Hi, Spring fans, and welcome to another momentous installment of This Week in Spring! A lot to get into this week, but let's first take some time to address the meta: where are the May releases? If you read our May 11th post, you know they've been delayed. We wanted to speak a bit more about why in this important post titled Spring and Security in the Times of AI. Here's the TL;DR taken from the post directly (that is, I didn't even write the TL;DR, heh):

"TL;DR: As previously mentioned, the May Spring release train has been moved and condensed to June 8-14. The majority of projects within the Spring portfolio will require upgrades for newly released security patches. It is strongly recommended to upgrade as soon as possible to the latest patches. Details about the expected scheduling is available at calendar.spring.io."

But the article is very juicy and worth a read (and a share, please). It speaks to the rapid rise in CVEs: "March 2026 saw 55 new security reports submitted by the community that resulted in the 26 new CVEs being announced in April." And check out this insane image:

Please go check out the post. We're in a very different time and place than usual, and the Spring team is here to meet the moment for you, so that all you have to do is upgrade.

Alright, let's get into the blogs, tips, tricks, releases, and more that make up this week's roundup!
