+The next generation and release of Chart.js (v2.0) has been well under way this year and we are very close to releasing some amazing new features including, but not limited to:
+- Rewritten, optimized, and unit-tested
+- New and improved scales (log, time, linear, category, multiple scales)
+- Improved Tooltips and tooltip callbacks for customization
+- Improved responsiveness and resizing
+- Powerful support for adding, removing, changing, and updating data on the fly
+- Animations for everything, including all elements, colors and tooltips
+- Powerful customization when you need it. Automatic and dynamic when you don't.
+- Excellent support for modern frameworks and modular build systems.
+- Even more extensible via new element controllers, core scale classes, combo chart support, and hook systems
+- Bug fixes, stability improvements, etc.

+v1.x is now considered feature complete.  PR's for bug fixes are still extremely welcome.  Any open PR's for v1.x features will need to be reconsidered, refactored and resubmitted for v2.x (if the feature has not already been implemented).

+For the `tooltipTemplate` and `multiTooltipTemplate` configuration options, you may use special template blocks. **Do not use user input in the tooltip template, as it may be executed as raw JavaScript.**
+
+Anything in between `<%` and `%>` will be executed as JavaScript. As in the example shown above, `<% if (label) { %>` and later `<% } %>`. Using `<%= expr %>` will print the value of the variable named by `expr` into the tooltip.

+The available variables to print into the tooltip depends on the chart type. In general, the following variables are available:
+
+```javascript
+{
+	value : "value of the data point",
+	label : "label for the position the data point is at",
+	datasetLabel: "label for the dataset the point is from",
