TL;DRRelease langfuse-rb 0.12.2 with the OTLP exporter metrics fix from #117.
WhyVersion 0.12.1 sends batch processor metrics to the configured reporter but omits OTLP exporter metrics. This patch release publishes the correction already merged into
main.The application continues to own its reporter. It flushes and closes the reporter after
Langfuse.shutdowndrains the tracing pipeline.ChecklistCloses AAI-466
VerificationThe complete repository check passed with 1,663 examples, 97.01% line coverage, and no RuboCop offenses. The release diff contains only the changelog, lockfile, and version file. Dependency versions are unchanged.
The 0.12.2 SDK exported a synthetic observation on shutdown. Independent Langfuse CLI readback verified its input, output, environment, and release. The documented adapter delivered batch processor and OTLP exporter metrics through a real DogStatsD client over localhost UDP. Langfuse did not flush, close, or shut down the application-owned reporter. Datadog backend ingestion was not tested.
The tag and gem build will use the verified merged release commit. RubyGems publication remains the manual MFA-protected step.
