Hotfix

An urgent fix applied to production to resolve a critical defect, usually outside the normal release cadence.

Definition

In GitFlow, hotfix branches are created from main and merged back into main and develop. In trunk-based development, the fix lands on trunk and is cherry-picked to the release branch if needed.

Example

A hotfix/1.4.1 branch fixes a crash and is tagged and deployed the same day.

Exam tip

Ensure the hotfix is merged back to the main development line so the bug does not reappear.
