Package Versioning

Each package version is composed of 4 period-delimited numbers - represented here by the letters M, m, p and b [M.m.p.b]. The table below provides a descriptive reference regarding package version numbering.

Digit	Meaning	Description
1 (M=Major)	Major revision	Incremented when the new version is substantially different from the previous For example, a new module added or an existing module's algorithm significantly altered.
2 (m=minor)	Minor revision	Incremented when the new version has changed but not in a major way. For example, some minor changes in the API or feature set.
3 (p=patch)	Patch number	Incremented for all other source code changes. This include any packaging support code.
4 (b=build)	Build number	Incremented for each release delivery to CM. Reset for any change to M, m or p
