v1.0.4

v1.0.4 — 2026-06-22

Highlights

Smart Router v1.0.4 introduces critical breaking changes to observability and configuration, requiring operators to update dashboards, alerts, and startup scripts before upgrading. All Prometheus metrics have been stripped of the legacy lava prefix, meaning any monitoring infrastructure referencing lava_rpc* or the specific lava_errors_total counter must be migrated to the new smartrouter_* and rpc_* namespaces, with errors now tracked under smartrouter_errors_total. Additionally, the default OpenTelemetry service.name has been changed from lava-rpcsmartrouter to smartrouter, which will break existing trace filtering and aggregation if not adjusted in collector configurations. Finally, the CLI flags used to tune upstream routing weights have been renamed; operators must replace all instances of provider-optimizer-* weight flags with their new qos-* equivalents to prevent unrecognized flag errors during startup.

Changes

⚠ Breaking changes

• refactor!: drop the lava prefix from smart-router metric names (#138) 4e21206
  • All Prometheus metric names emitted by the smart router are renamed. Any dashboard, alerting rule, recording rule, or scrape relabeling that references the old lava_rpc* names must be updated to the new smartrouter_* / rpc_* names. The default OTel service.name also changes from "lava-rpcsmartrouter" to "smartrouter".
• refactor!: rename lava_errors_total -> smartrouter_errors_total (#138) bce3a24
  • The lava_errors_total Prometheus counter is renamed to smartrouter_errors_total. Dashboards/alerts referencing the old name must be updated.
• refactor(flags)!: rename provider-optimizer-* weight flags to qos-* (#137) abe524c
