• NEW parameters for commandline.py:-
  • -sd, --seed: Set a custom seed to be used by random, for generating similar images across runs
• Cleanup the codebase using fstrings
• Add FULL typing support for providing a better experience to library users

Version checking

• Improve version checking efficiency

  The version is only checked once every few days and saved into a local file. This file is checked afterwards. Eliminates the need to send request to pypi

• Add --version argument to the commandline script

Add support for floats as increment/decrement

• Add support for floats as Increment/Decrement (glitch_change)

  You can now use a value between +-0.0 and +-10.0 (inclusive)

• Glitching intensity can now be in range 0.1 to 10.0 (inclusive)

Patch - Fix help text formatting in `commandline.py`
