Seems to compile fine under x64 Linux and a Plan 9 Qemu VM.

Regarding the ARM, I failed to compile it on 9pi (Plan 9 for the Raspberry Pi) though I think it should be fine in Raspbian. It's possible you'll want to pull from tip to get it running in 9pi but I haven't tried it myself. Mind you Plan9 support seems unofficial for now.

I think people already complained about posting minor version updates.

If you have to post minor version updates, link to the changelog, not the downloads page.

This Sir, is a sound advice..

Then surely those people won't vote it up.

I suspect some people automatically upvote anything pertaining to Go, which is probably a stronger force than those flagging the post (especially at 3 AM ET)

No, they'll flag it.
