Matthew Dillon has made a number of locking improvements, that speeds up performance on systems with multiple processor. Here’s his commit with some numbers. Note that he’s testing with these built-in utilities. This probably helps multiple cores too, and some attention is shown to Hammer, too.
If you are moving to the newest 1.8 version of Go, the language, you need to be on at least the last release of DragonFly 4.4, or 4.6. You’ve probably upgraded by now anyway, or at least I hope you have.
The 2.25 version was and still is installed by default. If you want to try out 2.27 instead, WORLD_BINUTILSVER=binutils227 is what you need. I didn’t test that, of course. The binutils changelog will tell you what’s different in 2.27.
UEFI, which I casually sum up as the replacement for BIOS, has been seeing some support in DragonFly, but not within the installer. Matthew Dillon and Sascha Wildner has ported over FreeBSD’s EFI ABI support, which I think means support for various EFI applications and features. I haven’t booted a machine using UEFI in any significant way, so I don’t have a good explanation – but I am sure this is useful for people with new hardware.
Update: some explanation plus a note that it’s experimental and you could brick your machine.
Imre Vadasz is working on full-offload scan support for wlan, imported from FreeBSD. That doesn’t change much from a user point of view, other that (I assume) reducing load and power usage a tiny amount. I’m reinforcing something most people don’t think about: there’s tiny computers inside your computer with their own firmware and processors, that you don’t directly control.
It’s now possible to put the /boot of your DragonFly system in the ‘a’ partition of a disklabel. It’s perhaps not major, but it’s another step in EFI support. EFI installs are possible now – if you do it manually.
