Agent 2.6.53 Release Notes

Summary

Agent 2.6.53 is a patch release, and includes the all additions, improvements, and bugfixes included in Agent 2.6.49 Release Notes, as well as the following improvements:

Fixes and Improvements

  • Reduced unnecessary reconnects during long-running sessions - Previously, the Agent's real-time connection would periodically drop and fully re-establish itself even while the connection was otherwise healthy, because the Agent wasn't refreshing its session credentials proactively. The Agent now refreshes its session in the background before it expires, so healthy connections stay up longer without unnecessary interruptions.
  • Faster, cleaner recovery from connection issues - In some cases, the Agent could attempt to reconnect before it had a valid session credential ready, resulting in a connection that the server would reject after a delay rather than retrying immediately. The Agent now checks that it has a valid credential before each reconnect attempt, so failed attempts are detected and retried faster instead of stalling.
  • Device Data + Inventory - Fixed a timing issue where a small number of inventory checks could be missing from the very first report after an Agent restart (they would appear normally on the next cycle).
  • Custom Script Result Code - Windows custom script executions now report their actual exit code instead of always returning code 124.
  • High CPU Utilization on macOS for Users not in Staff Group - Fixed an IPC error between the Tray and Agent that would cause the Tray Service to over-consume CPU bandwidth if the macOS user account was not a member of the Staff group.
  • Custom Agent Icon Management - This release re-addresses a defect related to setting and resetting the Custom Icon feature added in Agent 2.5. The original fix was delivered in Agent v2.5.70, but was inadvertently excluded from the initial v2.6.49 release.

Security Improvements

  • Hardened integrity verification for a bundled Windows component installer.
  • Tightened access controls on a local diagnostic interface on macOS.
  • Improved documentation and governance controls around a required local macOS service account.
