After the Terraform Registry revamp we seem to have lost admin/resync access to the aliyun/alibabacloudstack provider namespace

Terraform Providers

Hi Terraform Registry team,

We maintain the `aliyun/alibabacloudstack` provider on the Terraform Registry. We have two questions we’d appreciate help with.

Background

We were previously granted admin/management access to this provider’s namespace via HashiCorp support ticket #148934. Since the registry UI revamp, we appear to have lost that access — we can no longer trigger a manual resync from the provider settings page.

1. Version sync is broken — two GitHub releases are missing from the registry

Two recent releases in our GitHub repository (aliyun/terraform-provider-alibabacloudstack) have never appeared on the registry:

Version On GitHub On registry
v3.18.30 :white_check_mark: released :cross_mark: not found (404 via the registry API)
v3.18.31 :white_check_mark: released 2026-08-03 :cross_mark: not found (404 via the registry API)

Both releases follow the standard publishing process (release assets contain the multi-platform zip files, SHA256SUMS, and .sig signature files), so we don’t believe there is anything wrong with the release artifacts themselves. The highest 3.18.x version currently visible on the registry is 3.18.29.

Our questions:

  • Could you restore our namespace admin access (or advise whether we should now claim/manage the aliyun namespace through the new HCP Terraform Public Namespaces feature)?
  • Could you trigger a resync for this provider, or advise us to check/recreate the GitHub release webhook, so that 3.18.30 and 3.18.31 get published?

2. How do we remove/unpublish provider version 3.19.0?

Per our company’s sales strategy, all changes from 3.19.0 have been fully backported to the 3.18.x series. We therefore want to remove version 3.19.0 from the registry so that users stay on the maintained 3.18.x line.

We understand from the registry FAQ that there is no self-service process for deleting a provider version (unlike modules). Could you clarify:

  • What is the correct channel to request removal — a support ticket, email, or an issue in the hashicorp/terraform-registry-support repository?
  • Would the “delete version” option available via Public Namespaces apply in our case?

Any guidance on the process and expected turnaround time would be greatly appreciated. Thanks in advance!
