 # CHANGELOG - redis
 
+## v1.5.7 (2026-06-21)
+- **兼容性增强**: 对已废弃的 Redis 命令增加新协议兼容支持。
+  - `SETEX` → `SET key val EX sec`，`SETNX` → `SET key val NX`，`HMSET` → `HSET`，`GETSET` → `SET key val GET`，`ZREVRANGE` → `ZRANGE ... REV`。
+  - 新增 `compatFlags` 降级标记位，默认尝试新协议；当新协议报错时自动回退旧协议并记录标记，后续直接使用旧协议。
+- **依赖更新**: 升级 `shell` 至 `v1.5.4`。
+
 ## v1.5.6 (2026-06-21)
 - **JS 对齐**: 重构 JS 导出为具名函数，并引入 `jsmod.MakeError` 动态包装错误以获取调用栈。
 - **依赖更新**: 升级依赖 `jsmod` 至 `v1.5.3`，`cast` 至 `v1.5.3`，`rand` 至 `v1.5.3`，`encoding` 至 `v1.5.4`，`shell` 至 `v1.5.3`，`safe` 至 `v1.5.2`，`id` 至 `v1.5.4`，`crypto` 至 `v1.5.3`，`file` 至 `v1.5.5`，`config` 至 `v1.5.3`，`log` 至 `v1.5.8`。
