"We are pleased to announce the official release of OpenBSD 4.3," began OpenBSD creator Theo de Raadt. "This is our 23rd release on CD-ROM (and 24th via FTP). We remain proud of OpenBSD's record of more than ten years with only two remote holes in the default install." He added, "as in our previous releases, 4.3 provides significant improvements, including new features, in nearly all areas of the system". Four platforms were listed as new or extended, including: sparc64 gained SMP support, "this should work on all supported systems, with the exception of the Sun Enterprise 10000"; hppa K-class servers are now supported; mvme88k gained SMP support on a couple of systems, and support for the 88110 processor was added. Numerous drivers were listed as new or improved, including a huge list of network drivers:

"The bge(4) driver now supports BCM5906/BCM5906M 10/100 and BCM5755 10/100/Gigabit Ethernet devices; the cas(4) driver now supports Cassini+ 10/100/Gigabit Ethernet devices; the em(4) driver now supports ICH9 10/100 and 10/100/Gigabit Ethernet devices; the gem(4) driver now supports the onboard 1000base-SX interface on the Sun Fire V880 server; the ixgb(4) driver now supports the Sun 10Gb PCI-X Ethernet devices; the msk(4) driver now supports Yukon FE+ 10/100 and Yukon Supreme 10/100/Gigabit Ethernet devices; the nfe(4) driver now supports MCP73, MCP77 and MCP79 10/100/Gigabit Ethernet devices; the ral(4) driver now supports RT2800 based wireless network devices; the cmpci(4) driver now supports CMI8768 based audio adapters; the it(4) driver now supports ITE IT8705F/8712F/8716F/8718F/8726F and SiS SiS950 ICs; new bwi(4) driver for the Broadcom AirForce IEEE 802.11b/g wireless network device; new et(4) driver for the Agere/LSI ET1310 10/100/Gigabit Ethernet device; new etphy(4) driver for the Agere/LSI ET1011 TruePHY Gigabit Ethernet PHY; new iwn(4) driver for the Intel Wireless WiFi Link 4965AGN IEEE 802.11a/b/g/Draft-N wireless network device; new upgt(4) driver for the Conexant/Intersil PrismGT SoftMAC USB IEEE 802.11b/g wireless network device."

A more complete list of changes can be found here. ONLamp also recently posted an interview titled, "Puffy and the Cryptonauts: What's New in OpenBSD 4.3". Theo noted, "profits from CD sales are the primary income source for the OpenBSD project -- in essence selling these CD-ROM units ensures that OpenBSD will continue to make another release six months from now."

"It's been long promised, but there it is now," began Linux creator Linus Torvalds, announcing the 2.6.25 Linux kernel. He continued, "special thanks to Ingo who found and fixed a nasty-looking regression that turned out to not be a regression at all, but an old bug that just had not been triggering as reliably before. That said, that was just the last particular regression fix I was holding things up for, and it's not like there weren't a lot of other fixes too, they just didn't end up being the final things that triggered my particular worries." Linus added:

"The full changelog from 2.6.24 is 7.5M, with a 12MB compressed patch. Tons and tons has changed, but if you've been following the -rc releases, you'll already know about the big things. The changes from the last rc (-rc9) are fairly small and mostly pretty trivial, and the shortlog is appended. So it's mostly one-liners, with some updates to drivers (net and usb) and to networking that are a bit larger (although a number of the driver updates are things like just new ID's etc)."

More information about the latest release can be found on the KernelNewbies Linux 2.6.25 wiki page.

"The latest feature release GIT 1.5.5 is available at the usual places," began Git maintainer Junio Hamano, adding "we kept this cycle just slightly over two months, as the previous 1.5.4 cycle was painfully tooooo long."

Git is a distributed version control system that was originally written by Linus Torvalds in April of 2005. It was written to be only a temporary replacement for BitKeeper, which Linus had been using to manage kernel source code since February of 2002. Junio Hamano took over maintainership of Git in July of 2005, and the tool has long since become quite popular outside of even Linux kernel development. Regarding the latest stable release, Junio highlighted some of the changes, including:

"Comes with git-gui 0.10.1; bunch of portability improvement patches coming from an effort to port to Solaris has been applied; 'git fetch' over the native git protocol used to make a connection to find out the set of current remote refs and another to actually download the pack data. We now use only one connection for these tasks; 'git commit' does not run lstat(2) more than necessary anymore; bash completion script (in contrib) are aware of more commands and options; a catch-all 'color.ui' configuration variable can be used to enable coloring of all color-capable commands, instead of individual ones such as 'color.status' and 'color.branch'; bash completion's prompt helper function can talk about operation in-progress (e.g. merge, rebase, etc.); 'git help' can use different backends to show manual pages and this can be configured using 'man.viewer' configuration; 'git gui' learned an auto-spell checking; 'git checkout' and 'git remote' are rewritten in C; two conflict hunks that are separated by a very short span of common lines are now coalesced into one larger hunk, to make the result easier to read."

"Hello everyone! We are happy to say that the 1.12 release is now available!" began Matthew Dillon, announcing the latest stable version of DragonFly BSD. The project's home page explains, "DragonFly is an operating system and environment originally based on FreeBSD. DragonFly branched from FreeBSD in 2003 in order to develop a radically different approach to concurrency, SMP, and most other kernel subsystems." Regarding the latest release, Matt explained:

"This release is primarily a maintenance update. A lot of work has been done all over the kernel and userland. There are no new big-ticket items though we have pushed the MP lock further into the kernel.

"The 2.0 release is scheduled for mid-year. Of the current big-ticket item work, the new HAMMER filesystem is almost to the alpha stage of development and is expected to be production ready by the mid-year 2.0 release."

Joseph Myers announced the availability of GCC 4.2.3 saying, "GCC 4.2.3 is a bug-fix release, containing fixes for regressions in GCC 4.2.2 relative to previous GCC releases." He adds, "as always, a vast number of people contributed to this GCC release -- far too many to thank individually!"

GCC is the GNU Compiler Collection which includes C, C++, Objective-C, Fortran, Java, and Ada compilers. Download GCC 4.2.3 from your nearest gcc.gnu.org mirror.

"The latest feature release GIT 1.5.4 is available at the usual places," began Git maintainer Junio Hamano. He continued, "it has been an unusually long cycle. 5 months since the last feature release 1.5.3 was really a bit too long. But I hope it was worth waiting for. Thanks everybody for working hard to improve it." He noted that there were 165 contributers resulting in 684 changed files, included 70,435 insertions and 28,984 deletions.

The Git distributed version control system was originally written by Linus Torvalds in April of 2005 to temporarily replace BitKeeper, which he had been using to manage kernel source code since February of 2002. Junio Hamano took over maintainership of Git a few months later, in July of 2005, and the tool has long since become quite popular outside of even Linux kernel development. Regarding the latest stable release, Junio highlighted some of the changes, including:

"Comes with much improved gitk, with i18n; comes with git-gui 0.9.2 with i18n; progress displays from many commands are a lot nicer to the eye; rename detection of diff family while detecting exact matches has been greatly optimized; 'git diff' sometimes did not quote paths with funny characters properly; various Perforce importer updates; 'git clean' has been rewritten in C; 'git push' learned --dry-run option to show what would happen if a push is run; 'cvs' is recognized as a synonym for 'git cvsserver', so that CVS users can be switched to git just by changing their login shell; 'git add -i' UI has been colorized; 'git commit' has been rewritten in C; 'git bisect' learned 'skip' action to mark untestable commits; 'git svn' wasted way too much disk to record revision mappings between svn and git, a new representation that is much more compact for this information has been introduced to correct this; in addition there are quite a few internal clean-ups."

"The release is out there (both git trees and as tarballs/patches), and for the next week many kernel developers will be at (or flying into/out of) LCA in Melbourne, so let's hope it's a good one," said Linus Torvalds, announcing the 2.6.24 Linux kernel. He noted, "nothing earth-shattering happened since -rc8". Source level changes can be viewed via the gitweb interface. A nice overview of all changes can be found at Kernel Newbies.

In a followup email, Linus added:

"Since I already had two kernel developers asking about the merge window and whether people (including me) traveling will impact it, the plan right now is to keep the impact pretty minimal. So yes, it will probably extend the window from the regular two weeks, but *hopefully* not by more than a few days."

"New year, new kernel: Linux 2.4.36 is finally ready and has been checked long enough to be released. Quite a bunch of bugs, build errors and security issues have been fixed since 2.4.35, but all of those fixes were merged into 2.4.35-stable," 2.4 maintainer Willy Tarreau stated, announcing the latest 2.4 stable Linux kernel. He noted, "I should say that I'm quite satisfied of this dual-branch release model which proves to be very successful at separating quick fixes from changes which require more thorough testing." Willy went on to add:

"Concerning future versions, I have nothing pending in the queue anymore. I will then go on with 2.4.36.X when bug fixes come in, and only open 2.4.37 when I get something which I do not consider suitable for 2.4.36.X."

The previous 2.4.35 stable kernel was released in July of 2007. Source level changes can be viewed through the linux-2.4 gitweb interface.

"We are pleased to announce the official release of OpenBSD 4.2. This is our 22nd release on CD-ROM (and 23rd via FTP). We remain proud of OpenBSD's record of more than ten years with only two remote holes in the default install," Theo de Raadt announced. In addition to a lengthy list of new features and improvements, the release announcement includes a dedication:

"We dedicate this release to the memory of long-time developer Jun-ichiro 'itojun' Itoh Hagino, who focused his life on IPv6 deployment for everyone. Without his BSD and IETF participation, IPv6 would not be where it is today. Only now people are becoming aware of his numerous contributions because he took credit for much less than he accomplished. The developers in our project will all miss him."

"Finally. Yeah, it got delayed, not because of any huge issues, but because of various bugfixes trickling in and causing me to reset my 'release clock' all the time. But it's out there now, and hopefully better for the wait," Linus Torvalds said announcing the 2.6.23 kernel. He noted few changes since the last release candidate, "not a whole lot of changes since -rc9, although there's a few updates to mips, sparc64 and blackfin in there. Ignoring those arch updates, there's basically a number of mostly one-liners (mostly in drivers, but there's some networking fixes and soem VFS/VM fixes there too)." Source level changes can be viewed via the gitweb interface. A nice overview of all changes can be found at Kernel Newbies. Linus went on to describe his plan going forward:

"I want this to be what people look at for a few days, but expect the x86 merge to go ahead after that. So far, all indications are still that it's going to be all smooth sailing, but hey, those indicators seem to always say that, and only after the fact do people notice any problems ;)"

"This version has a lot of corrections, and is stable at least on my machine," noted Linus Torvalds in the 0.11 Linux kernel release announcment, "I /hope/ every known bug is fixed, but no promises (and all unknown bugs are still there, probably with reinforcements ;-)". The 0.11 kernel was released on December 8th, 1991, gaining demand loading, the mkfs, fsck and fdisk utilities, improved floppy drivers, a console that could generate beeps, support for US, German, French and Finnish keyboards, and settable line-speeds for the com ports (instead of having them hard-coded to 2400bps). Noticeably lacking was support for SCSI, an init/login system (Linux 0.11 booted into a root bash prompt), and paging to disk:

"Although I have a somewhat working VM (paging to disk), it's not ready yet. Thus linux needs at least 4M to be able to run the GNU binaries (especially gcc). It boots up in 2M, but you cannot compile."

Matthew Dillon has announced the release of DragonFly BSD 1.10, the sixth major DragonFly release since the project's creation in 2003. The release notes say "we consider 1.10 to be more stable then 1.8," and summarize some of the new features:

"Several big-ticket items are present in this release. Our default ATA driver has been switched to NATA (ported from FreeBSD). NATAs big claim to fame is support for AHCI which is the native SATA protocol standard. It is far, far better then the old ATA/IDE protocol. DragonFly now has non-booting support for GPT partitioning and 64 bit disklabels. Non-booting means we don't have boot support for these formats yet. DragonFly's Light Weight Process abstraction is now finished and working via libthread_xu but the default threading library is not quite ready to be changed from libc_r yet. All threaded programs now link against an actual 'libpthread' which is a softlink to libc_r or libthread_xu, allowing the new threading library to be tested more fully."

"Do you pine for the nice days of minix-1.1, when men were men and wrote their own device drivers?" began the October 5th, 1991 announcement for Linux kernel version 0.02 on the comp.os.minix newsgroup. In the release notes, Linus Torvalds continued, "as I mentioned a month(?) ago, I'm working on a free version of a minix-lookalike for AT-386 computers. It has finally reached the stage where it's even usable (though may not be depending on what you want), and I am willing to put out the sources for wider distribution." 19 days after the 0.01 kernel was released, the 0.02 kernel debuted with the new-found ability to run a handful of utilities including bash, gcc, gnu-make, gnu-sed and compress. There was no floppy driver yet, the hard disk driver was hard coded to AT-compatible drives, and due to various buffer-cache problems it was not possible to compile large programs like gcc from a running 0.02 kernel. Linus noted:

"I can (well, almost) hear you asking yourselves 'why?'. Hurd will be out in a year (or two, or next month, who knows), and I've already got minix. This is a program for hackers by a hacker. I've enjouyed doing it, and somebody might enjoy looking at it and even modifying it for their own needs. It is still small enough to understand, use and modify, and I'm looking forward to any comments you might have."

"After 6 months of careful integration and testing, I'm happy to announce availability of Linux 2.4.35," 2.4 maintainer Willy Tarreau announced on the lkml. This is the second stable 2.4 kernel released since Willy became the 2.4 kernel maintainer nearly a year ago in August of 2006. Source level changes can be viewed through the linux-2.4 gitweb interface. Willy added:

"I'm very conscious that 2.4 has mostly left desktop PCs and notebooks, but it's still commonly found on servers, route reflectors or firewalls. For this reason, I'm open to merge the small updates required to maintain such systems running (eg: PCI IDs and such), but I will generally refuse all patches which add support for new desktop or notebook-specific hardware, unless the people present very convincing arguments. Those people generally would better upgrade their systems to 2.6."
