v7.0.0 (2026-08-22)

Release Notes

Breaking changes

• Rebuilt HawkEye as one hawkeye crate that provides both the Rust library and command-line application; the hawkeye-fmt crate and its v6 APIs are not preserved.
• Replaced the v6 camel-case config with a strict snake-case schema organized around header, files, props, git, styles, and ordered rules.
• Removed v6 compatibility switches, default exclude lists, configurable detection regexes, and the repository-specific GitHub Action.
• Changed edit commands to succeed after making changes by default. Use check in CI or pass --fail-on-change to format and remove.
• Replaced command-specific JSON files with one report schema written to stdout by --output-format json; logs and errors are written to stderr.
• Defined Git creation as the latest addition in the current exact-path lifetime. Delete-and-recreate and rename-to-a-new-path start new histories.

New features

• Added a public Config, Engine, Scope, report, and pending-edit API.
• Added safe header replacement with explicit conflict reporting, literal line and block styles, and distinct accepted-input and canonical-output styles.
• Added positional file and directory selection for check, format, and remove, including staged-file support in pre-commit hooks.
• Added in-process Git discovery and file attributes through gix, including merge-aware history traversal without requiring a git executable.
• Added human and JSON reports, stable exit-code categories, debug logging, and deterministic preservation of common file preambles and line endings.
• Added cargo-binstall archives, a distroless multi-architecture container image, and Python and Docker pre-commit hooks.

6.5.0 2026-02-09

Release Notes

Notable changes

• Minimal Supported Rust Version (MSRV) is now 1.90.0.

Bug fixes

• hawkeye CLI now uses hawkeye-fmt of exactly the same version to format headers, instead of using the latest version of hawkeye-fmt that may not be compatible with the current version of hawkeye.

Improvements

• Replace anyhow with exn for more informative error messages.
