Breaking changes

What to check before upgrading, taken from the notes of the last 30 releases.

  • v5.0.3Sep 23, 2026

    Vault Error Breaking the Mailer

    Fixed error that was interrupting the mailer service on startup.

  • v5.0.0May 26, 2026

    Breaking Changes & Deprecation

    • Reverse URL is now compulsory when running Cells behind a reverse proxy. The external URL must be configured explicitly — relying on implicit detection from incoming requests is no longer supported.
    • Bundled Helm subcharts are deprecated. Production deployments must point Cells at external (managed or operator-deployed) services. Bundled charts remain only for local trials.
    • GCS datasources removed, and structured datasources are now hidden behind an advanced configuration.
    • Legacy config migrations deprecated — upgrades go through the new v4 → v5 migration framework (schemas, personal access tokens, policies, namespaces, metadata). Read the upgrade guide before you begin.
    • Misc API changes: editor URL keys exposed on REST endpoints, presigned-URL flag on /versions, expanded CheckFileInfo response in the WOPI/Collabora integration, and several smaller adjustments — see the API changelog.
