Upcoming changes can be found on the improvements roadmap page.

For a more long-term history, please see the GOV.UK GA4 annotations report.

January 2025

New canonical URL field

A page’s canonical URL is captured in a new field/custom dimension sent with all events. This is available in the GOV.UK GA4 property, the Data API, and in BigQuery in both the raw and flattened datasets.

traffic_type parameter added to the GOV.UK GA4 flattened dataset

The traffic_type parameter is available in the GOV.UK GA4 flattened dataset to support analysis of GOV.UK GA4 data filters.

Resolved issues with some custom dimension fields in the GOV.UK GA4 flattened dataset

Issues with the query_string, ui_text, response, search_term, autocomplete_input, autocomplete_suggestions, and link_text fields in the GOV.UK GA4 flattened dataset have been resolved in the data processing going forwards. The processing for these fields was only including string values, but we observed that some data was coming through as having an integer or double data type. We have now edited the processing so that integer and double type data will be included in these fields in the flattened table.

Taxonomy dimensions renamed in the GOV.UK GA4 flattened dataset

Four taxonomy dimensions have been renamed in the GOV.UK GA4 flattened dataset to help users find the correct fields. taxonomy_all_DEPRECATED has become taxonomy_all and taxonomy_all_ids_DEPRECATED has become taxonomy_all_ids, as these are the fields containing current taxonomy information. full_taxonomy has been renamed full_taxonomy_DEPRECATED and full_taxonomy_ids has been renamed full_taxonomy_ids_DEPRECATED because these fields have not been populated since November 2023.
