Feature Change
Illumio Core introduced the Explorer feature as a preview in Illumio Core 17.2.0. In Illumio Core 18.1.0, this feature became generally available. In Illumio Core 22.5.0 and 22.5.10, Illumio removed the Explorer feature from the PCE web console main menu.
Important
In Illumio Core 22.5.10+UI2, Illumio returned the Explorer feature to the PCE web console for customers who still want to use the functionality in that area of the GUI.
To access the original Explorer feature, upgrade from 22.5.x to Illumio Core 22.5.10+UI2.
In all Illumio Core 22.5.x releases, the functionality for the Explorer feature is available in the Table View and Mesh View in Illumination Plus.
Important
When you use the original Explorer feature, the functionality does not support the new Illumio Core 22.5 flexible label types feature, which allows you to create custom labels. The original Explorer feature only supports the standard Core RAEL labels. To use this functionality with the new flexible label types, you must use the Table View and Mesh View in Illumination Plus.
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.
