Status

Pending upstream fix

Impact

Upgrading github.com/prometheus/prometheus from v0.307.3 to v0.311.3 (the only fixed version) breaks Grafana Tempo 2.10.5: prometheus removed the github.com/prometheus/prometheus/tsdb/errors package, which github.com/grafana/tempo/modules/generator/storage imports directly. Awaiting an upstream Tempo release compatible with prometheus v0.311.3+.
