PRTG 22.3.79 is now available in the stable release channel! This version comes with the new **Microsoft 365 Mailbox sensor**, the new **FortiGate System Statistics sensor,** an update for **OpenSSL libraries,** **NetFlow sensors** with IPv6 support, and six more experimental **NetApp v2 sensors.**

Let's jump into the details:

## NEW: Microsoft Mailbox 365 sensor

The new [Microsoft 365 Mailbox sensor](https://www.paessler.com/manuals/prtg/microsoft_365_mailbox_sensor) monitors a folder of 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.

![microsoft-365-mailbox-sensor-paessler-prtg-overview-01](https://blog.paessler.com/hs-fs/hubfs/2022/Visuals/Body/microsoft-365-mailbox-sensor-paessler-prtg-overview-01.png?width=650&name=microsoft-365-mailbox-sensor-paessler-prtg-overview-01.png)

We introduced this sensor type as an [experimental sensor](https://blog.paessler.com/new-handling-of-beta-sensors-in-prtg-network-monitor) with the last PRTG version ([22.3.78](https://blog.paessler.com/prtg-version-22.3.78-is-now-available-in-the-stable-release-channel)) and implemented several improvements since then. You can now choose different folders in the mailbox, add a mailbox account from a different user by providing the user principal name of a shared mailbox in the Add Sensor dialog, and we enhanced the filter options.

## NEW: FortiGate System Statistics sensor

The new [FortiGate System Statistics sensor](https://www.paessler.com/manuals/prtg/fortigate_system_statistics_sensor) monitors the system health of a [Fortinet FortiGate firewall](https://blog.paessler.com/monitoring-fortigate-firewalls-with-paessler-prtg) and shows CPU and memory usage, as well as uptime, session statistics, and conserve mode activity.

This sensor was released as an [experimental sensor](https://blog.paessler.com/new-handling-of-beta-sensors-in-prtg-network-monitor) with PRTG version [21.4.73](https://blog.paessler.com/prtg-version-21.4.73-comes-a-new-user-interface-api-and-a-new-probe).

## Experimental: NetApp v2 sensors

With this release we introduce six more NetApp v2 sensors. Since NetApp is discontinuing their ONTAP, the sensors needed to be rewritten for the new ONTAP REST API. Additional to the [NetApp System Health v2 sensor](https://www.paessler.com/manuals/prtg/netapp_system_health_v2_sensor) in PRTG [22.1.75](https://blog.paessler.com/prtg-v-22.1.75-includes-a-new-netapp-sensor-improvements-and-fixes) and the [NetApp Volume v2 sensor](https://www.paessler.com/manuals/prtg/netapp_volume_v2_sensor) in PRTG [22.2.76](https://blog.paessler.com/prtg-v.-22.2.76-comes-with-okta-as-new-sso-provider-an-new-sensor-and-security-improvements), we now deliver the following experimental sensor types:

- NetApp LIF v2
- NetApp Aggregate v2
- NetApp NIC v2
- NetApp Physical Disk v2
- NetApp I/O v2
- NetApp LUN v2

The NetApp SnapMirror v2 sensor, the remaining NetApp sensor rewrite, will follow in the next PRTG release.

## ... and much more

The [NetFlow sensors](https://www.paessler.com/netflow_monitoring) are now able to listen for UDP packets on IPv6 addresses and [Modbus sensors](https://www.paessler.com/modbus-monitoring) support up to 10 values. We updated our **OpenSSL libraries** to version 1.0.2ze that patches [CVE-2022-1292](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2022-1292), improved the** security of the password transmission** method for several sensor types, and the script sensors support the usage of **placeholders for credentials**.

Also: **API keys** are now available for the classic PRTG API. You can use API keys as a parameter in any API call instead of the username and password or passhash.

For the Application Server, API keys will be available as of the next PRTG version.

With this release we fixed several bugs:

- The [FTP sensor](https://www.paessler.com/manuals/prtg/ftp_sensor) shows the up status again as defined when the login fails.
- The [SSL Certificate sensor](https://www.paessler.com/manuals/prtg/ssl_certificate_sensor) works again even when the endpoint requires client authentication

We improved the compatibility of [HTTP sensors](https://www.paessler.com/manuals/prtg/available_sensor_types#web) with certain web servers and fixed their SNI inheritance for hosts defined by IP address. We removed several **smaller memory leaks** and **failed login attempts are logged again **in the webserver log file.  
Please note that [EXE/Script sensors](https://www.paessler.com/manuals/prtg/available_sensor_types#exe) do not support **DLL files** anymore as of this release.

## Please also check our PRTG release notes

In summary, PRTG 22.3.79 includes 127 resolved issues, 30 implemented features and stories, 45 bug fixes and 52 completed tasks and to-dos. For all details, have a look at our [release notes page](https://www.paessler.com/prtg/history/stable#22.3.79.2108).
