[We've just released PRTG version 25.4.112](https://www.paessler.com/prtg/history/stable#25.4.112.1189) to the stable release channel. This version brings you the new [SNMP Linux Disk Free v2 sensor](https://www.paessler.com/manuals/prtg/snmp_linux_disk_free_v2_sensor), several security improvements, and updated language files for German and Spanish. [![prtg 25.4.112 is now available in the stable release channel](https://blog.paessler.com/hubfs/15_ARCHIVE/2019/visuals/header/header-new-prtg-release-2.png)](https://blog.paessler.com/prtg-25.4.112-is-now-available-in-the-stable-release-channel) Here are the new and improved features in this release: ## New sensor: SNMP Linux Disk Free v2 With this release, we introduce the [SNMP Linux Disk Free v2 sensor](https://www.paessler.com/manuals/prtg/snmp_linux_disk_free_v2_sensor) - the successor to the SNMP Linux Disk Free sensor. This enhanced sensor monitors the free space on disks of Linux/Unix systems via SNMP and is fully compatible with the Multi-Platform Probe, giving you more flexibility in your monitoring architecture. ## Additional improvements and fixes ### Sensor enhancements Beyond the new SNMP Linux Disk Free v2 sensor, we've updated the sensor schema to version 3 for several sensor types: ✅ [Script v2](https://www.paessler.com/de/manuals/prtg/script_v2_sensor) ✅ [SSH Script v2](https://www.paessler.com/de/manuals/prtg/ssh_script_v2_sensor) (BETA) ✅ [REST JSON Data](https://www.paessler.com/de/manuals/prtg/rest_json_data_sensor) (BETA) This schema update ensures support for setting channel limits, providing you with more control over your monitoring thresholds. We also fixed an issue with the [REST Custom v2 sensor](https://www.paessler.com/de/manuals/prtg/rest_custom_v2_sensor) for session-based authentication where the JSON path setting wasn't correctly processed, improving reliability for your API monitoring. ### Server improvements The Activation Token that we introduced with PRTG version 25.3.110 is now also displayed below the System ID on the License Status page when you select Manual (offline activation) for your license, making license management easier. We fixed an issue regarding Overload Protection where PRTG would incorrectly display the message "Warning! Overload protection is active!" even in cases when no Overload Protection was actually active. This resolves potential confusion in your system status assessment. [![New call-to-action](https://no-cache.hubspot.com/cta/default/2990530/d6c13a8d-4a60-4f6f-ac14-ae9b30909169.png)](https://cta-redirect.hubspot.com/cta/redirect/2990530/d6c13a8d-4a60-4f6f-ac14-ae9b30909169) ### PRTG API v2 enhancements API users now have expanded capabilities! You can now create [AWS Cost sensors](https://www.paessler.com/de/manuals/prtg/aws_cost_sensor) and [Cloud Ping sensors](https://www.paessler.com/de/manuals/prtg/cloud_ping_v2_sensor) via POST request on the endpoint */experimental/devices/{id}/sensor*. We've also delivered several fixes and improvements on other endpoints throughout the PRTG API v2. Additionally, we fixed an issue for the PRTG application server that occurred sporadically after updating to PRTG version 25.2.108. The server would occasionally crash and create a panic logfile with the message: "*panic: runtime error: invalid memory address or nil pointer dereference.*" This fix improves the overall stability of your PRTG installation. ### New UI improvements The new UI now offers several enhanced options for easier monitoring configuration: 🧩 You can now select a sensor as a dependency in the settings "*Schedules, Dependencies and Maintenance Windows*" 🧩 Set a Scanning Interval in device settings via a convenient drop-down menu 🧩 Configure what happens "*If a Sensor Scanning Fails*" with a new status option 🧩 Select device templates directly in the new UI of PRTG ## Check our PRTG release notes In summary, PRTG 25.4.112 includes 89 resolved issues, including 15 implemented features and stories, 26 bug fixes, 33 completed tasks & to-dos, and 14 finished documentation tickets. For all the details, take a look at our [release notes page](https://www.paessler.com/prtg/history/stable#25.4.112.1189). We also offer a [public roadmap of PRTG](https://www.paessler.com/prtg/roadmap) on our website, which we update 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. **Summary** PRTG 25.4.112 introduces the new SNMP Linux Disk Free v2 sensor for monitoring disk space on Linux/Unix systems, with full Multi-Platform Probe compatibility. We've updated the sensor schema to version 3 for several sensor types to support better channel limit configuration. The API now lets you create AWS Cost and Cloud Ping sensors, while the new UI offers improved dependency selection, scanning interval settings, and device template options for easier monitoring setup.  [All about PRTG](https://blog.paessler.com/topic/all-about-prtg) - [facebook](https://www.facebook.com/sharer.php?u=https://blog.paessler.com/prtg-25.4.112-is-now-available-in-the-stable-release-channel) - [twitter](https://twitter.com/share?count=none&original_referer=https://blog.paessler.com/prtg-25.4.112-is-now-available-in-the-stable-release-channel&url=&text=Prtg%2025.4.112%20is%20Now%20Available%20in%20the%20Stable%20Release%20Channel&via=PaesslerAG) - [linkedin](https://www.linkedin.com/shareArticle?mini=true&url=https://blog.paessler.com/prtg-25.4.112-is-now-available-in-the-stable-release-channel&title=&summary=&source=Paessler%20AG) - [mailto:?subject=Prtg%2025.4.112%20is%20Now%20Available%20in%20the%20Stable%20Release%20Channel&body=https://blog.paessler.com/prtg-25.4.112-is-now-available-in-the-stable-release-channel](mailto:?subject=Prtg%2025.4.112%20is%20Now%20Available%20in%20the%20Stable%20Release%20Channel&body=https://blog.paessler.com/prtg-25.4.112-is-now-available-in-the-stable-release-channel) [![Stay ahead of IT infrastructure issues with Paessler PRTG](https://no-cache.hubspot.com/cta/default/2990530/interactive-185175445344.png)](https://blog.paessler.com/hs/cta/wi/redirect?encryptedPayload=AVxigLJoXQ91gpfgS8oBBGussv4GDO2rE6jIBlyYz8BqIZDbW1NWC%2BR5mAmmCl3lklGQnmBqTegxBF3iNpsgOjpPAF%2BNnXTFOnzLe6ksrWfRFEYPlTw3innpxTBkdKzEXfw%2FGH3Uc5NzUkL6aQxqK37RxITJxRrWWvKE%2B10IFLmEPQQ%2BW90zp%2B9gQYv35g%3D%3D&webInteractiveContentId=185175445344&portalId=2990530) ***Please note:** we are currently experiencing problems with our comments form.
