+Bug Fixes
+"""""""""
+
+* Fix the ``-o/--output`` option (bytes->str conversion) (`T200622`_):
+
+  * The migration to Python3 left the ``-o/--output`` option of the CLI with some decoding issue from bytes to string.
+  * Uniforming all calls to ``bytes.decode()`` not specifying the encoding as ``utf-8`` is the default in Python 3.
+  * Add integration tests for the ``-o/--output`` option.
+
+* CLI: fix ``setup_logging()`` when called without path (`T188627`_):
+
+  * Fix the ``setup_logging()`` function when it's called with a filename without a path, in order to log directly
+    into the current directory. Thanks goes to aggro for reporting it.
+
+* Fix debugging log message conversion. The Command.timeout can also be None in case is not set, converting it to
+  string instead of integer for the debug messages.
