But it's not a potentially-breaking change. For example, on Debian
Wheezy, there are a huge number of packages that depend on "python (<<
2.8)", because they expect Python 2.7 and *not* Python 2.8. A newer
version 2.7 will satisfy that; a version 2.8 won't, because it's
entirely possible that 2.8 will have something that's significantly
different. That's what version numbers mean; Python follows the
standard three-part convention, where you upgrade automatically only
within the last part of the number.
