Review last 6 months of JS changelogs

[nicolaskruchten]

Can you please review the last 6 months (or so) of plotly.js changelogs here https://github.com/plotly/plotly.js/releases and compare the new features & changes to our current Python and JS and R docs? Any new features that came out in the last 6 months but aren't clearly documented should be noted here in a comment, and if you can easily fix it by extending an existing example, please feel free to do so :)
