Question: Why is Fluentd 1.17.1 the latest supported version (latest fluentd available: 1.19.x)?

Is your feature request related to a problem? Please describe.

Hi team,

I noticed that the current Fluent Operator Helm chart (and the CRD defaults) still reference Fluentd version 1.17.1 as the supported or default image.

Is there a specific reason why newer Fluentd versions (1.18.x or 1.19.x) are not yet supported or tested?
For example, are there known compatibility issues, API changes, or planned updates to add support for the latest Fluentd releases?

Describe the solution you'd like

Container images for up-to-date fluentd versions (e.g. 1.19.0) are available.

Additional context

I’d like to understand if it’s safe to upgrade manually to a newer version, or if there are breaking changes that the operator needs to address first.

Thanks in advance for clarifying!

We likely just need to test and release a newer version of fluentd. I'll try to take a look at it this week unless someone beats me to it.

We build our own fluentd images which adds some additional functionality for hot reloading the configuration.
