# What's new in Grafana v2.1
##More Dynamic Dashboards
The Templating system is one of the most powerful and well-used features of Grafana. The 2.1 release brings numerous improvements that make Dashboards more dynamic than ever before.
Grafana 2.1 brings improvements in three core areas: dashboarding, authentication, and data sources.
As with every Grafana release, there is a whole slew of new features, enhancements, and bug fixes. To see everyting

### Multi-Value Template Select
Multi-Value Select allows for the selection of multiple template variables.
These variables can be used in any Panel to make them more dynamic, and automatically show only the desired data.
Multi-Value Select is also a basis for enabling Repeating Rows and Repeating Panels.

### Multi-Value Template Variables
A template variable with Multi-Value enabled allows for the selection of multiple values selected at the
same time. These variables can then be used in any Panel to make them more dynamic, and to give you the perfect view of
your data. Multi-Value variables is also enabling the new Row repeat and Panel repeat feature described below.

Any Row or Any Panel can be configured to repeat (duplicate itself) based on the Multi-Value Template variables selected.

### Basic Auth support
### Basic Auth Support
You can now authenticate against the Grafana API utilizing a simple username and password with basic HTTP authentication.
> ***Note:*** This can be useful for provisioning and config management systems that need to utilize the API without having to create an API key.

### User authentication utilizing headers
### Auth Proxy Support
You can now authenticate utilizing a header (eg. X-Authenticated-User, or X-WEBAUTH-USER)
> ***Note:*** this can be useful in situations with reverse proxies.
### New “Read-only Editor” User Role
There is a new User role available in this version of Grafana: “Read-only Editor”. This role behaves just like the Viewer role does in Grafana 2.0.
That is you can edit graphs and queries but no save dashboards. The Viewer role has been modified in Grafana 2.1 so that users assigned this role
can no longer edit panels.

## Improved data source support
## Data source Improvements
### Improved Data Sources
We continue to make progress on fully supporting InfluxDB 0.9, but it has proven to be a bit of a moving target. This Grafana release brings a much improved query editor for InfluxDB 0.9
### InfluxDB 0.9 Support
Grafana 2.1 now comes with full support for InfluxDB 0.9. There is a new query editor designed from the start
for the new features InfluxDB 0.9 enables.

### OpenTSDB Data Source improvements
Grafana now supports template variable values lookup queries, as well as limiting tags by metric
Grafana OpenTSDB data source now supports template variable values queries. This means you can create
template variables that fetches the values from OpenTSDB (for example metric names, tag names, or tag values).
The query editor is also enhanced to limiting tags by metric.
> ***Note:*** OpenTSDB config option tsd.core.meta.enable_realtime_ts must enabled for OpenTSDB lookup api)
### New Data Source: KairosDB
Experimental support for the KairosDB is now shipping in Grafana. Thank you to < > for their hard work in getting it to this point.
The Cassandra backed time series database KairosDB is now supported in Grafana out of the box. Thank you to

## Panel Improvements
Grafana 2.1 gives you even more flexibility customizing how individual panels render.
Overriding the colors of specific series using regular expressions, changing how series stack,
and allowing string values will help you better understand your data at a glance.
