What is a hotfix?

A hotfix refers specifically to a quick patch or update that is released to resolve a particular issue or bug in software, typically without requiring a complete upgrade of the software system. This swift intervention allows developers to address critical problems that may affect users or operations immediately, ensuring the software continues to function effectively.

In contrast, options describing a comprehensive software upgrade, a planned maintenance activity, or a lengthy installation process do not accurately reflect the nature of a hotfix. Comprehensive upgrades involve a more extensive set of changes and improvements, while planned maintenance refers to regularly scheduled updates or system checks that may or may not address particular emergencies. Installation processes, especially those described as lengthy, generally pertain to setting up new software rather than making quick corrections to existing software. Thus, the distinction lies in the immediacy and focus of a hotfix on solving urgent software issues.
