DragonFly 5.2.0 has been released. Spectre/Meltdown mitigations are in there, along with improvements for HAMMER2, accelerated video, and ipfw. My users@ post has the details on upgrading, as does the release notes.
A running description of activity related to DragonFly BSD.
Congrats guys! Always impressive to see a small team push regular releases. OpenBSD did beat you by a week with their Meltdown-safe release, but they “cheated” by releasing ahead of their announced date ;)
It took me a few minutes to install on a VPS. I’m now going to play with HAMMER2 a bit…
From the release announcement:
>>”We can now recommend H2 as the default root filesystem in non-clustered mode.”
That’s BIG news.
Yes, it’s impressive what a small group of motivated people with a *clear focus* can do!
Just one (maybe dumb) question: those of us who upgraded to 5.2 , in order to address the Meltdown/Spectre issue should also update the CPU microcode, right?
What is the standard way to do this? I thought about:
1) Installing sysutils/devcpu-data
2) Trying if it works with: service microcode_update onestart
3) If anything is ok, add /etc/rc.conf:
microcode_update_enable=”YES”
Is it right? Thanks!
Everything I know about microcode updates is here:

The concept is still new and strange to me.
Thank you! I’ll give it a try tomorrow.
But if it’s “new and strange” to you, I’ll probably brick my CPU :)
