 ## Change Log
 
-#### v42.1(2022-05-24)
-
-- `fix`: `ethash` Linux LHR unlocker can not unlock on certain GPUs.
+#### v42.2(2022-05-26)
 
-#### v42.0(2022-05-23)
+**Compared to v41.5**
 
-- `feature`: `ethash` Extend LHR unlocker work with old driver versions. All previous drivers should work until `515.x`.
-- `fix`: `ethash` Improve LHR unlocker stability under Linux.
+- `feature`: `ethash` Add a new option `--lhr-mode` to select LHR unlock mode.
+  - `--lhr-mode 1` is the default mode and is the same as which in `v41.5`
+  - Try to use `--lhr-mode 2` if stability issue encountered in `mode 1`, for json config, use `"lhr-mode": "2"`
+  - `LHR v3` GPUs can only use `mode 1`
+- `feature`: `ethash` Extend LHR unlocker to work with old driver versions. Starting from `Windows v512.95` and `Linux v515.x`, LHR unlocker no longer works, make sure not to use these new driver versions.
 - `optimize`: `ethash` small hashrate improvement on Nvidia GPUs.
 - `feature`: Add `GDDR6X` memory temp in summary table for Linux.
 - `feature`: Add `GPU RAM type` and `GPU RAM vendor` in log.
 - `feature`: Add Nvidia driver versoin in summary table.
+- `feature`: `ethash` Add `eth_submitHashrate` for `nicehash (EthereumStratum)` protocol.
 - `feature`: If `Overclock` applies through `nbminer`, reset settings to stock when miner exit.
 - `feature`: `-mt` option on windows does not require custom driver anymore (admin priviledge is required).
 - **`NOTE`: NBMiner versions older than v39.5 (not included) will run into issue when ETH reaches `EPOCH 520` (Approx mid September). Please make sure to upgrade to a newer version before that if ETH is still with POW.**
