***Plugin API**: Both datasource and panel plugin api (and plugin.json schema) have been updated, requiring an update to plugins. See [plugin api](https://github.com/grafana/grafana/blob/master/public/app/plugins/plugin_api.md) for more info.
***InfluxDB 0.8.x** The data source for the old version of influxdb (0.8.x) is no longer included in default builds, but can easily be installed via improved plugin system, closes [#3523](https://github.com/grafana/grafana/issues/3523)
***KairosDB** The data source is no longer included in default builds, but can easily be installed via improved plugin system, closes [#3524](https://github.com/grafana/grafana/issues/3524)
***Templating**: Templating value formats (glob/regex/pipe etc) are now handled automatically and not specified by the user, this makes variable values possible to reuse in many contexts. It can in some edge cases break existing dashboards that have template variables that do not reload on dashboard load. To fix any issue just go into template variable options and update the variable (so it's values are reloaded.).
### Enhancements
***LDAP**: Support for nested LDAP Groups, closes [#4401](https://github.com/grafana/grafana/issues/4401), [#3808](https://github.com/grafana/grafana/issues/3808)
