# Terragrunt 0.88

This overview applies to target Terragrunt versions of at least 0.88.

## Explicit command forwarding

Breaking change: unknown top-level commands are no longer forwarded to OpenTofu or Terraform. Supported shortcuts such as `terragrunt plan` remain; other delegated commands use `terragrunt run -- <command>`.

```text
terragrunt run -- workspace ls
terragrunt run -- graph
terragrunt run --all -- plan -var foo=bar
```

The `--` separator distinguishes delegated arguments. Command-specific Terragrunt flags follow the command that owns them; for example, `terragrunt run --all --provider-cache plan`.

The `backend-bootstrap`, `backend-require-bootstrap`, `disable-bucket-update`, and `feature` flags became command-scoped on the supported commands rather than global flags.
