Upgrade urgency HIGH: There are critical bugs that may affect a subset of users.

Bug fixes

• Avoid memory leak of new argv when HEXPIRE commands target only non-exiting fields (#2973)
• Fix HINCRBY and HINCRBYFLOAT to update volatile key tracking (#2974)
• Avoid empty hash object when HSETEX added no fields (#2998)
• Fix case-sensitive check for the FNX and FXX arguments in HSETEX (#3000)
• Prevent assertion in active expiration job after a hash with volatile fields is overwritten (#3003, [#3007])
• Fix HRANDFIELD to return null response when no field could be found (#3022)
• Fix HEXPIRE to not delete items when validation rules fail and expiration is in the past (#3023, [#3048])
• Fix how hash is handling overriding of expired fields overwrite (#3060)
• HSETEX - Always issue keyspace notifications after validation (#3001)
• Make zero a valid TTL for hash fields during import mode and data loading (#3006)
• Trigger prepareCommand on argc change in module command filters (#2945)
• Restrict TTL from being negative and avoid crash in import-mode (#2944)
• Fix chained replica crash when doing dual channel replication (#2983)
• Skip slot cache optimization for AOF client to prevent key duplication and data corruption (#3004)
• Fix used_memory_dataset underflow due to miscalculated used_memory_overhead (#3005)
• Avoid duplicate calculations of network-bytes-out in slot stats with copy-avoidance (#3046)
• Fix XREAD returning error on empty stream with + ID (#2742)

Performance/Efficiency Improvements

• Track reply bytes in I/O threads if commandlog-reply-larger-than is -1 (#3086, [#3126]). This makes it possible to mitigate a performance regression in 9.0.1 caused by the bug fix [#2652].
