...so why not just replace "squeeze -> stable" with "6.0
The current version number for Squeeze is 6.0.4. The version number has been bumped because fixes have been applied to the base release of 6.0 since it was released. When it's considered that enough fixes, or significant fixes have been applied to the base version to make it substantially different to the base release 6.0 it'll get bumped up to 6.1. The number of versions of a release can't be predicted because the number of bugs and therefore the corresponding number of fixes can't be predicted.
