This is an update for whose having the same problem (some broken pipelines after the update).
Here the first answer of support:
I have checked and verified this internally.
Horizon has been sold as a product by Broadcom and it's not part of PowerCLI anymore. Hence, we have removed this module from the PowerCLI.

We no no longer support this module in PowerCLI.
Please let me know if you have any follow-up queries.
Is this real? How is is possible that a so important API has been removed without any announce?
Omnissa and Broadcom had announced that the collaboration would be stay to further support the whole VMware ecosystem, but this proves the contrary...
Has anyone other information?
