Hi I've got 2 miners

1166 pro with 72 TH with firmware: 21071301\_4ec6bb0\_f6df907

1166 pro with 78 TH with firmware: 21042001\_4ec6bb0\_61407fa


Can anyone tell me how to understand their firmware dates/codes and check against their webpage to confirm if they are running the latest firmware. There is literally nothing on the internet about this.
The files listed make no sense on their webpage without the understanding of their file names.

Also from videos I’ve watch it suggest you need to use their software to do? Can’t it be done directly on the miner?

Thanks
