# Terragrunt 0.98

This overview applies to target Terragrunt versions of at least 0.98.

## Filtering and exits

The `--filter` flag now implies `--all`, so a filtered command automatically uses multi-unit orchestration.

For delegated `plan -detailed-exitcode` runs, `run --all` returns the highest error code when any unit returns 1 or greater than 2; otherwise any drift result yields 2, and no drift yields 0.

Git-plus-graph filter combinations and negative-only filters were corrected. Destroy plan files are passed to OpenTofu or Terraform in the accepted argument order.

## Release verification

Terragrunt release assets gained GPG and Cosign signatures. This affects binary verification and does not change managed infrastructure behaviour.
