The fourth stop on our North America JUG Tour 2023 was Omaha and Omaha Java User Group. By now, we’re starting to get the hang of it. Gerrit started off with his talk about vulnerabilities in Java and the build chain in general. An important topic that just becomes more and more relevant.

I did the migration talk about how to get from Spring Boot 2 to Spring Boot 3 with a focus on Jakarta EE in that context. The demo with preview features from Java 21 that I introduced yesterday is now a part of the presentation. Check out the slides at my SpeakerDeck.

This meetup closed the US leg of the tour as we will go across the border to Canada tomorrow. We will have a pretty tight connection at O’Hare, but hopefully, we will make it to Montreal in time for the meetup there.
