Sorry for the confusion. Let me try to explain.
Because TIE and DXL are separate products, they will not always be released at the same time. This is the case with the 1.1 release. TIE 1.1 released, but DXL 1.1 has not yet.
However, for the TIE 1.1 release there is a dependency on the DXL 1.1 extensions so those were made available for TIE. The DXL 1.1 Broker & Client will be made available at a later time.
This information was also specified in the TIE Known Issues KB article that is referenced in the Release Notes and also here - https://kc.mcafee.com/corporate/index?page=content&id=KB84127
I hope that helps.
You know, I read through that KB article but I must have missed that section right at the top.
I dug a bit more yesterday and I found this: Threat Intelligence Exchange Getting Started Guide
This document seems to be a bit clearer w.r.t what needs to be installed.
i figured out one important thing.
When upgrading TIE from version 1.0 to version 1.1 the DXL Broker is not updated to version 1.1. This results in some limitations like a non working Data Exchange Layer Fabric overview.
From my side, i would suggest reinstalling TIE server or installing a fresh Slave server to preserve the TIE database.
