Here's a rundown of the changes:

• Regressions: We now have regression tools for timeline and scatter! Supported types are: Linear, Quadratic, Cubic, Logarithmic, and Exponential. These are available in a new toolbox within those visualization types. Keep in mind they are still a bit experimental, so please let us know if you find any problems.

• Tweaks to Heatmap Weighting: Now if you select a field other than 'Marker Density' in the heatmap, its weight is skewed much more heavily towards the values present in an area, rather than the density of points. The result in general has been more meaningful heatmaps in our experience.

• Templates: We have put in a new template system for writing content blocks. Right now there is just one for a basic project, but in the future we will be expanding these with more templates for projects, and other content blocks (like saved visualization, data sets, etc...).

• Under the Hood: We have been continuing to fix the various bugs that have popped up after the switch to 3.0. A notable switch here is the edit button for content blocks is back, allowing users to click their own links again (sorry about that!).
