Re: FreeBSD 15.0-ALPHA3 Now Available

My experience may be useful:
I used pkg to upgrade from ALPHA2 to ALPHA3.

First i only successfully upgraded the kernel:
pkg install FreeBSD-kernel-generic
reboot

then:
pkg-static upgrade

failed with:

A second pkg-static upgrade successfully finish with some warnings:
