     We strongly encourage planning to migrate to a newer version of Windows rather than relying on these workarounds for the long term, because the Terraform team will test future releases only on up-to-date Windows 10 and can therefore not guarantee ongoing support for older versions.
     
 * Interrupting execution will now cause terraform to exit with a non-zero exit status. ([#26738](https://github.com/hashicorp/terraform/issues/26738))
+* The trailing `[DIR]` argument to specify the working directory for various commands is no longer supported. Use the global `-chdir` option instead. ([#27664](https://github.com/hashicorp/terraform/pull/27664))
+
+    For example, instead of `terraform init infra`, write `terraform -chdir=infra init`.
 * The `-lock` and `-lock-timeout` options are no longer available on `terraform init` ([#27464](https://github.com/hashicorp/terraform/issues/27464))
 * The `-verify-plugins=false` option is no longer available on `terraform init`. (Terraform now _always_ verifies plugins.) ([#27461](https://github.com/hashicorp/terraform/issues/27461))
 * The `-get-plugins=false` option is no longer available on `terraform init`. (Terraform now _always_ installs plugins.) ([#27463](https://github.com/hashicorp/terraform/issues/27463))
