 ## Apply a fix
 When an issue is resolved, we commit a fix and mark the issue closed. This doesn't mean that a new release is available with the fix applied, but that it is fixed in the development code and will be added to the next stable release. Stable versions are typically released every 1-3 months. To try out the fix immediately, you can run http://github.highcharts.com/highcharts.js or http://github.highcharts.com/highstock.js from any website, but do not use these URLs in production.
