## Changelog

2.5.1
datasource annotationQuery changed. now single options parameter with:
- range
- rangeRaw
- annotation

2.5 changed the `range` parameter in the `datasource.query` function's options parameter. This
parameter now holds a parsed range with `moment` dates `form` and `to`. To get
millisecond epoch from a `moment` you the function `valueOf`. The raw date range as represented
internally in grafana (which may be relative expressions like `now-5h`) is included in the
new property `rangeRaw` (on the options object).
