Grafana v5.1 brings an improved official docker image which should make it easier to run and use the Grafana docker image and at the same time give more control to the user how to use/run it.
We've switched the id of the grafana user running Grafana inside a docker container. Unfortunately this means that files created prior to 5.1 won't have the correct permissions for later versions and thereby this introduces a breaking change.
We made this change so that it would be easier for you to control what user Grafana is executed as (see examples below).
Version | User | User ID
--------|---------|---------
<5.1|grafana|104
>= 5.1 | grafana | 472
Please read the [updated documentation](/installation/docker/#migration-from-a-previous-version-of-the-docker-container-to-5-1-or-later) which includes migration instructions and more information.
Grafana v5.1 brings an improved workflow for provisioned dashboards:
* A populated `id` property in JSON is now automatically removed when provisioning dashboards.
* When making changes to a provisioned dashboard you can `Save` the dashboard which now will bring up a *Cannot save provisioned dashboard* dialog like seen in the screenshot to the right.
Available options in the dialog will let you `Copy JSON to Clipboard` and/or `Save JSON to file` which can help you synchronize your dashboard changes back to the provisioning source.
More information in the [Provisioning documentation](/features/datasources/prometheus/).
We now support a new option for rendering template variables that gives the user full control of how the value(s) should be rendered. In the table below you can see two examples and you can find all different options in the [template variable docs](http://docs.grafana.org/reference/templating/#advanced-formatting-options)
Filter Option | Example | Raw | Interpolated | Description
The Prometheus datasource now support transforming Prometheus histograms to the heatmap panel. Prometheus histogram is a powerful feature, and we are really happy to finally allow our users to render those as heatmaps.
Prometheus query editor also got support for autocomplete of template variables. More information in the [Prometheus data source documentation](/features/datasources/prometheus/).
New enhancement includes support for filling in values for missing intervals and better precision handling and data type support for time columns. More information in the [PostgreSQL data source documentation](/features/datasources/postgres/#time-series-queries).
New enhancements includes support for filling in values for missing intervals, better precision handling and data type support for time columns and any column except time and metric is now treated as a value column. More information in the [MySQL data source documentation](/features/datasources/mysql/#time-series-queries).
Grafana v5.1 now ships with a built-in Microsoft SQL Server (MSSQL) data source plugin that allows you to query and visualize data from any Microsoft SQL Server 2005 or newer, including Microsoft Azure SQL Database. Have logs or metric data in MSSQL? You can now visualize that data and
define alert rules on it like any of our other data sources.
Same enhancements as described for PostgreSQL and MySQL are included in the MSSQL datasource.
Please read [Using Microsoft SQL Server in Grafana documentation](/features/datasources/mssql/) for more detailed information on how to get started and use it.
New enhancements includes support for multiple series stacking in histogram mode, thresholds for right Y axis, aligning left and right Y-axes to one level and additional units. More information in the [Graph panel documentation](/features/panels/graph/).
### Table Panel
New enhancements includes support for mapping a numeric value/range to text and additional units. More information in the [Table panel documentation](/features/panels/table_panel/#string).
