Hotfix
A hotfix is a software update or patch applied to a production system to fix a critical bug or security vulnerability without requiring a full release cycle. It is deployed urgently to address issues that could cause significant operational disruption, data loss, or security breaches. Hotfixes are typically small, targeted changes that bypass normal testing and deployment processes to minimize downtime.
Developers should use hotfixes when immediate action is needed to resolve severe problems in live environments, such as security exploits, system crashes, or data corruption. This approach is essential in industries like finance, healthcare, or e-commerce where downtime can lead to substantial financial or safety risks. However, hotfixes should be followed by thorough testing and integration into the main codebase to prevent technical debt.
