Loki v3.7.0 released on 26-03-2026
Loki v3.7.0 is out now. Operators running distributed Loki should review scheduler, worker and parsing behaviour as the release includes several breaking changes that affect scheduling decisions, concurrency and label precedence.
See the project’s GitHub release notes for full details, configuration pointers and upgrade instructions.
What’s in this release
- Engine scheduler is now aware of total compute capacity, which alters scheduling decisions and resource accounting.
- Worker threads are shared across all scheduler connections, changing concurrency and worker allocation behaviour.
- Parsed labels no longer override structured metadata, affecting existing parsing and relabelling workflows.
Upgrade notes
- These are breaking changes — review scheduler capacity settings, worker allocation and parsing/relabel pipelines in a staging environment before upgrading; consult the GitHub release notes for exact guidance.
- If the new behaviour causes problems in production, revert to your previously deployed version until you have tested configuration changes and validated behaviour.
Share comments on your upgrade experience or any unexpected behaviour on the project’s GitHub so maintainers and other users can follow up.
