We are now maintaining this TA to ensure its vetted and continues to parse (https://splunkbase.splunk.com/app/4238/) .
We have a few updates happening over the next few days, so, please wait before downloading it .. but.. it is working well and vetted for cloud.
Are you saying that Enosys has taken responsibility for the existing Add-on? Is there any confirmation of that handover from Splunk Inc.? Or is your effort a fork of the existing package? Or a de-novo parallel implementation?
I spoke to Splunk Support and they said they had the intention of reviewing it but they have not gotten to it yet. I had not gotten a follow up response on it but I am sure it will happen.
