Yep and dropped 32bit support.

In most peoples view, long overdue. There are some specialist distro's for old hardware, there is zero reason for most niche distro's to bother supporting it. It's been 5+ years now that even low end Celeron and Atom processors have 64-bit support, even longer since everything AMD makes supported 64-bit, absolutely ludicrous for a small team like siduction to continue to put out 32-bit distro for the few holdouts who refuse to migrate to 640-bit, or who manage to have old enough hardware to not support it. Those people can move to niche products such as anti-x that's geared towards older hardware, or upgrade to something far more energy efficient and probably 3x more powerful clock for clock and run 64-bit.

While I believe in not IMMEDIATELY cutting off older technology, at this point there is no purpose to continuing to support 32-bit x86 architecture for the small distros. I still think Debian should continue (as they probably will for quite a few years), but the smaller couple person distro's based off it, I think it's overdue to quite putting forth the time and effort to support 32-bit.

Mmmmmmmmmmmmmm I think you will find the number of people still using 32bit machines is still very high and hardly a few "holdouts" as you suggest. For one thing not everyone is in a position afford a new computer and anyway I won't be parting with my Thinkpad anytime soon.

Like I said, it's not new computers that support 64-bit. Everything powered by an AMD or Intel chip in the last 5 YEARS (which is just a hair shorter than the national average that people keep computers/laptops according to most reports) supports 64-bit. AMD actually has supported it in every one of their chips for something like 7 years now. Even before that 5 years, MOST of Intels chips supported 64-bit. Their mainline processors have been 100 64-bit since the core2 architecture (2006, 10 years ago). Only their Atom architecture and those chips based on it continued to be 32-bit. Every person I know in person running 32-bit, HAS a 64-bit capable pc, they just CHOOSE to still run 32-bit. Which is fine, I think it's just foolish for small, specialty distro's to bother supporting it still given there's been no new x86-only hardware made by the #1 or #2 company that doesn't support 64-bit in such a moderately long time.
