Customer Impact:

• The Flexera Kubernetes agent can collect inventory for containers and images running on Flatcar Container Linux and correctly reports Flatcar as the operating system. This enhancement provides broader coverage for modern, container-optimized platforms, helping users manage assets consistently across Flatcar-based Kubernetes and standalone Flatcar instances.
• This release introduces a new ContainerD monitor (fnms-containerd-monitor) for the FlexNet agent on Linux. This enhancement provides broader coverage of containerized workloads and more accurate, configurable inventory data for Linux environments.
• The Lightweight Kubernetes Agent container is built to include a dedicated non-root user and runs the agent under this account by default. This enhancement provides improved security and better alignment with containerization best practices.
• The agent primarily uses the more accurate "Maximum Capacity of Pool" value, with "Active CPUs in Pool" used only as a fallback when needed. This enhancement provides more precise capacity data to support accurate pool capping calculations and licensing decisions.
• The FlexNet inventory agent now correctly communicates with a beacon when a new certificate revocation list (CRL) is published before the current CRL's stated expiry time.
• The FlexNet inventory agent now reports the correct processor capacity values for capped LPARs, providing a more accurate value for license consumption calculations.
• Fix for CRL file handling in FlexNet inventory agent on macOS. The agent no longer saves an empty (0 byte) CRL file.
• The FlexNet inventory agent now has a 60-second timeout for the disk space calculation. This should help with situations were the agent hanged or took too long when calculating disk space.
• The FlexNet inventory agent on Windows now excludes the directory C:\ProgramData\Microsoft\Windows\Containers from inventory collection.
• The FlexNet inventory agent now correctly removes the browser extensions when the agent is uninstalled.
• The FlexNet inventory agent now writes to file even if it has nothing to report to improve the troubleshooting experience.
• The uninstallation logic for the agent has been improved, so the process is much faster.
• The FlexNet inventory agent on Windows has been improved to fully suppress reboot behavior when files were in use, during an agent upgrade.
• The flxconfig component of the Flexera inventory agent on Unix systems now correctly uses a single timestamp format for all logs.
• The FlexNet inventory agent now correctly captures usage for RPM packages on Linux systems. 
• The libcurl, libxslt, github.com/sigstore/fulcio, github.com/containernetworking/plugins and golang.org/x/crypto third party libraries bundled with the FlexNet Inventory Agent have been updated in this release to address security vulnerabilities.
