Asset versioning in production

[assafweinberg]

This might be a silly question, but I noticed that in non-production mode, there's a ?v=[timestamp] at the end of each asset, but in production mode its always ?v=0. This seems to mean that every time I deploy new code, I also have to manually invalidate the cache to get the new assets loading in production. Is that right, or should production assets also have a ?v=[timestamp] and automatically be updated without invalidation?

Is that fixed in 0.2.9 ?
