@@ -55,6 +55,7 @@ The document follows the conventions described in [“Keep a CHANGELOG”](http:
 - `SVG.Nested` is not `overflow:visible` by default
 - all `SVG.*` objects now can have a node as parameter when constructing
 - `SVG()` does not set a default size anymore
+- default constructor now has an optional `node` argument which is used to consruct the object e.g. `new SVG.Rect(rectNode)`
 
 ### Fixed
 - fixed a bug in clipping and masking where empty nodes persists after removal -> __TODO!__
