Script now supports a FIPS-safe execution mode that avoids client-side SHA-1 computation, which is blocked in strict FIPS environments. A new NewScriptServerSHA constructor uses SCRIPT LOAD to obtain and cache the digest from the server, then runs commands via EVALSHA/EVALSHA_RO. Falls back to EVAL/EVALRO if loading fails, and transparently retries once on NOSCRIPT. The default behavior is unchanged for existing users.

Added a new step-based FT.AGGREGATE pipeline API via FTAggregateOptions.Steps, allowing LOAD, APPLY, GROUPBY, and SORTBY (with per-step MAX) to be repeated and interleaved in arbitrary order — matching Redis's native multi-stage aggregation semantics. The legacy Load/Apply/GroupBy/SortBy/SortByMax fields are now deprecated.
Added DoRaw and DoRawWriteTo methods for executing arbitrary commands and reading the raw RESP response. Useful for proxying, custom protocol inspection, and working with commands not yet wrapped by go-redis.

Added DialerRetryBackoff option (plumbed through Options, ClusterOptions, RingOptions, FailoverOptions) to let callers customize the delay between failed dial attempts. Helpers DialRetryBackoffConstant and DialRetryBackoffExponential (with jitter and cap) are provided out of the box. Dial timeout is now also applied per attempt rather than across all retries.
