## Product updates

We are carrying out essential improvements to our product creation system. As a result, very small changes may be seen in Road Width values within OS MasterMap Highways Network. We estimate around 1.4 million features to be modified. Therefore, please be aware that the December release of OS MasterMap Highways Network will have a larger COU than usual.

## Next release

The next release of OS MasterMap Highways Network is scheduled for January 2025.
