# 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. This page is going to replace the updates listed until the end of 2022 on the OpenAIRE website at https://www.openaire.eu/aggregation-and-content-provision-workflows
