Thread.isAlive was renamed to Thread.is_alive in python 3.9

[PiRK]

This causes an error when a transaction is received or sent with the development version (run from source) of Electron Cash or Electrum ABC (released versions currently ship with python 3.8, so for now it should still work).

Traceback
Traceback (most recent call last):

Thanks for letting me know! I'm guessing I should probably use .is_alive() instead, but I'll need to learn how to run the dev version (never done it). Their might be a new attribute. I'll try figure it out tomorrow. For now I'm spelling out all the OpCodes in mixed case, so that it auto-decodes either using OpCodes or OP_CODES (another QCheckBox toggle). e.g. OP_OUTPOINTTXHASH vs OutpointTXHash.

Luckily, running from sources is relatively easy if you are familiar with terminals.

Installing the mandatory dependencies is basically these 3 commands:

git clone https://github.com/Electron-Cash/Electron-Cash; cd Electron-Cash
pip install -r contrib/requirements/requirements.txt --user
pip install pyqt5

And then, run with ./electron-cash, or python3 ./electron-cash

Electron Cash's README has additional instructions, if you want the optional dependencies: https://github.com/Electron-Cash/Electron-Cash/blob/master/README.rst

Thanks for the useful plugin!

I've released v1.0.4 which should resolve this issue. However I should still check for myself. Thanks again!
