That title sounds like clickbait, but I'm 110% convinced that it's true.  

Even in just the last 7 days, we've seen major changes.

In the Drupal world, Dries Buytaert reversed a fundamental Drupal principle. For 15 years, each new Drupal version has involved massive changes. No longer. Each version will now be backwards compatible. I'm often wrong, but I'm going to claim this one as an accurate prediction. This is absolutely the correct decision: huge, breaking updates are as out-of-date as punchcards in 2017.
