# What's New in Grafana v4.6

Grafana v4.6 brings many enhancements to Annotations, Cloudwatch & Prometheus. It also adds support for Postgres as metric & 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 datasource 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.
