I saw the update just now on his twitter.
Users can now deposit up to 0.05 BTC and withdraw for as little as 0.000002 BTC in fees.
I asked why deposits in the lightning network are restricted unlike other networks?
It might be because there presently is not much liquidity in the Lightning network to send more than 0.05 BTC and expect them to be recieved successfully 100% all of the time. I reckon it can handle a higher amount per transaction, however, Binance might be starting it more cautiously then slowly increase the limit over time.
