Highlights: This release continues to improve Redis compatibility and operational visibility. New command coverage includes CLIENT PAUSE/CLIENT UNPAUSE, CLIENT SETINFO, LATENCY, TDIGEST.TRIMMED_MEAN, BITPOS BYTE/BIT range units, conditional SET options (IFEQ, IFNE, IFDEQ, IFDNE), DUMP support for the SortedInt type, and CLUSTERX FLUSHSLOTS for clearing slot ranges in cluster mode.

This version also strengthens cluster and observability workflows by propagating slave failure state in CLUSTER NODES, exposing worker thread CPU time, adding more KMETADATA output, and introducing dictionary compression settings.

Stability and security were improved with Lua and LuaJIT hardening, safer replication/fullsync handling, stricter command permissions, RDB malformed intset validation, data race fixes, and multiple correctness fixes across Streams, Geo, TDigest, Set, ZSet, HyperLogLog, and scripting. Dependencies were also refreshed, including RocksDB v11.1.1, jsoncons v1.7.0, jemalloc v5.3.1, oneTBB v2023.0.0, zlib v2.3.3, and fast_float v8.2.7.

This release contains internal groundwork for Hash Field Expiration, but the HFE user-facing feature was disabled for the 2.16.0 release and should not be treated as available functionality in this version.
