Este tópico irá servir para notificar à comunidade os desenvolvimentos e as actualizações do kernel Linux. Irão ser aqui colocadas apenas as releases das versões stable, e este post irá ser actualizado conforme novas versões forem saindo. Iremos ter em conta as versões 2.6 e 2.4 pois ambas ainda estão em estado de desenvolvimento.

Este tópico irá ter apenas um caracter informativo, portanto, não deverão ser colocadas dúvidas relativas à compilação dos kernels.

E a 2.6.26 finalmente cá fora :)

"It's been almost three months since 2.6.25 (87 days to be exact, I think), making this a longer-than-usual release cycle. Or maybe it just feels that way, and we're always getting close to three months these days," said Linux creator Linus Torvalds, announcing the 2.6.26 Linux kernel, adding, "but it's out there now." He continued:

"The diffs from -rc9 are pretty small, with with the bulk actually being Documentation updates (almost 80% is just added docs). The rest tends to be one-liners for some regressions or otherwise pretty small patches. Several regressions did get fixed in the last few days, thanks to everybody involved."

Click the 2.6.26 tag to review all the previous release candidate announcements building up to this release. Source level changes can be reviewed via Linus' 2.6 gitweb kernel tree (http://git.kernel.org/gitweb.cgi?p=linux/kernel/git/torvalds/linux-2.6.git;a=summary). The latest kernel can be downloaded from the Linux Kernel Archives.

KernelTrap (http://kerneltrap.org/Linux/2.6.26_A_Longer-Than-Usual_Release_Cycle)

We were up to nine release candidates (http://www.phoronix.com/scan.php?page=news_item&px=NjU3MQ) with the 2.6.26 branch (http://www.phoronix.com/scan.php?page=search&q=Linux+2.6.26) but today the Linux 2.6.26 kernel has been released. Since 2.6.26-rc9 were mostly documentation updates and a few regression fixes. The Linux 2.6.26 kernel x86 PAT, PCI Express Active State Power Management, KVM support for IA64 and PPC architectures, basic para-virtualization support for KVM, a UVC web-camera driver, OLPC support, new hardware drivers, and more. This kernel also brings updated ATI and Intel DRM (http://www.phoronix.com/scan.php?page=news_item&px=NjUzOQ), which includes the initial R500 3D support (http://www.phoronix.com/vr.php?view=12399). A nice list of the changes for the Linux 2.6.26 kernel can be found at KernelNewbies.org (http://kernelnewbies.org/Linux_2_6_26). The Linux 2.6.26 kernel announcement can be read at LKML.org (http://lkml.org/lkml/2008/7/13/216).

E uma actualização da série 2.4: 2.4.36.7

Já saiu a 2.6.26.5 por causa de um problema no 2.6.26.4

http://lwn.net/Articles/297361/

Verdade. O problema foi um patch mal aplicado, e foi corrigido em +- 6 horas. Nada mau :p
Actualizado :)

Linux 2.6.27

So not a lot happened after -rc9, which is mostly good. I certainly don't
want to have any upheavals at the end of an -rc series, although I
wouldn't have minded more people looking at the regression list. That
said, I think we're in pretty good shape, and it's not like I can hold
back releases indefinitely anyway.

The shortlog from -rc9 really is small, and I doubt many people will
notice the changes. And as usual, if you want to know about the big
changes since 2.6.26, the full ChangeLog is available, but people are
much better off with the human-readable explanations at

http://kernelnewbies.org/LinuxChanges

but most important is obviously to just test it. Especially if you've been
a bad boy (or girl) and haven't been testing the -rc's.

Linux 2.6.27 kernel released 9 October 2008.
Note: The 2008 Linux Kernel Summit was held September 15 and 16 in Portland, Oregon, immediately prior to the Linux Plumbers Conference. LWN, as always, has excelent coverage of the event (http://lwn.net/Articles/KernelSummit2008/). You can download here all the papers (http://www.linuxsymposium.org/2008/archives.php) of the conferences in two PDF files. LWN also has coverage of the Linux Plumbers Conference (http://lwn.net/Articles/299763/)
