 v1.8.1 (DD MM YYYY)
 -------------------
 
+* #90: Ensure that callbacks handed to `SFTPClient.get()` always fire at least
+  once, even for zero-length files downloaded. Thanks to Github user `@enB` for
+  the catch.
+* #85: Paramiko's test suite overrides
+  `unittest.TestCase.assertTrue/assertFalse` to provide these modern assertions
+  to Python 2.2/2.3, which lacked them. However on newer Pythons such as 2.7,
+  this now causes deprecation warnings. The overrides have been patched to only
+  execute when necessary. Thanks to `@Arfrever` for catch & patch.
