## Build image policies for Workers Builds and Cloudflare Pages

[Workers](https://developers.cloudflare.com/workers/)

We've published build image policies for [Workers Builds](https://developers.cloudflare.com/workers/ci-cd/builds/build-image/#build-image-policy) and [Cloudflare Pages](https://developers.cloudflare.com/pages/configuration/build-image/#build-image-policy), which establish:

- **Minor version updates**: We typically update preinstalled software to the latest available minor version without notice. For tools that don't follow semantic versioning (e.g., Bun or Hugo), we provide 3 months’ notice.
- **Major version updates**: Before preinstalled software reaches end-of-life, we update to the next stable LTS version with 3 months’ notice.
- **Build image version deprecation (Pages only)**: We provide 6 months’ notice before deprecation. Projects on v1 or v2 will be automatically moved to v3 on their specified deprecation dates.

To prepare for updates, monitor the [Cloudflare Changelog ↗︎](https://developers.cloudflare.com/changelog/), dashboard notifications, and email. You can also [override default versions](https://developers.cloudflare.com/workers/ci-cd/builds/build-image/#overriding-default-versions) to maintain specific versions.
