Any hopes of getting this fixed anytime soon? 🤞

Would like to have an ETA for that. v2beta2 is being removed on GKE by 30th March (previous date was 29th Feb). We've started using this chart recently and shouldn't be that bad to move to another one, but prefer not to do.

Just in case helps, I've duplicated this as #463 for fixing conflicts

When will it merge?
EKS 1.29 cant use helm on fluentd since the deprecation.

There's no definition that you only generic functions are part of the _helpers.
IMO it's just needing to change files if you want to see what it is and keeping things contained as you would do with normal code.

@ALL Anything else you would find has priority to be fixed/added?

#424 prevents us from any easy update
