First of all, **No change is required if you are using default configuration.**
* **instrumentors:**
Version 0.8.0 introduces [escallmatch](https://github.com/twada/escallmatch) syntax for configuration.
If you are:
* using instrumentors such as `espower-loader`, `grunt-espower`, `gulp-espower`, `espowerify` and `espower-coffee`
* or using `espower-source` or `espower` directly
And
* having custom instrumentation pattern using `powerAssertVariableName` or `targetMethods` property
Then you need to migarte. To migrate, please see CHANGELOG for the instrumentor you choose.
