AddressBase Islands November 2024 – Epoch 114

This release note provides information about the November 2024 release of the AddressBase Islands products. These products were released to customers on 07 November 2024.

Update to the location of AddressBase technical documentation and release notes

AddressBase family product technical documentation (including technical specifications, release notes, getting started guides, etc.) is now available on the new OS Download Products’ Documentation Platform. This platform is the new central location for all technical documentation for OS Premium and OpenData Download products (such as AddressBase, OS MasterMap Topography Layer, OS Open UPRN, etc.).

Over the next few months, the old PDFs containing product technical documentation will be removed from the product pages of the OS website and replaced by links to the refreshed documentation on the new platform.

Release notes for AddressBase products are available on the new platform; simply navigate to the new platform and click Addressing and location portfolio > AddressBase Core Principles > Release Notes. Static PDF release notes for the AddressBase products will be replaced by digital release notes on the new platform over the next few months.
