Redis 2.8版本标准架构不支持 bitfield，Redis 4.0、5.0、6.2版本都支持。
Redis 4.0、5.0均不支持 bitfield_ro、getdel、stralgo 命令。
6.2、7.0，及其 ValKey 8.0版本支持 bitfield_ro、getdel、stralgo、getex。
集群架构跨 Slot 场景，支持 mget、mset 命令，不支持 bitop、msetnx 命令。
Redis 7.0版本，及其 ValKey 8.0支持 lcs 命令，具体更新如下所示。
命令族 | 命令 | 新增说明 |
string 族 | SET key value [NX | XX] [GET] [EX seconds | PX milliseconds | EXAT unix-time-seconds | PXAT unix-time-milliseconds | KEEPTTL] | 新增 NX 和 GET 参数。 NX：表示 Not exists，只有当键不存在时，才会设置键值对。 GET： 设置新值，返回旧值。 |
| BITPOS key bit [start [end [BYTE | BIT]]] | 新增 BYTE 和 BIT 参数。指定偏移量的单位。BYTE：表示字节偏移，BIT：表示位偏移。默认为 BYTE。 |
| LCS key1 key2 [LEN] [IDX] [MINMATCHLEN min-match-len] [WITHMATCHLEN] | 新增命令。 返回两个 key 的最长公共子序列。 |
