Most agents update to it automatically. πŸ”ƒ **Changes** - AI detection capabilities have been improved with updated detection checks for model files. [LAN-20328] πŸ› **Fixes** - Fixed the issue where an IT Agent upgraded to v4.13.5 could scan other devices on the local network instead of only the device it's installed on. [LAN-21683] - Fixed an issue where assets were not created for newly installed IT Agents due to a scanning target lookup failure. [LAN-18598] - Fixed an issue where the IT Agent could stop working after a network change on machines with certain network adapter configurations. [LAN-21230] ## July 30, 2026 β€” v4.13.5 Resolved in v4.13.6 IT Agent 4.13.5 was rolled back within 18 hours because an upgraded agent could, under a specific timing condition, scan other devices on the local network instead of only the device it's installed on. This was not a security incident, and no outside party was involved. It is fixed in v4.13.6. Most agents update to v4.13.6 automatically within a few days. Updates are managed through update groups; see [Update IT Agent Discovery](/docs/update-it-agents). **How to tell if you were affected:** check any machine that ran the IT Agent before it updated to v4.13.6 for these three signs: - A security alert describing scan or port sweep traffic from that machine. - An Npcap packet capture driver that no one installed. - Scanning that continued even after you restarted the agent. If you see any of these, [contact Lansweeper Support](https://support.lansweeper.com/s/contactsupport) and we'll help directly. If none of this sounds familiar, you weren't affected and no action is needed. ## June 30, 2026 β€” v4.12.13 πŸ”ƒ **Changes** - The IT Agent now reuses its cloud connection across check-ins instead of reconnecting each time, significantly reducing DNS lookups and connection overhead.
