About:
git-when-merged is a command-line utility that determines the merge commit(s) that incorporated a specific commit into a target branch. It solves the common Git problem of tracing when and how a commit from one branch was integrated into another, which is particularly useful for complex histories with rebasing or multiple merge paths.

Key Features:

Identifies the exact merge commit(s) that brought a commit into a target branch
Handles complex histories including multiple merge bases and rebased branches
Simple command-line interface that integrates with existing Git workflows
Outputs results in a format suitable for scripting and automation

Use Cases:

Auditing when bug fixes were merged from development branches to production
Verifying that feature branches were properly integrated into release branches
Generating reports for code review and compliance purposes
Debugging complex Git histories where commit origins are unclear

Alternatives:

git-log – git-log can trace ancestry but requires complex command-line options and doesn't directly answer 'which merge brought this commit here?'
git-merge-base – Finds common ancestors but doesn't identify the specific merge commits that integrated changes
