# Version equivalents between Core Agent and Fluent Bit

<Note>
  This feature isn't available to all Chronosphere Telemetry Pipeline users.
  For more information, contact [Chronosphere Support](/support).
</Note>

In Chronosphere Telemetry Pipeline, you can use [fleets](/ingest/pipeline/v2/fleets) to manage instances
of Fluent Bit and Core Agent. Core Agent is based on Fluent Bit, but Core Agent
updates on its own cadence and uses a separate versioning system, which means
the version numbers between the tools aren't identical.

Use the information in this page if you need to reference the
[Fluent Bit documentation](https://docs.fluentbit.io/manual) for equivalent
features in Core Agent.

<Note>
  Core Agent is distinct from the agent that powers standard telemetry pipelines.

  For information about pipeline agent versions, see
  [Telemetry Pipeline component versions](/ingest/pipeline/v2/component-versions).
</Note>

The following table lists each version of Core Agent and its corresponding version
of Fluent Bit:
