@@ -60,6 +60,8 @@ We have cleaned up some commands in the `lotus-worker` to make it less confusing
 The `lotus-miner sector list` is now running in parallel - which should speed up the process from anywhere between 2x-10x+. You can tune it additionally with the `check-parallelism` option in the command. The `Lotus-Miner info` command also has a large speed improvement, as calls to the lotus legacy market has been removed.
