v2.3.21
Fixed
- Cluster overlay charts rendered empty (500 error). The per-group series query bound
the time-bucket width as a text parameter (time_bucket(text, …) does not exist) instead
of inlining the allowlisted constant, so CPU/memory charts on the Cluster page failed.
Inlined it, matching the single-series query. Regression-guarded in
scripts/check-kube-stats.sh.
