Here’s the explanation from HCL:
The Update VM Manager Tool to version (10.0.7.0) was failing. We fixed the fixlet source code related to the issue, so our deployment scripts were released with a newer version of the fixlet (10.0.7.1). However, it contains only the changes to the fixlet code; no changes to the VM Tool build itself.
To summarize, the latest version of the VM Manager Tool is still 10.0.7.0. Thus, if you are already running VM Manager Tool v10.0.7.0, your Update VM Manager Tool to version (10.0.7.1) fixlet will show as not relevant; no action is needed.
