here are the details about the latest prtg release

iPlease Note

With PRTG version 23.2.83 we announce the limitation of NetApp v1 sensors. You can still add these sensor types to your PRTG but they will stop working when you update to ONTAP version 9.13.1.

Let's jump into the details!

Improved: Update to Open SSL 1.1.1

The release includes an update to OpenSSL version 1.1.1t, to support TLS 1.3 in the Probe Connection and PRTG Web Server connections (for High, Default and Weakened security connection options).

Important: Please note concerning your running HTTP sensors that we do not support any cryptographically broken ciphers for outgoing HTTP connections anymore with this update to OpenSSL 1.1.1t due to security reasons. This concerns the encryption methods MD5, DES, RC4.
If you run any HTTP sensors for devices that do not offer any ciphers supported by OpenSSL 1.1.1t anymore, the sensors may run into an error with the message ssl3_read_bytes:sslv3 alert handshake failure.

TLS 1.3 is the latest version of the TLS protocol that is used by HTTPs and other protocols for encryption. This also enables TLS 1.3 for the Notification Delivery method type for the use of SMTP relay servers. You can now select TLS 1.3 as an SSL/TLS method:

OpenSSL_111_Connection_SecurityWith this change, we also improved the sensor types SSL Security Check sensor and HTTP Push sensors to support TLS 1.3 as well.

PRTG Sensor SSL Security Check

... and much more

With this version we also deliver a new Python distribution, 3.9.13, that includes security patches and several other improvements. You need to consider this change when you run the Python Script Advanced sensor.
We also updated our reporter engine to Chromium version 89, which will improve the rendering of PDF reports that did not work properly in certain cases before.

New call-to-action

Additionally we improved the Microsoft Azure Subscription Cost sensor to support the new Azure billing model from Microsoft. The new Azure billing model creates invoices for calendar months instead of individual billing periods and Microsoft also introduced new billing profiles, which was a reason why you probably received empty billing periods before. 

We also released several important fixes with this version. In PRTG version 23.1.82 we reported known issues with PDF reports that were not displayed when logging in with Single-Sign On and email notifications due to the encoding of the subject not working correctly for diacritics and special characters.

Furthermore we hardened PRTG against a possible Cross-Site Scripting (XSS) attack and we deliver a fix that patches a CVE vulnerability (CVE-2022-35739).
