## Inspect queries in Explore
You can enjoy all the details query inspector gave you in dashboards now in Explore as well. You can open query inspector tab with the button next to query history. See [Query inspector in Explore]({{< relref "../features/explore/index.md#query-inspector" >}}) for more details.
## \$\_\_rate_interval for Prometheus
You can now use the new variable `$__rate_interval` in Prometheus for rate functions mainly. `$__rate_interval` in general is one scrape interval larger than `$__interval` but is never smaller than four times the scrape interval (which is 15s by default). See the [Prometheus data source]({{< relref "../features/datasources/prometheus.md#using-__rate_interval-variable" >}}) for more details.
## Toggle parsed Loki fields
With this awesome contribution from one of our community members, you can now toggle parsed fields in Explore.

Alert notification channels now store sensitive settings and secrets, such as API tokens and passwords, encrypted in the database.
