config.py:181

• [nitpick] The function name '_setup_discord_log_channel_webhook' is now inconsistent with the setting key 'DISCORD_LOG_CHANNEL_WEBHOOK_URL'. Consider renaming the function to better reflect its purpose, such as '_configure_discord_logging_handler'.

It might be nice to reorder the _setup_discord_log_channel_webhook() classmethod above all the other setup classmethods as this suggests it should get called before the other setup methods (as it does correctly in the _setup_env_variables() classmethod).

Entirely optional to do this, so have approved anyways (and disabled auto-merge to allow you to decide).

Have merged because as far as i could tell it was already in the correct order? though some of the others aren't so if i can be bothered I'll fix the rest as it's own separate PR anyway

The call order is correct. I was referring to the definition order within the class. As in moving the _setup_discord_log_channel_webhook() definition to above the _setup_logging() definition.
