If you'd like to run the latest beta version of FileBot (4.9.0 as of 1/30/2020) and you've purchased a license, you can install it using the instructions below:
mkdir filebot-beta-portable && cd filebot-beta-portable
sh -xu <<< "$(curl -fsSL https://gist.githubusercontent.com/tylerforesthauser/123ad1d1dc9433664cb7c6d5718d1225/raw/b0b19388be1b447cd24048fce2a905d8df923bef/filebot-beta-installer.sh)"
filebot --license /path/to/FileBot_License_P1234567.psm
Nothing more needs to be done. If you're using FileBot for your torrent client post-processing, that will now use this version of FileBot as well. Enjoy!
Note: You will very likely need to update Java for this version of FileBot. Download and unarchive OpenJDK 11:
