+# Change Log
+
+## [0.1.0] - 2015-02-15
+### Added
+- Remove options that are not present in host definition.
+  E.g. if the `user` option is set in the config file and is not
+  set in ansible then it will be removed on the nextansible run.
+  (@z38 on GitHub)
+- Allow the config file for the root user to be set.
+  Previous versions assumed that the default user was root and that the
+  config file was `/etc/ssh/ssh_config`.
+
+  It has now been changed so that
+  if the user is unset then the config file will be `/etc/ssh/ssh_config`
+  and if `root` is set then the config file in root's home directory will
+  be used.
+  (@z38)
+- New options:
+    - `remote_user` - @z38
+    - `user_known_hosts_file` - @gaqzi
+    - `strict_host_key_checking` - @gaqzi
