DragonFly is an operating system and environment designed to be the logical continuation of the FreeBSD-4.x OS series. These operating systems belong in the same class as Linux in that they are based on UNIX ideals and APIs. DragonFly is a fork in the path, so to speak, giving the BSD base an opportunity to grow in an entirely new direction from the one taken in the FreeBSD-5 series. Dillon started DragonFly in the belief that the methods and techniques being adopted for threading and symmetric multiprocessing in FreeBSD 5 would lead to poor system performance and cause maintenance difficulties. He sought to correct these suspected problems within the FreeBSD project. Due to ongoing conflicts with other FreeBSD developers over the implementation of his ideas, his ability to directly change the FreeBSD codebase was eventually revoked. Despite this, the DragonFly BSD and FreeBSD projects still work together contributing bug fixes, driver updates, and other system improvements to each other. Intended to be the logical continuation of the FreeBSD 4.x series, DragonFly's development has diverged significantly from FreeBSD's, including a new Light Weight Kernel Threads (LWKT) implementation, a lightweight ports/messaging system, and feature-rich HAMMER file system. Many concepts planned for DragonFly were inspired by the AmigaOS operating system.
NB:- Latest stable version of the software will be delivered.
The DragonFly BSD project, a former fork of FreeBSD which is now independently developed, has released a new version: DragonFly BSD 4.6.0. This new release offers a series of incremental updates, including improved accelerated video, better SMP performance and enhanced networking performance under heavy loads. "DragonFly version 4.6 brings more updates to accelerated video for both i915 and Radeon users, home-grown support for NVMe controllers, preliminary EFI support, improvements in SMP and networking performance under heavy load, and a full range of binary packages. The i915 driver has been updated to match the version found with the Linux 4.4 kernel. This gives us significantly better stability on newer CPUs, Broadwell and Skylake in particular. The Radeon driver has been updated to match Linux 3.18, and controls for the backlight are available through drm.radeon.backlight." This release of DragonFly BSD also features over 24,000 third-party ports and introduces EFI support for 64-bit x86 hardware.
Justin Sherrill has announced the release of DragonFly BSD, the latest stable release from the BSD-derived operating system that features the Hammer file system, virtual kernels and other unique characteristics. This first point release in the stable 4.4 series is provided due to the late inclusion of an important OpenSSL security update: "DragonFly BSD 4.4 has been tagged and built. DragonFly version 4.4 brings further updates to accelerated video for both i915 and Radeon users, a new locale system, and a new default linker. Significant behind-the-scenes work has also been done, with symbol versioning, Hammer1 improvements, and other changes. Version 4.4.1 was the first release due to the late inclusion of OpenSSL update 1.0.1q. ... If you have an existing 4.2.x system and are running a generic kernel, the normal upgrade process will work. Change your local /usr/src to 4.4.".
The DragonFly BSD team has announced the launch of DragonFly BSD 4.2.0. The new release includes a number of important new features and upgrades. DragonFly BSD 4.2.0 includes GNU's GCC 5 compiler as the default system compiler, offers improved graphics support and Sendmail has been replaced by a home-grown, minimal mail transfer agent. "Sendmail has been replaced by the home-grown DragonFly Mail Agent (DMA) in the base system. DMA is not a full-featured MTA (Mail Transfer Agent), it only accepts mails from local MUA (Mail User Agents) and delivers them immediately, either locally or remotely. DMA doesn't listen to network connections on port 25. People who still need a full-featured MTA must install it from dports. OpenSMTPD, Postfix and Sendmail itself are available as binary packages." DragonFly BSD's audio stack and packet filter have been updated with code ported in from FreeBSD's development branch.
Justin Sherrill has announced the release of DragonFly BSD 4.0.1, the first stable 4.0 build of the project's UNIX-like operating system created in 2003 by Matthew Dillon as a fork of FreeBSD 4.8: "Version 4.0.1 released 25 November 2014. Version 4 of DragonFly brings Haswell graphics support, 3D acceleration, and improved performance in extremely high-traffic networks. DragonFly now supports up to 256 CPUs, Haswell graphics (i915), concurrent pf operation, and a variety of other devices. As announced during the 3.8 release, DragonFly BSD is 64-bit only. No 32-bit installation images have been generated, and no compatibility work is being done for 32-bit systems. Changes since DragonFly 3.8: new device files /dev/upmap and /dev/kpmap have been added. These memory mappable drivers allow for a per process or common to the kernel shared memory space. The objective is to allow kernel-provided information to be directly read from memory, without having to pay the cost of a traditional system call.".
Justin Sherrill has announced the release of DragonFly BSD 3.8.0, a new version of the UNIX-like operating system created in 2003 by Matthew Dillon as a fork of FreeBSD 4.8. From the release announcement: "DragonFly release 3.8. Big-ticket items: dynamic binaries in the root file system; DragonFly binaries in /bin and /sbin are now dynamic, which makes it possible to use current identification and authentication technologies such as PAM and NSS to manage user accounts; some libraries have been moved to /lib to support this; USB4BSD is now default in DragonFly, USB3 devices are supported, though some network devices may not be recognized; the drm/i915 driver had originally been ported from FreeBSD, an ongoing synchronization work with the version present in the Linux 3.8 branch is now going on."
DragonFly BSD 3.6.0, a UNIX-like operating system created in 2003 as a fork of FreeBSD 4.8, is out: "Version 3.6.0 released." Big ticket items of the release include: "Dports, which uses the FreeBSD ports system as a base, and the 'pkg' tools for installation, is now default on DragonFly; using the parallel building of the 20,000 packages in dports as a test case, contention in the kernel has been nearly eliminated; support for newer Intel and ATI chipsets is present in the system - this may not work for every hardware combination, but a number of users have reported success with hardware-accelerated video using this update; locales and libiconv work have brought DragonFly up to date on language support, utilities should be usable in your native language.".
