Yes, this is probably the most accurate expression.

In the apt source 'preliminary-stable-builds' packages are based on 'r14.0.x' 
GIT branch == basis for maintenance releases R14.0.1, R14.0.2, etc. In short, 
focused on the stable releases.

In the apt source 'nightly-builds' packages are based on the 'master' GIT 
branch == basis for a future release R14.1.0. In short, focused on the 
development of new features - may be unstable.
