Fluent Bit versions 1.9 through 3.0 are EOL: https://fluentbit.io/announcements/older-versions/. This is a security risk. Do we have any options to upgrade besides building our own container?

By using the Fluent Bit v3.2, Fluent Bit Config can also be written in YAML notation instead of classic notation. This is the standard format for cloud native tools, and we would like to adopt this notation if possible.

As AWS for Fluent Bit, are there plans to upgrade Fluent Bit in the future?

I’m not very familiar with this, but is there a document summarizing why we use AWS for Fluent Bit instead of just Fluent Bit?

The Python dependencies and Fluent Bit version management don’t seem to be well-maintained.

I would also very much welcome a new fluent-bit version in aws-for-fluent-bit, as there are numerous adjustments and improvements in version 3.2.x, which I can unfortunately only look at longingly but not use. For example, attaching labels from kubernetes namespaces to the logs.

I feel like people have been requesting an update to FB 3.x for quite a long time now... doesn't seem to be a priority.

Hi all, I don't have exact dates to share at the moment but we are prioritizing finally updating aws-for-fluent-bit to an officially-supported and more recent fluent-bit upstream version this year (2025). Fluent-bit 4.0.0 has very recently been released, we're not sure yet if we will be jumping to 3.x or 4.x but it will be one of the two.

Finally, this would be a welcome update!
