Hotfix

ELI5 — The Vibe Check

A hotfix is an emergency patch you ship immediately to fix a critical bug in production — no waiting for the next planned release. It is the coding equivalent of patching a hole in a ship while sailing. The name says it all: it is hot because it is urgent and live.

Real Talk

A hotfix is an unplanned patch deployed directly to production to address a critical defect, security vulnerability, or outage. Unlike regular releases, hotfixes bypass the normal development cycle (sprint planning, feature branch, staging) to minimize downtime. In Git, hotfixes are typically branched from the production tag, fixed, and merged back to both main and the current development branch.

# Hotfix workflow:
git checkout main
git checkout -b hotfix/payment-crash

# Fix the critical bug...
git add .
git commit -m "fix: prevent crash when payment amount is zero"

# Merge to main AND develop:
git checkout main && git merge hotfix/payment-crash
git checkout develop && git merge hotfix/payment-crash
git tag -a v1.2.1 -m "hotfix: payment crash"
