 ## Change Log
 
+#### v39.5(2021-09-24)
+
+- `feature`: `ergo` new LHR mode for mining ERGO, enable it by manually adding `-lhr` option
+  - Same as LHR mode in `ethash`, `-lhr` value represents expected hashrate to reach `value` percent of non-LHR GPU's hashrate, supports comma-seperated list to indicate `-lhr` value for each GPU, and `-lhr -1` to disable.
+  - For GPUs with Hynix GDDR6 memory, LHR mode is not recommended for the poor performance.
+  - For GPUs with non-Hynix GDDR6 memory, e.g. 3060 3060ti 3070, start trying with `-lhr 85`
+  - For GPUs with GDDR6X memory, e.g. 3070ti 3080 3080ti, start trying with `-lhr 100`
+  - When mining lock is detected during ERGO mining, miner will automatically decrease `-lhr` value by 0.5, and continue mining. max decrease times is 10, which sums to 5.0
+- `optimize`: `ergo` Lower power consumption on Nvidia GPUs.
+
 #### v39.4(2021-09-21)
 
 - `fix`: `octopus` Fix error hash issue.

 ## 修改记录
 
+#### v39.5(2021-09-24)
+
+- `功能`: `ergo` 新增LHR模式，需手动添加 `-lhr` 参数启用
+  - 与`ethash`的LHR模式相同，`-lhr`值表示期望达到的非LHR卡算力的百分比，支持列表传入每张卡不同的参数，传入 -1 禁用
+  - 对于海力士显存颗粒GDDR6的LHR显卡，不推荐使用 `-lhr` 模式，效果不明显
+  - 对于其他 LHR 版本GDDR6显卡，即 3060 3060ti 3070，推荐 `-lhr 85` 开始尝试
+  - 对于 LHR 版本GDDR6X显卡，即 3070ti 3080 3080ti，推荐 `-lhr 100` 开始尝试
+  - 当ERGO挖矿中检测到LHR锁以后，miner将尝试恢复并自动将 `-lhr`值降低 0.5 继续挖矿，最多降低10次
+- `优化`: `ergo` 降低N卡挖矿功耗
+
 #### v39.4(2021-09-21)
 
 - `修复`: `octopus` 修复错误提交的问题
