Hi Spring fans! Happy New Year! And welcome to another installment of This Year in Spring!

I write this edition from a desk overlooking the beautiful jungle of Martinique, a beautiful island nation in the French Caribbean. I’m sipping some rhum martinique, enjoying the semi-sweltering heat, and thinking about the year that's been 2024.

Hi, Spring fans! (and happy holidays!) in this installment I talk to Intact's Luke Shannon about their use of Spring, developer portals, and so much more.

We are happy to announce the 1.0.0 Milestone 5 release of Spring AI

While we have tried to make this transition smooth, by deprecating methods and classes for one release cycle, there are some breaking changes we know about and perhaps some that we don’t, so please bear with us. See the section on Breaking Changes below.
