Changes and Versioning

Changes to each version are documented in our CHANGELOG.md.

In December 2018 we introduced Semantic Versioning.

Given a version number MAJOR.MINOR.PATCH, we increment the:

  1. MAJOR version when we make incompatible changes:
    • That is we introduce changes to the rules which will DEFINITELY not validate previously generated XML which was valid to previous major version anymore
  2. MINOR version when we add functionality
    • That is we introduce changes to the rules which widen the scope of valid content (e.g. we add new codelist terms or accept new optional XML elements).
    • CAUTION: This might break YOUR validation scenario and ability to accept XML content
  3. PATCH version when we make backwards-compatible bug fixes.
