 byobu (5.53) unreleased; urgency=low
 
-  * UNRELEASED
+  * usr/bin/byobu-launch, usr/lib/byobu/ec2_cost,

+    usr/lib/byobu/ip_address: LP: #1208853
+    - revert this recent commit, as it appears to have some unintended
+      consequences, and it was just cleaning up some false positive
+      bashism hits
