OTel Collector v0.159.0 released on 18-08-2026
OTel Collector v0.159.0 is out now. Operators and integrators should review bundled component updates and a notable eBPF profiler module bump that may affect profiling behaviour.
See the core and contrib changelogs on GitHub for component-level details: the core changelog is available at v0.159.0 core changelog and the contrib changelog at v0.159.0 contrib changelog.
What’s in this release
- Version bump to v0.159.0 and corresponding release metadata.
- Update of bundled OpenTelemetry Collector components — review core and contrib changelogs for receiver, exporter, processor and extension changes.
- Dependency update of module go.opentelemetry.io/ebpf-profiler to v0.0.202633, which may bring fixes or behaviour changes for eBPF-based profiling integrations.
Upgrade notes
- Review the core and contrib changelogs for any changes to receivers, exporters, processors or extensions that could affect configuration or behaviour; test configurations in a staging environment before rolling out.
- No functional runtime changes are expected from CI and Dockerfile updates, but CI and image builds may be affected — if you encounter build or workflow issues, revert to your previous Collector version until resolved.
Share any notes on your upgrade experience or unexpected behaviour so others can learn from the practical fallout and save an evening of debugging.
