Feature-complete v2.44.0 (lib/churl, lib/col, BFloat16, QBit, scanTypeDuration, Options.Logger *slog.Logger) — fixes the [email protected].0 downgrade RED caught. Package datastore, module github.com/hanzo-ds/go, depends only on hanzo-ds/native. Wire strings preserved VERBATIM (X-ClickHouse-* headers, sql.Register("clickhouse"), clickhouse:// DSN, ClientName="clickhouse-go") — consistent with native.
