# WIP thingy that downloads official patch notes, starting from 24/12/2025 going one week back at a time
# WIP because patch notes don't always come out on thursdays, which this script just assumes
# the "idea" is to download a ton of patch notes and get the corresponding recent news articles from the wiki
# and train or fine tune some kind of model to do patch notes better
