What’s Changed

Release Notes

2026-07-14

• Keep hook subprocess parsing stable when Git diff customization or JVM environment-option announcements would otherwise alter captured output.
• Add --touched to format or check files changed on the current branch, including committed, staged, unstaged, and non-ignored untracked files.
• Support files, recursive directories, and glob patterns as explicit format and check targets. These respect global and per-tool path exclusions unless --force is passed.
