Code Freeze
ELI5 — The Vibe Check
A code freeze is when the team stops adding new features and only allows bug fixes — like telling the kitchen to stop taking new orders and finish what's on the stove. It usually happens before a big release. 'No new code goes in until we ship.' It sounds simple until someone says 'just one tiny feature' and the freeze melts faster than ice cream in July.
Real Talk
A code freeze is a period during the release cycle where no new features are merged into the release branch, only critical bug fixes. It stabilizes the codebase for testing and deployment. Code freezes are common before major releases, during holiday periods, and ahead of compliance audits. Feature flags can reduce the need for code freezes by decoupling deployment from release.
