What shipped
- v5.5.1 released with fixes for PromQL range functions returning empty results and query_range end parameter rounding. Release
- Fixed rate(), irate(), increase(), delta(), deriv(), and related functions that returned no series when step >= range [1]. Pull request #981
- Fixed query_range end parameter to floor to the 15s grid instead of ceiling, preventing over-extended query ranges [2]. Pull request #979
- Documented ClickHouse table ordering and ADVANCED_SAMPLES_ORDERING configuration with defaults and behavior [3]. Pull request #982
- v5.5.0 released with compression codecs for samples, traces, profiles tables and optional metrics_15s aggregation. Release
- Added METRICS_15S_ENABLED flag to opt metrics out of the metrics_15s aggregate table, reducing disk cost at 15s scrape resolution [7]. Pull request #978
- Added compression codecs to samples, traces, and profiles tables, achieving 37% disk reduction on samples_v3 [8]. Pull request #977
- Fixed Elastic ingest to properly index _index and _id labels instead of storing empty values [6]. Pull request #975
- SmartBuffer now grows its RAM chunk on demand instead of preallocating 5MB for all reader endpoints [5]. Pull request #960
Why it matters
These releases fix critical issues with PromQL range functions and query parameter handling that affected correctness of results. Storage efficiency improvements through compression and optional aggregation tables help reduce infrastructure costs. The fixes make the system more reliable for both metric and log workloads.

Gigapipe v5.5.1: fixed PromQL range functions returning empty results, corrected query_range end rounding, and documented ClickHouse table ordering. v5.5.0 added compression codecs (37% smaller samples) and optional metrics_15s aggregation.
Gigapipe v5.5.1 and v5.5.0 ship critical fixes and improvements: PromQL range functions now return correct results, query_range end parameter rounds correctly, and compression codecs reduce disk usage by 37% on samples tables. New METRICS_15S_ENABLED flag lets operators opt out of expensive aggregation at 15s scrape resolution. Elastic ingest now properly indexes _index and _id labels.
