# AddressBase Islands November 2024 – Epoch 114

## 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](https://docs.os.uk/os-downloads). 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](https://docs.os.uk/os-downloads/products/addresses-and-names-portfolio/addressbase-fundamentals/release-notes); simply navigate to the new platform and click *Addressing and location portfolio* > *AddressBase Fundamentals* > *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.

It is important that COUs are processed with Deletes first, then Inserts and Updates. This is to ensure that updates are applied in the correct order. Guidance on this can be found in the '[Working with COU data' page in the AddressBase Core Getting Started Guide](/os-downloads/products/addresses-and-names-portfolio/addressbase-core/addressbase-core-getting-started-guide/working-with-cou-data.md).
