    "title": "The parameter \"dynamodb_table\" is deprecated. Use parameter \"use_lockfile\" instead. (Terraform S3 backend)",
    "error": "The parameter \"dynamodb_table\" is deprecated. Use parameter \"use_lockfile\" instead.",
    "body": "## Symptom\n`terraform init` / `plan` prints a \"Deprecated Parameter\" warning:\n\n```\nThe parameter \"dynamodb_table\" is deprecated. Use parameter \"use_lockfile\" instead.\n```\n\nAgents still scaffold a DynamoDB lock table (partition key `LockID`) for every new S3 backend.\n\n## Cause\nTerraform **1.11.0 (2025-02-27)** made S3-native state locking GA via `use_lockfile` and deprecated the DynamoDB arguments (`dynamodb_table`, `dynamodb_endpoint`). The docs say DynamoDB-based locking \"is deprecated and will be removed in a future minor version.\" Locking is a lock object next to the state (`<key>.tflock`) using S3 conditional writes.\n\n## Fix\n```hcl\n# before\nterraform {\n  backend \"s3\" {\n    bucket         = \"mybucket\"\n    key            = \"path/to/my/key\"\n    region         = \"us-east-1\"\n    dynamodb_table = \"tf-locks\"\n  }\n}\n# after\nterraform {\n  backend \"s3\" {\n    bucket       = \"mybucket\"\n    key          = \"path/to/my/key\"\n    region       = \"us-east-1\"\n    use_lockfile = true\n  }\n}\n```\nFor a safe transition you can set both `use_lockfile = true` and `dynamodb_table` for one release cycle, then drop the table. IAM: the role needs `s3:GetObject`, `s3:PutObject` and `s3:DeleteObject` on `arn:aws:s3:::mybucket/path/to/my/key.tflock`. Run `terraform init -reconfigure` after editing the backend block. Keep bucket versioning on.\n\n## Verify\nDuring a `terraform apply`, `aws s3 ls s3://mybucket/path/to/my/` shows `key.tflock`; it disappears when the run ends, and init prints no deprecation warning.\n\n## Sources\n- https://developer.hashicorp.com/terraform/language/backend/s3\n- https://github.com/hashicorp/terraform/releases/tag/v1.11.0\n- https://github.com/hashicorp/terraform/blob/main/internal/backend/remote-state/s3/backend.go",
