- **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 dashboard 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.
- **Elasticsearch**: Elasticsearch metric queries without date histogram now return table formatted data making table panel much easier to use for this use case. Should not break/change existing dashboards with stock panels but external panel plugins can be affected.
## Changes
- **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 parenthesis around tag filters in queries [#9131](https://github.com/grafana/grafana/pull/9131)

- **Templating**: You cannot select data source variables as data source for other template variables [#7510](https://github.com/grafana/grafana/issues/7510)
- **MySQL/Postgres**: Fix for max_idle_conn option default which was wrongly set to zero which does not mean unlimited but means zero, which in practice kind of disables connection pooling, which is not good. Fixes [#8513](https://github.com/grafana/grafana/issues/8513)
# 4.4.3 (2017-08-07)
## Bug Fixes
- **Search**: Fix for issue that caused search view to hide when you clicked starred or tags filters, fixes [#8981](https://github.com/grafana/grafana/issues/8981)
