# What's New in Grafana v6.2
|
||||
|
||||
> More content will be added to this guide before the stable release.
|
||||
|
||||
For all details please read the full [CHANGELOG.md](https://github.com/grafana/grafana/blob/master/CHANGELOG.md)
|
||||
|
||||
If you use a password for your datasources please read the [upgrade notes](/installation/upgrading/#upgrading-to-v6-2).
|
||||
|
||||
## Improved security
|
||||
|
||||
- Ensure encryption of datasource secrets
|
||||
- Embedding Grafana not allowed per default
|
||||
- Disable browser caching for full page requests
|
||||
|
||||
## Provisioning
|
||||
|
||||
- Environment variables support, see [Using environment variables](/administration/provisioning/#using-environment-variables) for more information.
|
||||
- Reload provisioning configs, see [Admin HTTP API](/http_api/admin/#reload-provisioning-configurations) for more information.
|
||||
- Do not allow deletion of provisioned dashboards
|
||||
- When trying to delete or save provisioned dashboard, relative file path to the file is shown in the dialog.
|
||||
|
||||
## Official support for Elasticsearch 7
|
||||
|
||||
Grafana v6.2 ships with official support for Elasticsearch v7, see [Using Elasticsearch in Grafana](/features/datasources/elasticsearch/#elasticsearch-version) for more information.
|
||||
|
||||
## Bar Gauge Panel
|
||||
|
||||
Grafana v6.2 ships with a new exciting panel! This new panel, named Bar Gauge, is very similar to the current
|
||||
Gauge panel and shares almost all it's options. The main difference is that the Bar Gauge uses both horizontal and
|
||||
vertical space much better and can be more efficiently stacked both vertically and horizontally. The Bar Gauge also
|
||||
comes with 3 unique display modes, Basic, Gradient, and Retro LED. Read the
|
||||
[preview article](https://grafana.com/blog/2019/04/11/sneak-preview-of-new-visualizations-coming-to-grafana/) to learn
|
||||
more about the design & features of this new panel.

|
||||
|
||||
## Improved table data support
|
||||
|
||||
We have been working on improving table support in our new react panels (Gauge & Bar Gauge) and this is ongoing work
|
||||
that will eventually come to the new Graph & Singlestat & Table panels we are working on. But you can see it already in
|
||||
the Gauge and Bar Gauge panels. Without any config, you can visualize any number of columns or choose to visualize each
|
||||
row as its own gauge.
|
||||
|
||||
## Lazy loading of panels out of view
|
||||
|
||||
This has been one of the most requested features for many years and is now finally here! Lazy loading of panels means
|
||||
Grafana will not issue any data queries for panels that are not visible. This will greatly reduce the load
|
||||
on your data source backends when loading dashboards with many panels.
|
||||
|
||||
## Panels without title
|
||||
|
||||
Sometimes your panels do not need a title and having that panel header still take up space makes singlestats and
|
||||
other panels look strange and have bad vertical centering. In v6.2 Grafana will allow panel content (visualizations)
|
||||
to use the full panel height in case there is no panel title.

||||

||||

||||
## Minor Features and Fixes
|
||||
|
||||
This release contains a lot of small features and fixes:
|
||||
|
||||
- Explore - Adds user time zone support, reconnect for failing datasources and a fix that prevents killing Prometheus instances when Histogram metrics are loaded.
|
||||
- Alerting - Adds support for configuring timeout durations and retries, see [configuration](/installation/configuration/#evaluation-timeout-seconds) for more information.
|
||||
- Elasticsearch - A small bug fix to properly display percentiles metrics in table panel.
|
||||
- InfluxDB - Support for POST HTTP verb.
|
||||
- CloudWatch - Important fix for default alias disappearing in v6.1.
|
||||
- Search - Works in a scope of dashboard's folder by default when viewing dashboard
|
||||

||||
