Upgrade Notes

1. Logs & access logs syntax: The chart now aligns its logging keys with the upstream Traefik syntax with PR #1887.
   • logs.general is renamed to log (e.g. logs.general.level → log.level).
   • logs.access is renamed to accessLog (e.g. logs.access.format → accessLog.format).
   • Filter and field keys are now camelCased: filters.statuscodes → filters.statusCodes, filters.retryattempts → filters.retryAttempts, filters.minduration → filters.minDuration, and fields.*.defaultmode → fields.*.defaultMode.
   • The accessLog.fields.general nesting level is removed: fields.general.defaultmode → fields.defaultMode.Expand commentComment on line R27Resolved
2. File provider content: providers.file.content is now an object ({}) instead of a string ("").

Tip

Image registry and repository now default to null.
The chart now automatically resolves the full official image URI for both Traefik Proxy and Traefik Hub.
