4.5.0 (unreleased)

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 dashboad 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.

Changes

• InfluxDB: Change time range filter for absolute time ranges to be inclusive instead of exclusive #8319, thx @Oxydros
• InfluxDB: Added paranthesis 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

Breaking changes

Data Source Query Editors: Issue #3900

Query editors have been updated to use the new form styles. External data source plugins needs to be updated to work. Sorry to introduce breaking change this late in beta phase. We wanted to get this change in before 3.0 stable is released so we don't have to break data sources in next release (3.1). If you are a data source plugin author and want help for how the new form styles work please ask for help in slack channel (link to slack channel in readme).

Tech (Note for devs) Started using Typescript (transpiled to ES5), uncompiled typescript files and less files are in public folder (in source tree) This folder is never modified by build steps. Compiled css and javascript files are put in public_gen, all other files that do not undergo transformation are just copied from public to public_gen, it is public_gen that is used by grafana-server if it is found.

Grunt & Watch tasks:

• grunt : default task, will remove public_gen, copy over all files from public, do less & typescript compilation
• grunt watch: will watch for changes to less, and typescript files and compile them to public_gen, and for other files it will just copy them to public_gen

UI polish / changes

• Issue #725. UI: All modal editors are removed and replaced by an edit pane under menu. The look of editors is also updated and polished. Search dropdown is also shown as pane under menu and has seen some UI polish.

Filtering/Templating feature overhaul

• Filtering renamed to Templating, and filter items to variables
• Filter editing has gotten its own edit pane with much improved UI and options
• Issue #296. Templating: Can now retrieve variable values from a non-default data source
• Issue #219. Templating: Template variable value selection is now a typeahead autocomplete dropdown
• Issue #760. Templating: Extend template variable syntax to include $variable syntax replacement
• Issue #234. Templating: Interval variable type for time intervals summarize/group by parameter, included "auto" option, and auto step counts option.

• Issue #312. Templating: Can now use template variables in panel titles
• Issue #613. Templating: Full support for InfluxDB, filter by part of series names, extract series substrings, nested queries, multipe where clauses!
• Template variables can be initialized from url, with var-my_varname=value, breaking change, before it was just my_varname.
• Templating and url state sync has some issues that are not solved for this release, see Issue #772 for more details.

InfluxDB Breaking changes

• To better support templating, fill(0) and group by time low limit some changes has been made to the editor and query model schema
• Currently some of these changes are breaking
• If you used custom condition filter you need to open the graph in edit mode, the editor will update the schema, and the queries should work again
• If you used a raw query you need to remove the time filter and replace it with $timeFilter (this is done automatically when you switch from query editor to raw query, but old raw queries needs to updated)
• If you used group by and later removed the group by the graph could break, open in editor and should correct it
• InfluxDB annotation queries that used timeFilter should be updated to use $timeFilter syntax instead
• Might write an upgrade tool to update dashboards automatically, but right now master (1.8) includes the above breaking changes

InfluxDB query editor enhancements

• Issue #756. InfluxDB: Add option for fill(0) and fill(null), integrated help in editor for why this option is important when stacking series
• Issue #743. InfluxDB: A group by time option for all queries in graph panel that supports a low limit for auto group by time, very important for stacking and fill(0)
• The above to enhancements solves the problems associated with stacked bars and lines when points are missing, these issues are solved:
• Issue #673. InfluxDB: stacked bars missing intermediate data points, unless lines also enabled
• Issue #674. InfluxDB: stacked chart ignoring series without latest values
• Issue #534. InfluxDB: No order in stacked bars mode
