Look Into the iOS 15 Jailbreak
Developers have finally released a tool that's compatible with iOS 15, but it only works with select iPhone models.
The new palera1n jailbreak is based on checkm8 and it works with all versions of iOS between iOS 15.0 and iOS 16.2. Currently, it only works with iPhone 8, iPhone 8 Plus, and iPhone X.
There aren't a ton of tweaks available yet and there are some caveats, but at least a jailbreak option is now available to those who still love to jailbreak.
If you're thinking about jailbreaking your phone on iOS, you'll want to weigh the pros and cons before you take the plunge.
