Outdated information in "1.2.1. What Can FreeBSD Do?" https://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/nutshell.html We have new features like SMP, Memory protection, and even Preemptive multitasking! We should likely add things like zfs, vmnet, or whatnot.
I think we can close this. OpenZFS is listed there among other things. Listing all the features FreeBSD has would be too exhausting for the reader and it's doubtful that such a long list is actually desirable in the chapter. It's enough to wet people's appetite, they can find details in the individual handbook chapters.
