The new query editor has full syntax highlighting. As well as auto complete for metrics, functions, and range vectors.

There is also integrated function docs right from the query editor!

### Elasticsearch: Add ad-hoc filters from the table panel

### Table cell links!
Create column styles that turn cells into links that use the value in the cell (or other other row values) to generate a url to another dashboard or system:
Query Inspector is a new feature that shows query requests and responses. This can be helpful if a graph is not shown or shows something very different than what you expected.

* **Table panel**: Render cell values as links that can have an url template that uses variables from current table row. [#3754](https://github.com/grafana/grafana/issues/3754)
* **Elasticsearch**: Add ad hoc filters directly by clicking values in table panel [#8052](https://github.com/grafana/grafana/issues/8052).
* **MySQL**: New rich query editor with syntax highlighting
* **Prometheus**: New rich query editor with syntax highlighting, metric & range auto complete and integrated function docs. [#5117](https://github.com/grafana/grafana/issues/5117)
### Enhancements
* **GitHub OAuth**: Support for GitHub organizations with 100+ teams. [#8846](https://github.com/grafana/grafana/issues/8846), thx [@skwashd](https://github.com/skwashd)
* **Graphite**: Calls to Graphite api /metrics/find now include panel or dashboad time range (from & until) in most cases, [#8055](https://github.com/grafana/grafana/issues/8055)
* **Graphite**: Added new graphite 1.0 functions, available if you set version to 1.0.x in data source settings. New Functions: mapSeries, reduceSeries, isNonNull, groupByNodes, offsetToZero, grep, weightedAverage, removeEmptySeries, aggregateLine, averageOutsidePercentile, delay, exponentialMovingAverage, fallbackSeries, integralByInterval, interpolate, invert, linearRegression, movingMin, movingMax, movingSum, multiplySeriesWithWildcards, pow, powSeries, removeBetweenPercentile, squareRoot, timeSlice, closes [#8261](https://github.com/grafana/grafana/issues/8261)
- **Elasticsearch**: Ad-hoc filters now use query phrase match filters instead of term filters, works on non keyword/raw fields [#9095](https://github.com/grafana/grafana/issues/9095).
### Breaking change
* **InfluxDB/Elasticsearch**: The panel & data source option named "Group by time interval" is now named "Min time interval" and does now always define a lower limit for the auto group by time. Without having to use `>` prefix (that prefix still works). This should in theory have close to zero actual impact on existing dashboards. It does mean that if you used this setting to define a hard group by time interval of, say "1d", if you zoomed to a time range wide enough the time range could increase above the "1d" range as the setting is now always considered a lower limit.
This option is now rennamed (and moved to Options sub section above your queries):
* **InfluxDB**: Change time range filter for absolute time ranges to be inclusive instead of exclusive [#8319](https://github.com/grafana/grafana/issues/8319), thx [@Oxydros](https://github.com/Oxydros)
* **InfluxDB**: Added paranthesis around tag filters in queries [#9131](https://github.com/grafana/grafana/pull/9131)
## Bug Fixes
* **Modals**: Maintain scroll position after opening/leaving modal [#8800](https://github.com/grafana/grafana/issues/8800)
* **Templating**: You cannot select data source variables as data source for other template variables [#7510](https://github.com/grafana/grafana/issues/7510)
