+# Changes
+
+## Version 1.2
+
+Previously, if a Host declaration or a value had trailing whitespace, that
+whitespace would have been included as part of the value. This led to unexpected
+consequences. For example:
+
+```
+Host example       # A comment
+    HostName example.com      # Another comment
+```
+
+Prior to version 1.2, the value for Host would have been "example " and the
+value for HostName would have been "example.com      ". Both of these are
+unintuitive.
+
+Instead, we strip the trailing whitespace in the configuration, which leads to
+more intuitive behavior.
