4.5.0-beta1 (2017-09-05)

New Features

• Table panel: Render cell values as links that can have an url template that uses variables from current table row. #3754
• Elasticsearch: Add ad hoc filters directly by clicking values in table panel #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

Enhancements

• GitHub OAuth: Support for GitHub organizations with 100+ teams. #8846, thx @skwashd

• Graphite: Calls to Graphite api /metrics/find now include panel or dashboard time range (from & until) in most cases, #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

• Elasticsearch: Ad-hoc filters now use query phrase match filters instead of term filters, works on non keyword/raw fields #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, thx @Oxydros
• InfluxDB: Added parenthesis around tag filters in queries #9131

Bug Fixes

• Modals: Maintain scroll position after opening/leaving modal #8800
• Templating: You cannot select data source variables as data source for other template variables #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

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
• Modals: ESC key now closes modal again, fixes #8981, thx @j-white
