This article lists Atera Agent versions and a summary of what changed in each release.
2.5.28.0
August 2026
Devices on networks that only allow standard web traffic can now stay connected to Atera. The agent still uses its usual secure connection first, and automatically switches to the standard secure web port if that connection is blocked, so commands and IT automation keep working without firewall changes.
2.5.27.0
August 2026
Improved device registration details, so devices are identified in Atera by their installation, operating system, and agent version. This helps Atera troubleshoot setup issues faster.
2.5.26.0
August 2026
Fixed an issue where devices could remain Offline in Atera after a long internet outage until the Atera Agent service was restarted manually. The agent now restores its connection to Atera on its own once connectivity returns, so the device reports Online again without manual intervention.
2.5.25.0
August 2026
Agent installations on Windows, macOS, and Linux now carry a resettable per-account installation identifier, so Atera can confirm a new device was added with an authorized installer and block unauthorized agent installations. The identifier is kept out of installation and agent logs. Devices installed with an earlier installer keep working as before.
2.5.24.0
July 2026
Enriches MSI installer reporting payload, adding visibility into install failure causes (mainly running the installer without admin rights or without user consent).
2.5.21.0
June 2026
Minor improvements and refinements to the Windows installation experience.
2.5.19.0
June 2026
The agent can now sync its settings on demand when requested from Atera, so configuration changes take effect right away instead of waiting for the next scheduled sync.
2.5.18.0
Fixed an issue on Windows where the agent could stop reconnecting over its MQTT connection after the server certificate was rejected due to IoT service maintenance.
2.5.17.0
June 2026
Improved connection efficiency by making PubNub presence configurable, allowing presence tracking to be disabled to reduce unnecessary background network traffic.
2.5.16.0
Fixed an issue where changing the interval of a recurring package command did not take effect until the agent was restarted.
2.5.15.0
Fixed an issue where recurring package command execution was interrupted due to a parsing error. Fixed an issue where recurring package commands ran less frequently than their configured interval on machines that frequently sleep and resume.
2.5.14.0
Improved the cleanup process when removing the agent.
2.5.13.0
Improved MSI uninstall reliability - the installer now forcefully stops and removes the Atera Agent service during uninstall.
2.5.12.0
May 2026
Simplified golden image preparation and deployment - if the unique Agent ID is missing from the settings file, the agent now regenerates it automatically, allowing a single prepared image to be cloned across multiple devices without further reconfiguration.
2.5.11.0
The agent now stores the customer and folder identifiers locally during startup and settings sync.
2.5.10.0
April 2026
Added support for PubNub custom origin configuration, enabling agents to connect through alternative PubNub endpoints.
