Recently I explained to a student that Arc Pro is kind of like the Disney of GIS software. It’s powerful and colorful and very well known, but if you try and do things it doesn’t like, you’re going to have a bad time.

QGIS is my daily driver. It’s so much lighter and so much less bloat, it’s just wildly more efficient. These days I pretty much use Arc for machine learning features.

That page is also down.

Even previous ones, listed on Google when searching "QGIS changelog" are all down. So it's a server error on their side most likely.
