Diffusion releases are numbered according to the following scheme: X.Y.Z_Q. Each of the digits has the following significance:
- X is the major release number. Diffusion major releases incorporate significant new features and functionality over previous major releases. Diffusion major releases are typically made around the lifecycle of a year.
- Y is the minor release number. Diffusion minor releases incorporate bug fixes and minor features and functionality improvements. Diffusion minor releases are typically made around the lifecycle of a quarter.
- Z is the patch release number. Diffusion patch releases only incorporate bug fixes. Patch releases never contain new features. Patch releases are produced on an ad-hoc basis.
- Q is the internal build number and typically not relevant to customers.
