Hi, Spring fans! Welcome to another installment of This Week in Spring! It's a wonderful tuesday here in my home town of San Francisco as I write this from my condo's balcony, fresh off more than three weeks on the road.

By the time we'll speak again in a week, Halloween will have come and gone. Are you all ready for Halloween? What're you gonna dress as? I always go as PHP code. The horror!

The excitement is building for Spring Boot 4 and Spring Framework 7, both of which are scheduled to be released in November of 2025. So fun! There's a ton of good stuff to look at this week, so let's dive into it!
