Hi, Spring fans! Welcome to another installment of This Month in Spring! And what a month it's been! First things first: have you installed the just-released Java 22 yet? No? Well, get on it! It's out there and it's awesome! Java 22 brings with it Project Panama, more contemporaneously known as the foreign function interface. It's awesome! I look at it and a ton of the other new features in this blog, Hello, Java 22!
Second, I did a really long blog looking at building modern Spring applications in early 2024, check that out!
This last month has been nutty! I just had a lovely bit of PTO in Miami, Florida, where I got to see my ol' friend Jon Schneider, lead of OpenRewrite, a powerful tool for refactoring and migrating Java applications. And now, I'm in Bucharest, Romania, where I'll be keynoting the epic VOXXED DAYS Bucharest event here in a few short days. It's going to epic. Or, at least I hope so. Also, I'll be keynoting the Microsoft JDConf later this week. And, I'll be keynoting Google Cloud Next in early April! Don't miss any and all of these events! It'll be fun.
And, of course, the community has been as busy as ever in the last month since we spoke and there's a ton to get into, so let's delay not one second more, and let's dive right into it!
