C++ Specific Information

Versioning

The Keypop C++ implementation is a transposition of the Java version. As a result, the C++ version may lag behind the Java version by one or more release cycles.

To make version correspondence explicit:

  • The Java implementation follows Semantic Versioning (SemVer) with three digits:
    MAJOR.MINOR.PATCH
  • The C++ implementation uses four digits:
    MAJOR.MINOR.PATCH.CPP_FIX

In this scheme, the first three digits of the C++ version reflect the corresponding Java source version, while the fourth digit represents any C++-specific fixes or adjustments.
