Gábor Hojtsy: Introducing the Drupal 9 deprecation status tool on

You’ve probably seen the stats Dries Buytaert cites in his State of Drupal keynotes, and some of my earlier blog posts where I call for deprecated API removal automation and fixing drupal_set_message() calls all around in particular. You might have been wondering where is all that data coming from and how can you get a better sense of where Drupal projects stand and how can you help make progress. Well, I had a lot of fun recently building a new tool (with help from Matthew Grasmick, Shannon Vettes and Angie Byron) for that does exactly that! Check out this demo and head over to to try it out.
