GCC has been updated by John Marino from 5.3 to 5.4 in DragonFly – the 5.4 closed bug list on the GCC site is a good way to find out the benefits.

There’s been multiple reports of pulseaudio causing problems for DragonFly users. It would get pulled in as a dependency, and audio would suddenly stop working. Uninstall, and audio is fine. John Marino has removed it from dports, to prevent that exact problem.
There’s been a number of commits lately around higher optimization levels for your DragonFly kernel. It looks you can even set it systemwide. Boot code remains at -O; any higher level will make it explode. Is this safe? I have no idea!
If you are on DragonFly-current, AKA DragonFly 4.7, make sure to perform a full buildworld on your next upgrade. Tomohiro Kusumi changed a Hammer ioctl, and the buildworld is needed to keep everything in sync.
The last bits of Linux emulation have been removed from DragonFly. It’s 32-bit, so it’s been unsupported since DragonFly went to 64-bit only with the 4.0 release. Also, some other 32-bit only items are gone, including the cs, ep, ex, fe, and vx network drivers. It’s almost impossible that anyone was using it, but it’s notable because that’s some… 15-20k lines of code gone? Removal of unused code is also positive.
Alex Merritt noticed that one of the new characteristics of DragonFly 4.6 was “improved IPI signalling”. He asked about benchmarks, Sepherosa Ziehau pointed at tools, and Matthew Dillon provided some results.
Because this always happens just after I create a DragonFly release, there’s a new version of OpenSSL. However, this is for version 1.0.2. 1.0.1 is what’s in the release, and it’s supported through the end of the year.
OpenSSH has a major version bump in DragonFly, to 7.3p1. This means some features – specifically patches for High Performance Networking – are no longer there, and you’ll get an error if your config file requires them. Either remove the options from your config, or install OpenSSH from dports.
Did you know that ACPICA has its own internal ‘coding language’, called AML? I did not, but it’s in DragonFly now in any case. Every program eventually grows big enough to read email, and every specification eventually includes its own programming segment.
Here is some coverage of the DragonFly 4.6 release, which may be interesting to read because of the comments: Hacker News, Hacker News again, and lobste.rs.
A reaction to the initial creation of DragonFly I never saw before, and Matthew Dillon’s followup. (via)
I like the summary in the very first comment of this story on DragonFly removing page-zeroing.
Thanks to a reminder from IRC user ‘cgag’, I’ve put an uncompressed ISO image of DragonFly 4.6 up on the main site. It’s linked on the download page, and should be available within 24 hours on the mirrors. If you are buying service from a virtual host provider, and can install an operating system directly from a downloadable URL, this is for you.
After some testing of different ways to pre-zero out memory pages, Matthew Dillon came to the conclusion: page zeroing doesn’t matter any more. The idea dates all the way back to CSRG, and he’s removed it from DragonFly.
DragonFly 4.6 is officially released! Download from your nearest mirror, or update your source files and build – my users@ email describes the steps.
I did all of this in a hour, because I had so many tabs saved from during the week. Don’t get overwhelmed!

I’m a bit late on this, but: If you are using DragonFly-current, you will need to rebuild world. If you are on 4.4, this won’t matter until you go to 4.6, and you’d be rebuilding world and kernel for that anyway.
(4.6 will probably be tagged this weekend.)
DragonFly 4.6 release candidate 2 has been tagged. You can pull it directly from the master site in img or iso form (check your local mirror instead if possible), or shift to the new tag.
“Where is RC1?” you may ask? I tagged the first release candidate some days ago, and this bug was immediately found right after. It was easier to go right to RC2 once a fix was found.
This candidate will probably lead directly to a release version, so if you want to run the release version exactly, wait a few days.
Matthew Dillon added NVMe support recently, and he also made some changes to DragonFly’s I/O system. His test system was able to reach over a million IOPS. That’s bananas!
the i915 support in DragonFly now matches the Linux 4.4 kernel, which is good news if you have a Broxton, Skylake, or Cherryview processor, plus it adds a variety of fixes.
