Please feel free to link to the files at github.highcharts.com. This is offered as a convenience when programming and should not be used in production.
The file path can be pointed to a specific branch, commit or tag in our GitHub repo. Both Highcharts and Highstock share the same repo, so you'll find highcharts.src.js and highstock.src.js on the same level.
