Version 1.2.344 Release Notes

This release improves extension-to-agent communication, especially for Mac agent support and license-state handling.

What’s New

Added support for the Mac agent license activation flow through the browser extension.
The extension now forwards fuller agent state information to the web app, including license status, so the app can more accurately detect whether the agent is installed, connected, and licensed.
Added Mac platform support behind a feature flag.

Improvements

Improved reliability of license checks after gateway license allocation by explicitly forwarding them through the extension.
Restored Safari extension configuration values in web app environment files.
Cleaned up a few implementation details from review, including safer runtime port handling and clearer license-check flow code.
