 ## Changelog
 
+#### V1.7 (unreleased)
+- Fixed a lapsuus in AssertThatFileExpression also transforming ```.listFiles()``` with a filter argument.
+
 #### V1.6 (30-Sep-19)
 - Really fixed AssertThatGuavaOptional inspections to avoid conversions from ```.get()``` to ```.contains()```
   for array types. Sigh. Shouldn't be working >12h a day and then do some more stuff at home.

-          for array types. Sigh. Shouldn't be working &gt;12h a day and then do some more stuff at home.
-      <li>Fixed a bug in AssertThatBinaryExpression inspection for assertThat(null != expression) and related
-          that would not correctly invert the condition on transformation.
-      <li>Added new AssertThatFileExpression to move out many common methods from inside the
-          assertThat() expression (exists(), getName(), getParent() and many more).
-      <li>Added several transformations to AssertThatStringExpression inspection.
-          Specifically, uses of matches(), compareToIgnoreCase(), indexOf(), and trim().
+      <li>Fixed a lapsuus in AssertThatFileExpression also transforming listFiles() with a filter argument.
