 # 1.0.0-rc.10 (?/?/2014)
 
-- remove internal references everywhere -> __TODO!__
+- remove structural references everywhere
 - rework transformation to be chainable and more true to native SVG -> __TODO!__
-- implement an SVG adoption system to be able to manipulate existing SVG's not created with svg.js -> __TODO!__
+- implement an SVG adoption system to be able to manipulate existing SVG's not created with svg.js
 - fixed a bug in clipping and masking where empty nodes persists after removal -> __TODO!__
 - added support to clone manually built text elements -> __TODO!__
 - using `CustomEvent` instead of `Event` to be able to fire events with a `detail` object [thanks @Fuzzyma]

-### By class name
+### By CSS selector
+There are two ways to select elements using CSS selectors.
+
+The first is to search globally. This will search in all svg elements in a document and return them in an instance of `SVG.Set`:
+
+```javascript
+var elements = SVG.select('rect.my-class')
+
+elements.fill('#f06')
+```
+
+The second is to search within a parent element:
+
+```javascript
+var elements = group.select('rect.my-class')
+
+elements.x(100)
+```
+
+
+### Using jQuery
 There is no DOM querying system built into svg.js but [jQuery](http://jquery.com/) or [Zepto](http://zeptojs.com/) will help you achieve this. Here is an example:
