Release Notes v2.0.5

Fluent Bit is a Fast and Lightweight Data Processor and Forwarder for Linux, BSD and OSX. We are proud to announce the availability of Fluent Bit v2.0.5.


Fluent Bit v2.0 is the start of the new stable series of the project. During the last months our primary focus has been around extending support for Metrics, Traces and improving performance, among many others.


Fluent Bit v2.0 is the stable release!, new changes on this version:

  • Core
    • engine: failed/expired retries is an error level event
    • chunk-trace: add a warning to enable tracing when it is not enabled.
    • multiline: do not permanently set ml group time to the first log time.
    • upstream: fix the stuck issue happened in Windows Server 2016 and 2019. (#6288)
    • input: fixed the argument verification code so it properly handles input plugins that establish outgoing connections.
    • build: windows: enable ECS filter (#6268)
    • build: Enable LTO for release builds (#6078)

  • Libs
    • monkey: upgrade to 4b081b3
    • cmetrics: update to v0.5.7


On every release, there are many people involved doing contributions on different areas like bug reporting, troubleshooting, documentation and coding, without these contributions from the community, the project won’t be the same and won’t be in the good shape that it is now. So THANK YOU! to everyone who takes part of this journey!
