There will be breaking changes as Meteor moves from 0.6.5.1 to 0.7 to 0.8 up until it reaches 1.0. This is part of the bargain of working with pre 1.0 software (APIs etc. will be stabilized once 1.0 is reached).

I have found these "breaks" are minor and usually require a few minutes to fix. That said, I also tend to lag behind by a few weeks as other in the community work through the details of the breaking changes.

Meteor Hacks (http://meteorhacks.com) and EventedMind (https://www.eventedmind.com) are two great resources.
