Stream Broken with Alpaca-Trade-API version 0.48 / api version 0.46 working

If I use alpaca-trade-api version 0.46, the simpleStream.py example demo works:

pip3 install alpaca_trade_api==0.46

python simpleStream.py --all (under alpaca-trade-api-python/examples directory from github repository)

Example Output (seems OK):

Here is broken output using api version 0.48:

( pip3 install alpaca_trade_api==0.48 )

unknown channel A.* (you may need to specify the right data_stream)

Hi. Did you figure it out?
