 keras (2.0.9-1) UNRELEASED; urgency=medium
 
   * Extend upstream copyright to 2017.
+  * Add autopkgtest
+    + Checks that module loads, optimizes a simple network.
+    + Add allow-stderr restriction because impossible to suppress
+      backend announcement ("Using Theano backend.") on stderr.
   * Add new package keras-doc:
     + Include docs built by mkdocs.
     + Patch to add missing images pulled from Keras website
