Assets don't update with hmr when assets file is changed.It is happend with two backgorud ways.

1. Just use in sfc template with <img src="/public/a.svg" />. Reson:It need analyze assets reference in vue file.But it not support on now.It may be stuff to do.

2.Use in sfc script with import a from './public/a.svg' It is not work with hmr. Reson: it not update component (has static props (like {a: './public/a.svg' }) ) with hmr reload is triggered. Soultion:
-Maybe can unmount component and remount new component. May add hmr api.like vue-remount to reslove this. -Maybe just full reload with page.

I believe that this problem has already been solved. I just tested it with version 0.20.2 and I couldn't reproduce it.

@underfin Please provide a link to a repo that can reproduce the problem you ran into.

Yeah.This case can work with import a from './public/a.svg'. But use in sfc template with <img src="/public/a.svg" /> is still not work with hmr.
