Important
Classic UI Removed
In Illumio Core 23.2.0, Illumio introduced a new PCE user interface (UI) designed to maximize user productivity and enable intuitive platform administration. Users had the option to toggle between the new UI and the earlier, classic UI.
In 23.5, the toggle option is removed. The classic UI is no longer available.
End of Support
Illumio REST API v1
The version 1 of Illumio REST APIs (API v1) is not supported effectively with the 21.1 and later releases. Illumio recommends that you upgrade to API v2.
Internet Explorer 11
Illumio Core 19.1 was the last release to support Internet Explorer 11. Internet Explorer 11 is no longer supported in Illumio Core 19.2 and later releases. Illumio recommends Chrome, Edge, or Firefox for use with the PCE web console.
Organization Events
Since the 19.1.0 release, the older form of events, known as “audit or organization events,” is no longer supported or available.
Any versions of the former SIEM Integration Guide that are earlier than version 18.2.1 are valid only for their corresponding versions, not version 18.2.1 or later releases.
Customers should upgrade to the latest version of Illumio Adaptive Security and take advantage of the newly designed auditable events.
