October 2024
This release note provides information about the October 2024 release of Boundary-Line.
Customer information
Due to the recent coastline improvements that have been made, there are additional polygon vertices present in this release. If this causes any issues for you when loading the data, please let us know.
In the May release, due to an internal update to a system, the Unit IDs were all changed. These IDs have now been restored.
The attribute order found in the Shapefile format of this release have been updated to meet the attribute order stated in the product spec.
Product enhancements
1. In line with the exit of the United Kingdom from the European Union, the European Region layer has been frozen as of 1 April 2021 (no edits have been made to the European Region extents since 31 December 2020, but there were some minor coastline edits up to 1 April 2021). This frozen layer is available as a supplementary Historical European Region layer within Boundary-Line.
2. For the purposes of Boundary Review, the extents of the European Regions in England have been retained in the Boundary-Line product and will be maintained as an English Region layer.
3. For customers who used the European Region layer to represent a national extent for Scotland and Wales, a new Country Region layer is available as a supplementary layer in Boundary-Line. This will be a maintained layer and represents the national extents of England, Scotland and Wales.
4. Boundary-Line is now released in vector tile (MBTiles) format as of October 2021.
5. Boundary-Line has updated the legal name of the National Assembly for Wales to Senedd Cymru/the Welsh Parliament.

Data issues
The Global_Polygon_ID attribute is not present in the vector tile format of Boundary-Line at this release. All other formats are unaffected by this issue. This will be rectified for the subsequent release of Boundary-Line.

Boroughs
Previously, the reference to boroughs has not been included in the Boundary-Line product. In striving to improve the product, and at the request of the end users, the inclusion of a reference to the boroughs will enable users to search within their GIS and locate them more easily. This addition was introduced in October 2006.
These additions only apply to England and affect the districts that have been granted Charters of Incorporation (CoI), unitary authorities that have been created from previous districts with CoI, and metropolitan districts that have borough status. The tables below identify where _ (B) has been added to the file name and (B) to the boundary data. This addition does not affect the structure or specification of the product and will not impact on your GIS or translation software.
