Discovery Hidden By Default

Discovery commands discover hidden configurations by default

The find and list commands now discover units/stacks in hidden directories by default (this previously required usage of the --hidden flag), notably this now discovers .terragrunt-stack directories by default. The commands also now support an opt-in --no-hidden flag to avoid discovery in hidden directories.

The --hidden flag has been deprecated, and will not be removed in 1.0. Using the flag no longer does anything.
