Terragrunt 0.97
This overview applies to target Terragrunt versions of at least 0.97.
Filtering
Completed experiment: filter-flag graduated, making --filter and --filters-file generally available. Filter expressions form the unified selection API for paths, exclusions, reading relationships, external dependencies, and graph traversal; legacy queue flags remain compatibility aliases.
The deprecated --units-that-include flag became an alias for the reading= filter. The deprecated --queue-strict-include flag became a no-op because selected units no longer automatically include their dependencies.
Breaking behavioural change: a trailing ** in CLI globs matches all paths, completing the double-star strict control.
Within terragrunt.stack.hcl, get_original_terragrunt_dir() resolves to the stack file's directory even when another configuration reads it.
