We just released Terragrunt 1.0.

Notable updates:

- Terragrunt Stacks. A modern way to define higher-level infrastructure patterns, reduce boilerplate, and manage large estates without losing independently deployable units.

- Streamlined CLI. A less verbose, more consistent; `run` replaces `run-all`, and new commands `exec`, `backend`, `find`, and `list`.

- Filters `--filter`. One targeting/query system to replace several older targeting flags, plus new capabilities for selecting units/stacks.

- Performance improvements, especially if you’re upgrading from older Terragrunt versions, and automatic shared provider cache when using OpenTofu ≥ 1.10.

- And an explicit backwards compatibility guarantee. Gruntwork is making a formal commitment to backwards compatibility for Terragrunt across the 1.x series.
