Use it at work
Announcing it
- Code freeze starts Thursday at noon.
- After code freeze, only critical fixes go in.
Asking for an exception
- This is a P0 fix. Can we merge it during code freeze?

- Let's push the refactor until after code freeze.
Don't say this
Code freeze applies to the entire codebase or project, not individual functions. The phrase means stopping all changes, not freezing a specific piece of code.

Real examples(3)
- in a standup
"As of today, we're entering code freeze, so please finish all your pull requests by end of business."
- in a team meeting
"The code freeze will last until Thursday. Any critical bugs found during testing can be fixed, but no new features."
- in a chat message
"Code freeze starts tomorrow at 9 AM. Make sure your code is merged before then or it waits for the next release cycle."
More mistakes(2)
Handle with care. Do not confuse with 'feature freeze' (stopping new features) or 'release freeze' (general production lock). Code freeze specifically means no code changes are allowed.
- ✕Let us code freeze this bug quickly.✓Let's fix this bug quickly before the code freeze starts.
Code freeze is not an action you perform on a bug; it is a period when you stop making changes. You fix bugs during or before a freeze, not with it.
- ✕Code freeze means no one can work on the code.✓Code freeze means no one can commit new code changes, but testing and critical fixes continue.
During code freeze, developers still work (testing, documentation, critical fixes), but they cannot make non-critical code changes.

Questions(8)
- What happens during a code freeze?
- New features and refactors wait. The team tests the release candidate and only merges fixes for serious bugs, usually with extra approval.
- What is the difference between a code freeze and a feature freeze?
- A feature freeze comes first: no new features, but bug fixes and polish are fine. A code freeze is stricter: almost no changes at all. A change freeze, from ops teams, stops changes to production systems.
- How do you ask to merge something during a code freeze?
- Explain the risk and the impact: "I know we're in code freeze, but this fixes a crash on checkout. It's a one-line change with a test. Can I get an exception?"
- What does code freeze mean in software engineering?
- A code freeze is a period before a software release when no new code changes are allowed. Developers can only commit critical bug fixes. The goal is to stabilize the codebase and allow testing teams to work with a fixed version without new changes introducing bugs.
- How long does a code freeze usually last?
- Code freeze duration varies by company and project. In agile teams, it might last 1-3 days before each release. In traditional waterfall projects, it can last 1-4 weeks before a major release. The freeze typically ends when the product is released to production.
- Can I commit code during a code freeze?
- During code freeze, you cannot commit new features or non-critical changes. However, critical bug fixes that affect the release can be committed with proper approval from a senior developer or release manager. Most teams require a formal exception request.
- Is code freeze formal or informal?
- Code freeze is neutral in formality. It is standard terminology used in both casual team conversations and formal documentation. You will hear it equally in standup meetings, emails, and official release notes.
- What is the difference between code freeze and feature freeze?
- Feature freeze means no new features can be added, but code changes for optimization or refactoring might still be allowed. Code freeze is stricter—it stops almost all code changes. A project might have a feature freeze before entering code freeze.
