We’ve published build image policies for Workers Builds and Cloudflare Pages, 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, dashboard notifications, and email. You can also override default versions to maintain specific versions.
