```
+
+This new rule is part of the `java-design` ruleset.
