# What's new in Grafana v4.6

Grafana v4.6 brings many enhancements to Annotations, Cloudwatch and Prometheus. It also adds support for Postgres as metric and table data source!

### Annotations

{{< docs-imagebox img="/img/docs/v46/add_annotation_region.png"  max-width= "800px" >}}

You can now add annotation events and regions right from the graph panel! Just hold Ctrl/Cmd+Click or drag region to open the **Add Annotation** view. The
[Annotations]({{< relref "../reference/annotations.md" >}}) documentation is updated to include details on this new exciting feature.

### Cloudwatch

Cloudwatch now supports alerting. Setup alert rules for any Cloudwatch metric!

### Postgres

Grafana v4.6 now ships with a built-in data source plugin for Postgres. Have logs or metric data in Postgres? You can now visualize that data and
define alert rules on it like any of our other data sources.

### Prometheus

New enhancements include support for **instant queries** and improvements to query editor in the form of autocomplete for label names and label values.
This makes exploring and filtering Prometheus data much easier.
