See the GitHub release page (https://github.com/grafana/loki/compare/v3.7.4…v3.7.5) for full details and the packaged artifacts.
What’s in this release
- Packaging and release workflow: restores building of deb and rpm packages and disables Docker plugin publishing on the release-3.7.x branch so packaged artifacts are produced for the patch release.
- Ingester flush race fix: resolves a race in the ingester flush logic on release-3.7.x to prevent concurrent flush-related errors.
- Security dependency updates: multiple modules updated, including github.com/klauspost/compress to v1.18.7, go.opentelemetry.io/otel to v1.42.0, golang.org/x/text to v0.39.0 and google.golang.org/grpc to v1.82.1.
