We just published patch release 2 for version 6.2. Important changes since release 6.2.1:

-   Added subagent for reading electricity grid data (including carbon intensity) from ENTSO-E Transparency Platform
-   Added subagent for reading weather and solar forecast data from open-meteo.com
-   Device configuration backup support for HPE ProCurve, HPE Comware, and Aruba switches
-   New "scripted gauge" dashboard element
-   Agent checks available disk space before starting upgrade
-   Number of attempts to deploy a software package is now limited
-   Agent connect timeout on the server side is now configurable
-   Number of crash dumps kept on disk can be limited
-   File manager improvements: folders expand on double-click, view state preserved on manual refresh
-   Fixed remotely triggerable stack buffer overflow, heap over-read, and memory leak in NTCB module packet parser
-   Fixed authenticated memory corruption in client session (CMD\_MODIFY\_NODE\_DCI)
-   Fixed agent communication freeze caused by socket descriptor reuse race in communication channel close
-   Fixed thread pool starvation that could make agent unresponsive when all worker threads are blocked
-   Fixed deadlock in logwatch subagent
-   Fixed creation of duplicate ::/64 subnets on every configuration poll
-   Updated bundled libcurl in Windows installers to 8.21.0 (fixes CVE-2026-8927)
