Hi Spring fans! Welcome to another installment of This Week in Spring! I'm writing this from the oh-so-delightful (and delicious!) city of New Delhi, India. It's been a real privilege to come and visit so many amazing people. Last night my friend DaShaun and I presented here at the local Delhi JUG, too. Amazing. Tonight we're off to magnificent Mumbai!
It's been an insane week! First, you might remember that way back on May 11th, Spring manager Michael Minella posted that the normally scheduled May release train would be delayed, and on June 1st he detailed why: AI-driven CVEs. LOTS of CVEs. Read the posts for more. Suffice it to say, we doubled down and fixed the CVEs, and the new release train is finally here!
First things first: go upgrade to Spring Boot 4.1, now! Seriously, thank me later!
Now, on to the details!
