In rails 4, images and fonts in vendor/assets no longer precompiled automatically

For me, after adding spree_fancy, I copy icons fonts into app/assets/fonts and copy bx_loader.gif & controls.png into app/assets/images

I see that bootstrap_sass gems also kept the fonts in vendor/assets/fonts folder but it precompiled automatically.
