- Significant performance improvements: faster binary ops, regex fork, new S3/filesystem schema, and hedged storage requests.
- Promtail adds new ingestion sources (Docker daemon, Cloudflare, GELF) and supports global and pipeline rate limiting.
- Breaking config change: split queries by interval moved to limits config with new default (30m), may prevent Loki from starting; numerous bug fixes across query handling, Azure blob, live tailing, and retention.
