Linux creator Linus Torvalds announced the first release candidate for the upcoming 2.6.18 kernel, "the merge window for 2.6.18 is closed, and -rc1 is out there". He noted that the changes are extensive, "the changes are too big for the mailing list, even just the shortlog. As usual, lots of stuff happened. Most architectures got updated, ACPI updates, networking, SCSI and sound, IDE, infiniband, input, DVB etc etc etc." Find the shortloghere. Linus went on described additional changes:
"There's also a fair amount of basic infrastructure updates here, with things like the generic IRQ layer, the lockdep (oh, and priority-inheritance mutex support) stuff by Ingo&co, some generic timekeeping infrastructure ('clocksource') stuff, memory hotplug (and page migration) support, etc etc."
