+Non variables detected as variable by variable rules (#982)
+-----------------------------------------------------------
+
+String literals will no longer be detected as variables by variables rules such as W0919 ``unused-argument``
+or I0920 ``unused-variable``::
+
+    Used In String Literal
+        [Arguments]    ${used}    ${unused}
+        Log  ${used} unused  # unused is just a string, not a variable
+
+Global variables used in the loop before assigning variable (#868)
+------------------------------------------------------------------
+
+The variable rules (such as W0919 ``unused-argument`` or I0920 ``unused-variable``) were not aware of the recursive
+nature of the loops. For example if variable was used before it was declared in the loop (original value could
+originate from global variable), it was marked as unused. Following code should not report unused variables anymore::
+
+    Loop With Global Count
+        FOR    ${item}    IN    @{LIST}
+            Set To Dictionary    ${item}    displayOrder=${count}
+            ${count}    Evaluate    ${count} + 1
+        END
