- 64-bit vkernels now work on 64-bit boxes
- The T/TCP extension is no longer supported
- Updated BIND to 9.5.2-P3 incl. DNSSEC support available by default
- Updated SENDMAIL to 8.14.4
- Updated wpa_supplicant to 0.6.10
- Updated hostapd to 0.6.10
- Updated groff to 1.20.1
- Updated file to 5.04
- Updated ncurses to 5.7
- Updated top to 3.8beta1 including DragonFly specific patches
- Updated less to 436
- Updated openssh to 5.3p1 (with HPN patch)
- Updated gcc 4.4 to 4.4.2
- Added binutils 2.20
- Added cryptodev support to OpenSSL
- ssh server: change defaults for new installations to disallow plain text passwords and allow root login via public key
- This is a mechanism which allows an attached solid state drive to be used to cache data and/or meta-data for other filesystems. The meta-data caching feature is particularly useful for machines which manage millions of files. About 2 million inodes and their related blockmaps can be cached per gigabyte of SSD. DragonFly supports up to 32GB of swap, per swap device (up to four) on i386, and up to 512GB of swap, per swap device, on 64-bit, so a very large number of inodes can be cached. Please see the swapcache( 8 ) manual page for more information.
- Our filesystem now supports a REDO log on top of the UNDO log it already had. The filesystem will use the REDO log forward-log write and file-extend operations which allows fsync to accomplish its goals with only REDO log writes. This greatly improves the speed of fsync without weakening HAMMER's fast-recovery feature.
- The tmpfs port we did from NetBSD is able to fully utilize the VM page cache on the system as well as swap space, with no duplication of data (unlike MFS) and very good cache characteristics which reduce or eliminate disk activity under nominal operation.

DragonFly Release 2.10
Najnovije izdanje iz DragonFly BSD kuce, sa mnogo novina, najvaznije su izlistane dole:
Hardware and multiprocessor support - 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 Deduplication - 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.
Packet Filter (pf) - Pf was updated to a version based upon OpenBSD 4.4. The previous version of pf in DragonFly was based on OpenBSD 4.2.
Compiler updates - DragonFly now uses gcc 4.4 as the default system compiler, and is the first BSD to take that step.
New bridging functionality - The bridging system has been rewritten. Multiple interfaces on a single system can be bound together transparently under a single virtual MAC address, and bandwidth aggregated to that new interface.
MP Performance - The MPLOCK (the primary lock, that when held ensures only a single cpu is operating within the kernel) has been removed from every area except the VM system. DragonFly is one of the few non-academic operating systems to use a primary sychronization mechanism that is not a blocking mutex
Overall Performance - DragonFly now offers significant performance gains over previous releases, especially for machines using AHCI or implementing swapcache(.
ACPI Support - Major update to DragonFly's ACPI support have been made, particularly for interrupt routing.
Pored toga jos i OpenBSD pf iz 4.4, kriptovanje root i swap particije prilikom instaliranja sistema, podrska do 63 procesora i ukupno 512 GB RAM-a na 64-bitnoj platformi, pkgsrc-2011Q1 paketi, GCC 4.4.5...
DraognFly BSD dolazi u formi .iso imidza za 32-bitne i 64-bitne platforme, kao butabilni usb imidz, ili butabilni usb imidz sa X okruzenjem.
