* The color designated by 'defaultbg' should not be used elsewhere.
* Embedding might fail after applying this patch.
+Changes in 0.8.2
+----------------
+* The internal method for querying X visual is changed. St will respect the
+ visual of its parent window, allowing it to be embedded easily.
+* Opacity value is now typed in float.
+* `-A` option is added to allow changing the opacity value without compiling.
