Chapter 7. Developing SystemImager®

7.1. Version Strings

SystemImager releases use a X.Y.Z numbering scheme. X is a major feature release revision , incremented to show significant architecture changes. Y is a minor release revision, incremented to show the addition of new features. Z is a bug-fix revision. SystemImager uses a versioning scheme similar to that used by the linux kernel. If Y is an odd number, the release is a development release. If Y is even, it is a stable release.

Using this scheme, you can easily see that 2.1.3 is a development release because 1 is odd. You can assume that the only changes between 2.0.3 and 2.0.4 were bug fixes, because only the last digit was incremented.
