BSD and Darwin derivatives This release supports a much larger variety of hardware and multiprocessor systems than previous releases, thanks to updates of ACPI and APIC and ACPI interrupt routing support. Hammer volumes can now deduplicate volumes overnight in a batch process and during live operation. The 'hammer dedup-simulate' command can be used to estimate space savings for existing data. DragonFly now uses gcc 4.4 as the default system compiler, and is the first BSD to take that step. DragonFly now offers significant performance gains over previous releases, especially for machines using AHCI or implementing swapcache(8).

gcc 4.4 as the default system compiler

I am glad to see DragonFly BSD taken huge steps forward: the SMP work is very important, and Hammerfs continues to progress.

I think the comment about Dragonfly being the first BSD to update to gcc 4.4 makes little sense though: the other BSDs have taken a stance against the GPLv3 so Dragonfly may very well be the *only* BSD to take that step. But then, Debian GNU/kFreeBSD was probably there first?

In any case the real race seems to be who will be the first BSD to use CLANG as it's default compiler.
