This Week in Spring - July 14th, 2026

In two short months, on this date in September, Java 27 will be here! Who's excited? I'm excited!

I'm in delightful Denver, CO, for the amazing UberConf. I just delivered a workshop that was scheduled from 09:00 to 17:00, but it went into overtime, and we just concluded at 18:30. Long day (story of my life)! Such a nice way to spend the day, though. Surrounded by cool people. As usual, though, the Spring ecosystem waits for no one. Let's dive right into this amazing week in Spring!
