@@@ -14,10 -14,10 +14,12 @@@ The document follows the conventions de
  - added `SVG.$()` and `SVG.$$()` which will query for one/multiple elements
  - added `text()` method to `SVG.Path` to create a textPath from this path (#705)
  - added `SVG.HTMLNode` which is the object wrapped around html nodes to put something in them
+ - added `dispatch()` method on `SVG.Element` which returns the dispatched event for event cancelation (#550)
+ - added `isRoot()` on `SVG.Doc` (#809)
  - added `random` option and `randomize()` method to `SVG.Color` -> __TODO!__
  - added `precision()` method to round numeric element attributes -> __TODO!__
 +- added a linter during the npm build process
 +- added `npm build:dev` to let you develop without getting too annoyed
  
  ### Removed
  - removed `SVG.Array.split()` function
@@@ -60,10 -61,8 +63,10 @@@
  - default constructor now has an optional `node` argument which is used to consruct the object e.g. `new SVG.Rect(rectNode)`
  - SVG.Elements constructor now tries to import svgjs:data from the node
  - `SVG.on()` calls the listener in the context of the passed object. el.on always uses the svg.js object as context
- - `SVG.on()` and `el.on()` now accepts multiple comma or space seperated events e.g. "mousedown, foo bar" (#727)
 -- `SVG.on()/off()` and `el.on()/off()` now accepts multiple comma or space seperated events e.g. "mousedown, foo bar" (#727)
++- `SVG.on()/off()` and `el.on()/off()` now accepts multiple comma or space separated events e.g. "mousedown, foo bar" (#727)
 +- Matrices now apply transformations like `scale`, `translate`, etc... by left multiplying them to simplify transformations
 +- Transforming an element is now much simpler
- -
+ - merged `SVG.Doc` and `SVG.Nested`, added `isRoot()` on `SVG.Doc()` (#809)
  
  ### Fixed
  - fixed a bug in clipping and masking where empty nodes persists after removal -> __TODO!__
