- Introduced `pkg6recv` for downloading packages from IPS repositories with support for recursive dependency fetching.
- Implemented CLI commands with `clap` for source/destination setup, package selection, and publisher defaults.
- Added `ConsoleProgressReporter` for detailed receive progress visibility.
- Enhanced the `Manifest` parser to support JSON format alongside IPS text format.
- Updated `FileBackend` and `RestBackend` repositories to fetch manifests and payloads in new operations.
- Extended `Digest` utilities for payload integrity checks.
- Added tests to verify basic functionality and manifest format preservation.
- Deleted the Jenkinsfile, transitioning all CI workflows to GitHub Actions.
- Added Illumos (OpenIndiana) build and release steps to GitHub workflows.
- Created a new release pipeline triggered by version tags starting with `v`.
- Updated README with release instructions using `cargo-release`.
- Expanded repository structure by introducing methods for fetching legacy catalogs, catalog file paths, and repository info.
- Added new REST API v1 endpoints for catalog, manifest, file, and publisher handling.
- Implemented `publisher` handler module with `get_publisher_v0` and `get_publisher_v1` methods to retrieve publisher details in pkg5 format.
- Updated `integration_tests` to validate new endpoints and ensure compatibility with legacy and modern catalog/manifest handling.
- Removed unused dependency `walkdir` and refactored test cases for clarity and efficiency.
- Deleted `pkg6dev` crate, including all related files (`src`, `Cargo.toml`, `Cargo.lock`, and `README.md`).
- Removed error handling, CLI logic, and publishing functionality from the project.
- Migrated relevant high-level APIs to `libips`, ensuring consistency with existing modules.
- Updated `libips` with a new `api` module to encapsulate `forge/pkgdev` integration logic.
- Simplified repository structure to exclude now-unused components and dependencies.
- Added `pkgtree` with functionalities to analyze dependency trees and detect cycles in IPS package images.
- Implemented CLI options for filtering by publisher, package substring, and output format (Tree/JSON).
- Integrated cycle detection and suggestions for resolving dependency cycles.
- Added testing support for cycle detection.
- Updated workspace dependencies and added `pkgtree` to the workspace configuration.
- Implement unit tests to cover `Image` creation, metadata management, saving/loading, and error handling.
- Add separate constructors for `Full` and `Partial` image types (`new_full`, `new_partial`).
- Introduce robust path handling methods (`metadata_dir`, `image_json_path`) for consistent metadata structure.
- Enhance error diagnostics with `InvalidPath` variant in `ImageError`.
- Update `Cargo.toml` for test module inclusion.
- Centralize package metadata in workspace for consistency.
- Upgrade `pkg6dev` and `pkg6repo` to version `0.5.1`, aligning with new workspace configuration.
- Introduce `EnvFilter` for dynamic logging configuration, defaulting to debug level.
- Add `LoggingEnvError` variant to `Pkg6DevError` with structured diagnostics for improved error handling.
