The latest version of PRTG comes with the new **AWS RDS v2 sensor**, which leaves beta status and is now fully supported, and the experimental **Microsoft 365 Mailbox** sensor, which is compatible with OAuth2.

Let's have a look at some more details!

## New: AWS RDS v2 sensor

The [AWS RDS v2 sensor](https://www.paessler.com/de/manuals/prtg/aws_rds_v2_sensor) monitors the performance of a Relational Database Service (RDS) database by reading its data from Amazon CloudWatch via the AWS API. This sensor requires [credentials for AWS](https://www.paessler.com/de/manuals/prtg/device_settings.htm#cloudcredentials) in a device higher in the [object hierarchy](https://www.paessler.com/de/manuals/prtg/object_hierarchy) (for example, in the settings of the parent device), as well as the [permissions](https://www.paessler.com/de/manuals/prtg/aws_rds_v2_sensor.htm#reqs) for the AWS API key.

[![AWSRDSsensor](https://blog.paessler.com/hs-fs/hubfs/AWSRDSsensor.png?width=650&name=AWSRDSsensor.png)](https://blog.paessler.com/hubfs/AWSRDSsensor.png)

We released this sensor type as experimental sensor with [PRTG 21.3.71](https://blog.paessler.com/paessler-prtg-21.3.71-with-new-iot-aws-and-redfish-sensors). It was the last AWS v2 sensor in experimental status. Now that all sensor types of the new AWS v2 sensor family are stable, we also announce theupcoming **deprecation of all the old Amazon CloudWatch sensors **as of PRTG version .81.

## Experimental: Microsoft 365 Mailbox sensor

The [experimental](https://blog.paessler.com/new-handling-of-beta-sensors-in-prtg-network-monitor) Microsoft 365 Mailbox sensor monitors a Microsoft 365 mailbox. The sensor shows the number of emails in the mailbox, the age of newest and oldest emails, and it provides several filter options.

[![PRTGMicrosoftMailboxSensor](https://blog.paessler.com/hs-fs/hubfs/PRTGMicrosoftMailboxSensor.png?width=650&name=PRTGMicrosoftMailboxSensor.png)](https://blog.paessler.com/hubfs/PRTGMicrosoftMailboxSensor.png)

The [Microsoft 365 Mailbox sensor](https://www.paessler.com/manuals/prtg/microsoft_365_mailbox_sensor) authentication option is based on [OAuth2](https://oauth.net/2/). Microsoft is retiring basic authentication starting in October 2022, and IMAP and POP3 including Roundtrip sensors will stop working accordingly, so we are introducing this sensor to be ahead of the deprecation for basic authentication.

## New UI: Resizable split-screen mode

The device tree in our new UI is now equipped with a split-screen mode that is also resizable. The view is split into a navigation tree and the subpages of the selected objects.

## ... and many more

We fixed several prominent bugs with PRTG 22.3.78. The **[FTP sensor](https://www.paessler.com/manuals/prtg/ftp_sensor),** for example, can handle connections during the authentication step again where it failed in the previous version. **[Cloud HTTP v2](https://www.paessler.com/manuals/prtg/cloud_http_v2_sensor) and [Cloud Ping v2](https://www.paessler.com/manuals/prtg/cloud_ping_v2_sensor)** sensors come with stability improvements, while the Cloud HTTP v2 sensor now can also inherit the proxy settings for HTTP sensors. And **SSH sensors** support a broader range of older encryption algorithms again.

## Please also check our PRTG release notes

In summary, PRTG 22.3.78 includes 105 resolved issues, 25 implemented features and stories, 40 bug fixes and 40 completed tasks and to-dos. For all details, have a look at our [release notes page](https://www.paessler.com/prtg/history/stable#22.3.78.1873).

We also offer a [public roadmap of PRTG](https://www.paessler.com/prtg/roadmap) on our website and we update it regularly. There you can read which features we are currently working on and what kind of things we want to implement in PRTG in the future.
