Adds container option for sticky, adds checkbox vars

RELEASE-NOTES.md

@@ -6,6 +6,8 @@
 - **Search** - Fixed issue where pressing "up" key when no results selected would cause bottom result to be selected
 
 **Enhancements**
+- **Checkbox** - Adds additional variables for styling toggle checkbox on/off state
+-  **Sticky** - Adds `container` setting. This can be used to specify the offsetParent of the sticky element and avoid having to calculate on initialization (improving performance)
 - **Progress** - Progress now includes transitionEnd failback for progress bar animations, this will prevent labels from continuing to be updated if the `transitionEnd` css callback does not fire correctly
 - **Transition** - You can now specify `data-display` to specify the final display state for an animation in cases that it is detected incorrectly (you can also pass in as a setting)
