DragonFly 5.4.1 is out, just in time for Christmas. My users@ post describes upgrading, as do the 5.4 release notes. The changes in this version are in the tag commit, which can be summed up as “keyboard fix, dhcpcd support, HAMMER2 improvement”.
Images are available for download at various mirrors, too. If you’ve recently upgraded to 5.4, it’s the normal build process.
