Versions & changelog

Versioning​

Our versioning policy follows the Semantic Versioning specification. In our case, given a version MAJOR.MINOR.PATCH, we increment the:

  • MAJOR version when the data model of the Graph changes
  • MINOR version when the pipeline (e.g., different deduplication method, different implementation for an enrichment process) or major data sources change
  • PATCH version when the graph data are updated

Changelog​

This section documents all notable changes for each graph version.

v9.0.0​
