- Major LogQL enhancements: parse logs for labels, filter on extracted labels, format output, graph logs as metrics, and generate Prometheus‑style alerts directly from logs.
- Boltdb shipper is now production‑ready, removing the need for external stores; includes a potentially breaking schema change and removal of the deprecated Promtail entry‑parser config (use pipeline stages).
- Added a "verify config" flag to validate Loki configuration at startup and exit with status 0 on success.
