Today is the first day of Apple's Worldwide Developer's Conference (WWDC), and it gets started with a Keynote address from Apple. At 10 Pacific / 1 Eastern, Apple CEO Tim Cook and other executives will give a preview of software, and perhaps hardware, that Apple plans to release later this year. For example, I'm sure that Apple will debut iOS 15 and iPadOS 15, both of which should be final and ready to use this Fall.
