Package Versioning and Compatibility

Compatibility Keys

Compatibility keys serve two primary purposes:

  1. Enable tooling to identify incompatibilities between components
  2. Convey a level of compatibility between different releases to set end user expectations.

Each compatibility key is composed of 4 comma-delimited numbers - represented here by the letters M, S, R and P [M,S,R,P]. The table below provides a descriptive reference for compatibility key intention.

Compatibility Key Reference
Key Meaning Description
1 (M=Major) Break in compatibility The package consumer is required to re-write the calling source code to use the package
2 (S=Source) Source compatibility The package consumerís source code doesn't require change, but does require a recompile
3 (R=Radix) Introduction of new features Compatibility with previous interfaces is not broken. If libraries are provided by the package, an application must re-link with the new libraries, but is not required to recompile its source
4 (P=Patch) Bug fixes only If libraries are provided by the package, an application must re-link with the new libraries, but is not required to recompile its source.


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.

Package Version Reference
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
