versions 29 and older patching question

[DANYBOYUSA-2]

Are versions 29 and older maintained?

Short answer: Jest 29 and older are not actively maintained. Only the latest major version (currently 30) receives bug fixes and new features.

Jest follows a policy where only the latest major version gets regular patches. If you're on 29.x, you won't get security patches or bug fixes unless something critical comes up (and even then, it's not guaranteed).

If you're stuck on 29 because of a dependency or breaking change in 30, the recommended path is:

1. Check the Jest 30 migration guide for breaking changes
2. The most common blockers are the new module resolution defaults and changes to timer mocking
3. If a specific package in your stack doesn't support Jest 30 yet, file an issue on that package rather than waiting for a Jest 29 patch

For security-sensitive projects, staying on an unmaintained major version is a risk worth addressing sooner rather than later.
