+snowplow-utils 0.15.0 (2023-09-19)
+---------------------------------------
+## Summary
+This full release introduces new "base" macros which are used to recreate the `snowplow_base_events_this_run` and related tables. It gives you the option to customise your session and user identifiers, your partitioning timestamps, and much more. Additionally, we remove the deprecated `snowplow_incremental` materialization that was removed in `0.14.0`, and we add multi-version support for the `get_field` macro for BigQuery.
+
+We have documentation explaining the outlined changes in detail [here](https://docs.snowplow.io/docs/modeling-your-data/modeling-your-data-with-dbt/) that you can use to explore the base macro changes in particular. For information about how to do this, see our [Advanced Usage of the Utils package](https://docs.snowplow.io/docs/modeling-your-data/modeling-your-data-with-dbt/dbt-models/dbt-utils-data-model/dbt-utils-advanced-operation/) page and the [utils configuration](https://docs.snowplow.io/docs/modeling-your-data/modeling-your-data-with-dbt/dbt-configuration/utils/) variables.
+
+Finally, before we dig into the details, starting with this version all future releases of our dbt packages will be released under the [Snowplow Community License](https://docs.snowplow.io/community-license-1.0/) instead of the Apache 2 license. For what this means for you, check out our [FAQ](https://docs.snowplow.io/docs/contributing/community-license-faq/), and our [announcement blog](https://snowplow.io/blog/license-changes-for-snowplow-open-source/).
