@a-b I noticed that the latest plugin version is still missing here https://plugins.cloudfoundry.org/

Actually, the result of the last PR (#375) is also still missing here. Is there something broken in the CI/CD pipeline?

[a-b]

Thanks for reporting!

We will take a look and get back to you shortly. I suspect this has something to do with broken CD related to the recent migration of our infrastructure.

@a-b I'm sorry to bother you. Do you have any news on this?
