February 2026: Delivered a safety-focused enhancement to oracle/terraform-provider-oci by introducing an environment variable, TF_PRESERVE_STATE_ON_404, to preserve the Terraform state when a 404 Not Found/Not Authorized occurs during CRUD operations. This prevents inadvertent resource deletions and keeps the Terraform state in sync with real infrastructure. The change reduces risk for users who encounter partial permissions or edge-case API responses, and aligns provider behavior with security expectations. Implemented via commit dfa00958d988978ab462cdaa9a47f4e2fdf051f0, addressing related tickets TER-8748, TER-8666, TOP-9162.
